WalkthroughMCP authentication now supports Basic and Bearer credentials across backend normalization, storage, MCP requests, discovery, and frontend setup flows. Manual authentication detects schemes, prepares credentials, and stores normalized authorization data before tool discovery. ChangesMCP authentication
Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🟡 Moderate · up to The PR adds Basic/Bearer authentication and credential persistence, but current behavior can still mishandle unsupported or blank credentials, attach credentials to the wrong MCP server, or use stale setup data. This could cause failed or unauthenticated MCP requests or misapplied credentials, so merge should wait for fixes or explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

Learning: In the frontend, the legacy Select component at `@/components/__legacy__/ui/select` is an intentional, codebase-wide visual-consistency pattern. During code reviews, do not flag or block PRs merely for continuing to use this legacy Select. If a migration to the newer design-system Select is desired, bundle it into a single dedicated cleanup/migration PR that updates all Select usages together (e.g., avoid piecemeal replacements).

Learning: In Significant-Gravitas/AutoGPT’s `autogpt_platform/frontend` (Vite + `vitejs/plugin-react` with the automatic JSX transform), do not flag usages of React types/components (e.g., `React.ReactNode`) in `.ts`/`.tsx` files as missing `React` imports. Since the React namespace is made available by the project’s TS/Vite setup, an explicit `import React from 'react'` or `import type { ReactNode } ...` is not required; only treat it as missing if typechecking (e.g., `pnpm types`) would actually fail.

Learning: In AutoGPT's frontend (autogpt_platform/frontend), prefer importing the non-legacy ScrollArea component from `@/components/ui/scroll-area` over `@/components/__legacy__/ui/scroll-area` for new or migrated code. The non-legacy component is a drop-in superset: it preserves the legacy component’s props and additionally supports the optional `showScrollToTop` prop—so reviewers should flag new legacy imports unless there’s a specific, documented reason they can’t use the non-legacy version.

Learning: Do not flag `import { Question } from "phosphor-icons/react"` as an invalid import. `Question` is a valid named export from `phosphor-icons/react` (as reflected in the package’s generated `.d.ts` files and re-exports via `dist/index.d.ts`), so it should be treated as a supported named export during code reviews.

Learning: Prefer using generated OpenAPI types from '`@/app/api/__generated__/`' for payloads defined in openapi.json (e.g., MCPToolsDiscoveredResponse, MCPToolOutputResponse). Use inline TypeScript interfaces only for payloads that are SSE-stream-only and not exposed via OpenAPI. Apply this pattern to frontend tool components (e.g., RunMCPTool) and related areas where similar SSE/openapi-discrepancies occur; avoid re-implementing types when a generated type is available.

Learning: When gating React component logic on a React Query result (e.g., hooks like `useQuery` / `useGetV2GetCopilotUsage`), prefer destructuring and checking `isSuccess` (or aliasing it to a meaningful boolean like `isSuccess: hasUsage`) instead of relying on `!isLoading`. Reason: `isLoading` can be `false` in error/idle states where `data` may still be `undefined`, while `isSuccess` indicates the query completed successfully and `data` is populated.

Learning: In the Copilot platform UI code, follow the established Orval hook `onError` error-handling convention: first explicitly detect/handle `ApiError`, then read `error.response?.detail` (if present) as the primary message; if not available, fall back to `error.message`; and finally fall back to a generic string message. This convention should be used for generated Orval hooks even if the custom Orval mutator already maps details into `ApiError.message`, to keep consistency across hooks/components (e.g., `useCronSchedulerDialog.ts`, `useRunGraph.ts`, and rate-limit/reset flows).

Do not add per-block try/except in individual block run() methods, as this is not the established pattern (e.g., Gmail, Slack, Todoist blocks omit it). Only use explicit try/except within blocks that need to distinguish between success and error yield paths inside a generator (e.g., attachment blocks). This guidance applies to all Python files under autogpt_platform/backend/backend/blocks/ and similar block implementations; avoid duplicating error handling in run() unless a block requires generator-based branching.

Learning: Cost billing via the cost(*costs) decorator is applied at input-evaluation time (before a block’s run() executes). Therefore, mutating input_data inside run() will not change billing. When a block’s billing depends on a field plus URL/sniff-derived signals, treat the explicitly declared billing field (e.g., is_video) as the only billing source—set it correctly before run() (or in the code path that occurs before the decorator evaluates input_data). This should be checked for all blocks under autogpt_platform/backend/backend/blocks/ so billing signals are not mistakenly assumed to update during run().

The block executor framework (backend/executor/manager.py) catches uncaught exceptions from run() and emits them on the 'error' output. Only add explicit try/except blocks when you need to control partial outputs in failure cases (e.g., certain outputs must not be yielded on error, as in attachment blocks). This is the standard pattern across the codebase; apply it broadly to blocks' run() implementations.

Reserve explicit try/except for scenarios where you must control partial output (e.g., attachment blocks that must skip yielding content_base64 on failure).

Learning: When using Python’s `unittest.mock.patch` in tests, choose the patch target based on how the imported name is resolved:
- If the code under test uses an **eager/module-level import** (e.g., `from foo.bar import baz` at module top), patch **the module where the name is looked up** (i.e., where it is used in the SUT), e.g. `patch("mymodule.baz")`.
- If the code under test uses a **lazy import** executed later (e.g., `from foo.bar import baz` inside a function/branch), patch **the source module** (e.g., `patch("foo.bar.baz")`) because the late `from ... import` will read the (potentially patched) name from the source module at call time.
For a concrete example: if `simulate_block` is imported inside an `if dry_run:` block in the SUT, then the correct test patch target is the source module path for `simulate_block` as it exists at call time (e.g., `patch("backend.executor.simulator.simulate_block")`), not the test file’s import location.

Learning: In the Significant-Gravitas/AutoGPT backend, treat `user_id` (an opaque UUID used only for correlation/tracing) as non-PII. Do not flag direct logging of `user_id` in `logger.warning`/`logger.info` statements as a PII exposure issue, as the established convention is to log `user_id` for tracing while reserving PII for fields like email or display name.

Learning: In the Significant-Gravitas/AutoGPT Python backend, when calling the OpenAI Python client `chat.completions.create`, construct the `messages` payload using the concrete typed-dict variants from `openai.types.chat` (e.g., `ChatCompletionSystemMessageParam`, `ChatCompletionUserMessageParam`, etc.) rather than trying to instantiate `ChatCompletionMessageParam` directly. `ChatCompletionMessageParam` is a `Union` alias and is not constructible, so `ChatCompletionMessageParam(role=..., content=...)` should fail type checking. Build each message element with the appropriate concrete typed dict and then annotate the resulting list as `list[ChatCompletionMessageParam]` (e.g., `messages: list[ChatCompletionMessageParam] = [ChatCompletionSystemMessageParam(...), ...]`).

Learning: In the AutoGPT backend Python code, do not flag naive datetime.datetime(...) constructors solely for omitting tzinfo: autogpt_platform/backend/pyproject.toml does not enable Ruff rule DTZ001, so these constructors do not fail the backend Ruff check for that reason alone.

Learning: In the AutoGPT backend, do not report missing mutable class-attribute annotations as required lint fixes for Ruff rule RUF012, because Ruff is pinned to version 0.15.0 and the repository configuration does not select RUF012. Reconsider this guidance if the pinned Ruff version or configured rule selection changes.

📋 Automated Review — PR #14075
PR #14075 — feat(platform): support Basic authentication for MCP servers
Author: Torantulino | Files: 36
🎯 Verdict: REQUEST_CHANGES
PR Description Quality
✅ Has Why + What + How — unusually thorough, with a manual-test matrix. Two claims in it do not match the code, though: the "both ends require a token68 single-run remainder" claim (backend still uses split(None, 1)) and the credentials_optional claim (see Should Fix #10). The - [ ] Full CI green box is still unticked while CI is in fact green.
What This PR Does
MCP servers previously only worked with Bearer tokens; servers like Langfuse that want HTTP Basic auth could not be connected at all. This PR adds a Bearer/Basic scheme selector to all four MCP connection surfaces, canonicalizes the pasted credential into a single "<Scheme> <credential>" string exactly once at the API boundary, records the chosen scheme in credential metadata so the transport never has to re-parse the secret, and probes the server with the credential before reporting "Connected". It also stops manual credentials from churning their ID on rotation (so saved graph nodes keep resolving) and closes MCP sessions after discovery and block execution.
The prior round's blocker — normalize_mcp_authorization running at both the persistence and transport boundaries, producing Bearer Bearer <cred> on the wire — is ✅ Addressed at df60664: MCPClient now takes the authorization value verbatim and mcp_authorization_header reads the scheme from metadata.
Specialist Findings
🛡️ Security client.py:42 before the value reaches _build_headers), SSRF is layered (validate_url_host + IP-pinning + _remove_insecure_headers stripping Authorization on cross-origin redirects), auth_token is now SecretStr, and managed credentials are correctly skipped in the supersede scan. No cross-user access or auth bypass found. The prior round's server-side-Basic-validation gap is ✅ Addressed.
🟠 Storing a manual credential deletes the user's OAuth row via creds_manager.delete (routes.py:539), which — contrary to the comment on routes.py:535 — only drops the DB row and never calls handler.revoke_tokens. The refresh token stays live at the provider with no way to revoke it. (routes.py:507, :539)
🏗️ Architecture mcp-auth.ts:4 vs client.py:58), and the validate → probe → store → upsert sequencing is written out longhand in three components with the provider-upsert fix landing in only one. Also a new feature-router → feature-router import (mcp/routes.py:15 pulling to_meta_response from integrations/router.py) with MCP metadata knowledge leaking into the integrations router.
🟠 The MCPClient close-invariant landed on three of four sites; run_mcp_tool.py:298 — the highest-traffic path — still leaks.
⚡ Performance MCPClient opens a fresh aiohttp.ClientSession + TLS handshake per request (util/request.py:509), so the added session DELETE takes tool execution from 3 → 4 connections (+33% setup) and is awaited before the result is returned. The connect probes fetch a full tool catalogue (~67KB on a Notion-class server, per this repo's own comment) purely to check a 401, then discard it.
🟠 close() builds Requests(raise_for_status=False) with no retry_max_attempts (client.py:370); I verified Requests.request only installs a stop condition when that argument is set (util/request.py:429), so a 429/5xx to the DELETE retries forever with up to 300s backoff. Downgraded from the specialist's "critical": the same unbounded behavior already applies to _send_notification (client.py:250) and discover_auth (client.py:280) on the same request paths pre-PR, so this is a latent module-wide property the PR extends rather than introduces. Still worth bounding here.
🧪 Testing
🟠 test_normalize_mcp_authorization_preserves_bare_credential_with_spaces (test_auth_schemes.py:64) asserts on "orgid api-key", whose first word is not a scheme keyword — it passes identically with or without the rule it is named for. And both new finally: await client.close() blocks are stubbed ten times and asserted zero times; deleting them leaves the backend suite green.
📖 Quality getAPIResponseError is byte-identical across two files and getErrorMessage has opposite precedence in each (MCPToolDialog.tsx:80 prefers message, McpConnectPanel.tsx:300 prefers detail), so one backend 422 renders differently on two surfaces. normalizeMcpUrl exists three times. MCPToolDialog.tsx is 783 lines with no extraction; mcp_store_token is a 104-line function. Comments frequently narrate the review rather than the code (useMCPAuthScheme.ts:11 references an identifier named touched that does not exist at head).
📦 Product
📬 Discussion ✅/CHANGES_REQUESTED with the re-review at head still in flight. Note the review-integrity caveat: authorship transferred @Torantulino → @kcze mid-review, and @kcze resolved all 17 threads — including ones he filed himself — with no independent verifier.
🟠 The #13683 storage-shape collision (APIKeyCredentials.api_key vs OAuth2Credentials.access_token) has been escalated twice with no maintainer answer; whichever PR merges second breaks manual MCP credentials.
🔎 QA Basic header, plus forged a legacy pre-PR credential row (no mcp_auth_scheme) and confirmed it still goes out as Bearer — that is strong evidence for the headline behavior and for backward compatibility. Browser testing of the three UI surfaces did not run: the session aborted with an inference-route error before any screenshots were captured. The Blocker below is therefore code-traced, not visually confirmed.
🔴 Blockers
- The URL field's "don't discard work in progress" guard is a no-op, wiping the typed credential on every keystroke (
frontend/src/app/(platform)/build/components/MCPToolDialog.tsx:477) — I read the handler at head to confirm.const serverChanged = serverUrl.trim() !== nextUrl.trim()is true for any non-whitespace edit, so the block it guards always runs:setManualToken(""),resetScheme(),setShowManualToken(false). The comment directly above claims the opposite ("Clearing on every keystroke meant fixing one character of the path threw away the typed credential"). Concrete path: builder → add MCP block → enter URL → discover → 401 → "enter an API credential manually" → paste the Basic credential → notice the URL needs a/mcpsuffix → the first character typed clears the credential and collapses the panel, forcing another discover → 401 → OAuth-probe round trip. Product traceddev's handler as a baresetServerUrl(e.target.value), making this PR-introduced. One-line fix: compare normalized server identity (origin + path, asnormalizeMcpUrlalready does) rather than raw trimmed strings, or defer the reset toonBlur/connect. (Flagged by: product — 1, verified independently by lead)
🟠 Should Fix
- The two normalizers disagree, and the test named for the case can't see it (
frontend/src/lib/mcp-auth.ts:4,backend/blocks/mcp/client.py:58,backend/blocks/mcp/test_auth_schemes.py:64) — TS requires a single\S+remainder; Python usessplit(None, 1). PastingBearer orgid api-keyyieldsBearer Bearer orgid api-keyon the wire; a direct API caller sendingbearer org keygets the first word of their secret eaten. Probe-before-store means this now fails loudly rather than silently, which is why it isn't a blocker — but the PR description claims both ends already agree. Add a shared accepted/rejected fixture table asserted by both suites. (Flagged by: architect, testing, quality — 3) - Bound
MCPClient.close()(backend/blocks/mcp/client.py:370) — passretry_max_attempts=1and wrap inasyncio.wait_for(..., timeout=5)so best-effort cleanup can never outlive the operation it cleans up after. Verified: nostopcondition is installed without that argument (util/request.py:429). (Flagged by: performance — 1) - Close the copilot client (
backend/copilot/tools/run_mcp_tool.py:298) — the probe at:292got afinally, the discovery/execution client did not, and it runs on every copilot tool call. MakingMCPClientan async context manager would cover all four sites at once. (Flagged by: architect, performance — 2) - OAuth refresh tokens are orphaned, and the deletion is unconfirmed (
backend/api/features/mcp/routes.py:507,:539) — either route through the revocation pathDELETE /credentialsuses (integrations/router.py:1044), or leave the OAuth row alone; and correct the comment at:535, which asserts revocation that does not happen. A confirmation step matters here because destroying that row also breaks every saved graph node bound to its ID. (Flagged by: security, product — 2) - Credential ranking can pin execution to a stale OAuth row (
backend/blocks/mcp/helpers.py:176) — ranking byaccess_token_expires_at or 0means a manual credential (alwaysNone) always loses to a surviving OAuth row. Since the supersede loop swallows delete failures tologger.debug(routes.py:540), one failed delete permanently pins the user to the old token while all three UIs report "Connected" from an explicit-credential probe. (Flagged by: security — 1) - Assert the session-close fixes (

Cover both the success and raising paths. (Flagged by: testing — 1) mcpStoreTokenhas no test of the real implementation (frontend/src/providers/agent-credentials/credentials-provider.tsx:206) — this is the fix for the "MCP: … was removed" bug, and deleting theupsertCredentials("mcp", credsMeta)call at:223leaves the suite green. Author-admitted open ("(a) is still not covered"). (Flagged by: testing, discussion — 2)McpConnectorRowskipsvalidateMCPAuthCredential(frontend/src/app/(platform)/copilot/components/ChainActionCard/McpConnectorRow.tsx:44) — the other three surfaces call it. This surface relies onMCPSetupCardre-deriving the scheme from the prepared string, which is the re-parse-the-secret pattern this PR exists to eliminate. Severity dropped from last round (the server-side guard now catches the unencodeduser:passwordcase), but the user gets a raw 422 instead of the message naming the Base64 step. (Flagged by: product, testing, architect — 3)- Dangling
aria-describedby(frontend/.../McpConnectorRow.tsx:106) —hintIdis referenced by the input but no element carries it; the hint<p>at:100needsid={hintId}. That hint is the only place the Base64 step is explained. (Flagged by: quality, product — 2) - Reconcile the
credentials_optionalclaim with the behavior (frontend/.../NewBlockMenu/Block.tsx:91) — the two specialists who looked at this disagree: architect readsexecutor/utils.py:494as meaning already-saved MCP nodes keep getting skipped; product reads the block'sdefault={}as making the field unconditionally optional, so removing the flag changes only the toggle's rendered state. Note that either way this is not a regression — existing nodes behave exactly as they did before. Please state which is true and fix the PR description or the schema accordingly. (Flagged by: architect, product — 2) - Dark-mode contrast regressions (
frontend/.../MCPToolDialog.tsx:502,:548) — the manual-credential button lost itsdark:text-gray-400variants and the error text wenttext-red-500→text-red-700with no dark variant, in a file that usesdark:extensively at:673-772.:548is where the new Basic validation messages render.

backend/blocks/mcp/client.py:42) — the scan runs on the raw value,.strip()happens at:45, so a token copied with a trailing newline is now rejected as "must be a single line" where it previously worked. (Flagged by: security — 1) - Get a maintainer decision on the #13683 storage collision (
backend/api/features/mcp/routes.py:524) — ~130 conflicting lines in this file alone; whichever merges second breaks manual MCP credentials. Also unmentioned: the author's own sibling PRs #14300/#14302/#14303 overlap this one. (Flagged by: discussion — 1)
🟡 Nice to Have
- Extract

probe_onlyflag toDiscoverToolsRequest— credential validation currently downloads and discards the whole tool catalogue. (performance) - Consolidate
lib/api-error.tsand movenormalizeMcpUrlintolib/mcp-auth.ts; splitMCPToolDialog.tsx(783 lines) andmcp_store_token(104 lines). (quality, architect) - Rebuild
MCPAuthSchemeFieldonatoms/Select— it currently ships four visually distinct controls via fourselectClassNamestrings, against its own "one implementation rather than four" docstring. (product, quality) - Move
normalize_mcp_authorizationnext tomcp_authorization_header(ablocks/mcp/auth.py), have it return(scheme, credential)soroutes.py:502stops re-splitting the string it just built, and relocate_is_mcp_credentialout of the integrations router. (quality, architect) asyncio.gatherthe supersede deletes (routes.py:537) — each takes a Redis lock plus a whole-blob rewrite, serially, on the response path. (performance)
🔵 Nits
- Comments narrate the review, not the code —
useMCPAuthScheme.ts:11(references atouchedidentifier that doesn't exist at head),helpers.py:66,routes.py:140,run_mcp_tool.py:219, and several test docstrings ("Deleting the clearing left every assertion green"). - Scheme-aware placeholder (
McpConnectorRow.tsx:108,MCPSetupCard.tsx:469,McpConnectPanel.tsx:240) — "Paste API token" under a Basic hint. manual_credentials[-1]is called "the newest" (routes.py:508) butget_creds_by_providerguarantees no ordering — sort or reword.("basic", "bearer")re-listed (integrations/router.py:279) next to theLiteralat:236.- No
max_lengthon credential fields (routes.py:55,:424) — the control-char scan runs over an unbounded string. - Dead
if client is Nonebranch (run_mcp_tool.py:253) with six lines of comment defending an unreachable state, now contradicted by the comment added at:219.
Human Review Needed
YES — Required because at least one specialist reported a high or critical finding.
Risk Assessment
Merge risk: MEDIUM | Rollback: MODERATE — a plain revert leaves credential rows already written with mcp_auth_scheme metadata and a "Basic <cred>" value in access_token, which the reverted code would re-send as Bearer Basic <cred>. Any rollback needs a cleanup pass over manual MCP credential rows.
CI Status
GitHub CI (reported by the discussion specialist at head 7819fe5): 48/48 completed checks green — backend test 3.11/3.12/3.13, type-check, lint, integration_test, e2e, CodeQL, Snyk, codecov gates. Merge state BLOCKED on REVIEW_REQUIRED + unsigned CLA, not on checks.
Local harness: 4/5 passed — frontend lint, types, test:unit, build all green. cd autogpt_platform/backend && poetry run lint failed locally after 107s. GitHub CI ran the same lint job green on this head, so per policy I'm treating the local failure as sandbox environment skew and not as a finding; worth a glance if it reproduces on the author's machine.
UI Testing — Variant Results
✅ local: I'll start with the mandatory environment check. Token is empty — need to create the test user. Signup worked with a longer password. Getting a backend token now.
❌ hosted: I'll start with the mandatory environment setup and auth. Token came back empty. Running the sign-up fallback. Backend has the PR code. Now exercising /api/mcp/token normalization end-to-end.
Addresses the fourth automated review on #14075. Blocker: the builder dialog's "only a real change of server identity discards work in progress" guard compared trimmed URLs, so it fired on every keystroke and cleared the typed credential — the exact flow the dialog exists to enable. Compare server identity (origin) instead, via a shared `lib/mcp-url.ts` that also replaces the two copies of `normalizeMcpUrl`. Also: - Reconcile the two implementations of the credential grammar. The TS side required a single token68 run after the scheme word while the backend used `split(None, 1)`, so `Bearer orgid api-key` was scheme-prefixed to one and bare to the other, and the frontend rewrote it to `Bearer Bearer orgid api-key`. `mcp_auth_cases.json` is now read by both suites. - Strip before scanning for control characters, so a token copied with a trailing newline is no longer rejected as "must be a single line". - Bound `MCPClient.close()` with `retry_max_attempts=1` and a 5s timeout; without a `stop` condition a 429/5xx retried forever. - Close the copilot client on the discovery/execution path, the highest-traffic MCP path in the product. - Stop deleting the user's OAuth row when a manual credential is stored: neither `creds_manager.delete` nor `delete_acquired` revokes, so it orphaned a live refresh token and broke saved graph nodes bound to that ID. Rank manual credentials above OAuth ones in `auto_lookup_mcp_credential` instead, and correct the comment that claimed revocation. - Validate in `McpConnectorRow` before submitting, give its hint the id the input points at, and make the placeholder track the selected scheme. - Stabilise the `useMCPAuthScheme` callbacks so memoized callers cannot pin the first render's stored scheme, defeating Basic seeding. - Restore the dark-mode variants lost on two `MCPToolDialog` elements. - Bound the credential fields at 8192 chars and share the scheme `Literal`. Tests: regression coverage for the URL-edit blocker, the shared grammar table, the trailing newline, both session-close paths, the credential ranking, the connector-row validation and aria wiring, and — closing the round-three gap — the real `mcpStoreToken` implementation rendered through `CredentialsProvider`. Each was checked to fail without its fix. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

📋 Automated Review — PR #14075
PR #14075 — feat(platform): support Basic authentication for MCP servers
Author: Torantulino | Files: 39
🔴 Verdict: Changes needed — 6 items to fix before approval; not approved.
PR Description Quality
✅ Has Why + What + How — the motivating Langfuse Basic-auth case, the accepted credential grammar (bare / Bearer … / Basic … / full header), the single-normalization design, and the deliberate choice to keep the three connection GUIs separate are all documented.
What This PR Does
Previously, manual MCP server credentials could only be sent as Bearer tokens. This PR lets a user paste a Basic (or full Authorization:) credential and adds a Bearer/Basic selector with scheme-specific guidance to all four MCP connection surfaces (builder dialog, setup card, integrations panel, copilot connector row). Credentials are normalized exactly once at the input boundary (normalize_mcp_authorization), stored verbatim, and read back via mcp_authorization_header without re-parsing — closing the double-prefix and header-injection classes of bug. A discover-before-store probe replaces the removed validation gate so a revoked/invalid credential no longer shows a false "Connected", and sessions are now closed in finally blocks to stop leaking remote session rows.
Specialist Findings
🛡️ Security ✅ — Attacked the normalization, rotation, and SSRF surfaces and found no reachable vulnerability. CRLF/C0/DEL injection is rejected, SSRF host validation is preserved on both endpoints, credentials never appear in responses or logs, and the OAuth row is deliberately not clobbered on rotation. Only a 🔵 defense-in-depth gap (C1 controls / U+2028/U+2029 not rejected — not exploitable; httpx re-validates at send).
🏗️ Architecture ✅ — Clean single-normalization boundary, shared cross-language contract fixture (mcp_auth_cases.json), consistent session lifecycle. 🟠 is_manual_mcp_credential is field-inspection type dispatch on a shared OAuth2Credentials type (helpers.py:40) — acknowledged debt tracked to #13683. Minor placement/DRY/comment-durability nits otherwise.
⚡ Performance ✅/await client.close() is awaited inline on the response path (run_mcp_tool.py:353, block.py:181), adding up to 5s (_CLOSE_TIMEOUT_SECONDS) of tail latency to an already-computed result on the highest-traffic MCP path.

📖 Quality getErrorStatus/getErrorMessage/getAPIResponseError) is copy-pasted between MCPToolDialog.tsx:74 and McpConnectPanel.tsx:313, MCPAuthSchemeField uses a raw native <select> bypassing the design system, and mcp_store_token is ~110 lines.
📦 Product ✅/
📬 Discussion ✅ — Head 072d77a is MERGEABLE, all required GitHub checks pass, and every human review thread (@kcze) is verified resolved by later commits; @ntindle's review is dismissed.
🔎 QA :/whitespace Basic rejection, empty-token 422, and credential rotation (same id, scheme flipped bearer→basic, exactly one row per server — no duplicate growth). Frontend browser QA of the selector could not be completed — the harness hit an inference-route error rendering page images, so the builder selector was not visually verified this round.
✅ Resolved Since Last Review
- OAuth row no longer clobbered on rotation — security confirms the rotation logic refuses to rewrite/delete an OAuth row in place (was prior architect High).
- Stale-expiry and refresh-gate test gaps closed —
test_store_token_clears_stale_expiry_on_rotationandtest_expiring_credential_is_refreshednow exist as positive guards (were prior testing Highs). - Credential persisted through the provider so the builder node binds to the returned ID (was prior ui-reviewer "was removed" High).
- Basic
:/whitespace rejected pre-flight with actionable copy (mitigates the prior product Base64 / discussion validation-gate concern).
🟠 Should Fix
- Untested
close()bounding logic (autogpt_platform/backend/backend/blocks/mcp/client.py:365) — the entire justification for the change (timeout +retry_max_attempts=1) has zero coverage; all tests mockclose. Drive the real impl with a hanging/429 DELETE and assert it is bounded and swallowed. (Flagged by: testing) - Inline session close adds up to 5s tail latency on the hottest path (
autogpt_platform/backend/backend/copilot/tools/run_mcp_tool.py:353, alsoblocks/mcp/block.py:181) — dispatch the already best-effortclose()fire-and-forget, or drop the timeout to 1–2s. (Flagged by: performance) - Error-extraction helpers copy-pasted across surfaces (
autogpt_platform/frontend/src/app/(platform)/build/components/MCPToolDialog.tsx:74and.../McpConnectPanel.tsx:313) —getErrorStatus/getAPIResponseErrorare byte-identical; extract one shared helper. (Flagged by: quality) MCPAuthSchemeFielduses a raw native<select>(autogpt_platform/frontend/src/components/contextual/MCPAuthSchemeField/MCPAuthSchemeField.tsx:48) — bypasses the design system and pushes styling onto every caller via className props, reintroducing the drift the shared field was meant to end. Use the design-system Select. (Flagged by: quality)- Builder dialog drops the scheme-specific placeholder (
autogpt_platform/frontend/src/app/(platform)/build/components/MCPToolDialog.tsx:532) — hardcodes a generic string while the other three surfaces usemcpAuthTokenPlaceholder(scheme); the primary place agents are wired loses the Base64 cue. (Flagged by: product, quality — 2 specialists) - Builder re-implements
normalizeMcpUrlinline (autogpt_platform/frontend/src/app/(platform)/build/components/MCPToolDialog.tsx:140) —.trim().replace(/\/+$/,"")risks divergence from the backend URL-matching mirror the siblings use. (Flagged by: architect, quality, product — 3 specialists)
🟡 Nice to Have

🔵 Nits

(architect)mcpStoreTokenthrows raw unlike sibling callbacks that wrap inonFailToast(autogpt_platform/frontend/src/providers/agent-credentials/credentials-provider.tsx:206) — add a comment noting the deliberate deviation. (architect)DiscoverToolsRequest.auth_tokenmin_length=1turns a previously-tolerated empty string into a 422 for non-frontend callers (autogpt_platform/backend/backend/api/features/mcp/routes.py:50). (architect)- Change-relative comments at
run_mcp_tool.py:238,:230, andMCPToolDialog.tsx:135narrate the diff rather than the standing behavior — rewrite to durable facts or delete. (architect)
Human Review Needed
YES — Required by the review lead's security-boundary assessment.
Risk Assessment
Merge risk: MEDIUM | Rollback: EASY (feature is additive and gated behind the manual-credential flow; revert restores Bearer-only behavior)
CI Status
GitHub CI: ✅ green — 49 checks passed on head 072d77a (authoritative).
Local harness: frontend lint/typecheck/unit tests/build all ✅; backend poetry run lint ❌ — this suite is green on GitHub CI for the same head, so the local failure is environment skew, not a finding (per rule 13).
UI Testing — Variant Results
❌ local: I'll start with the mandatory Bash call to authenticate and verify services. Token looks empty. Let me debug the auth. The test user doesn't exist. Let me sign up.
✅ hosted: MCP Basic auth support verified end-to-end: store/normalize/rotate correct, scheme surfaced in credentials list, all validation rejections (422/401) fire, Bearer/Basic UI selector + scheme guidance + client-side validation work, backward-compat bare→Bearer and credential-less public discovery intact.
- low: HOSTED variant: a manually-entered Basic MCP credential is labelled "(OAuth)" in the credential picker because manual creds are stored as OAuth2Credentials. Observed indirectly via /api/integrations/credentials returning type=oauth2 for all MCP creds. Pre-existing and disclosed in the PR as deferred to #13683 — noted, not blocking.
Drop the session-close work (a pre-existing leak, out of scope for Basic auth), the credentials_optional change and its test, and the narrative comments accumulated across review rounds. Share the error-extraction helpers between the builder dialog and the integrations panel, fold the inline backend normalization cases into the shared fixture, and give the builder dialog the same scheme-specific placeholder and URL helpers as the other surfaces.

Round 5 (
|
| # | Item | Outcome |
|---|---|---|
| 1 | Untested close() bounding logic |
Moot — session-close work removed from the PR. On dev, MCPClient.close() is only called on the copilot probe path. The missing close on the block, discovery and copilot tool paths is a pre-existing leak unrelated to auth schemes; it was added in round 2 to satisfy a finding and has generated follow-on findings every round since. It belongs in its own PR, ideally as an async context manager on MCPClient, and this commit's revert is the patch for that. |
| 2 | Inline close adds tail latency on the hot path | Moot — same removal. |
| 3 | Error-extraction helpers copy-pasted | Done. frontend/src/lib/mcp-errors.ts; both surfaces import it, the local copies are gone. |
| 4 | MCPAuthSchemeField uses a native <select> |
Declined, with reason. atoms/Select is a Radix portal select built on __legacy__/ui/select. Switching changes the interaction model in every test that drives the selector across four suites, and adds lines to a PR being cut back. Two of the four surfaces already render a raw <input> beside the field, so a native <select> styled to match is the consistent choice within each surface. Happy to make the swap as a follow-up if a maintainer wants it. |
| 5 | Builder dialog missing the scheme-specific placeholder | Done. mcpAuthTokenPlaceholder(manualAuthScheme). |
| 6 | Builder re-implements normalizeMcpUrl inline |
Done. |
Also taken: 🟡 4 (the integrations panel now compares server identity by origin, matching the builder dialog) and 🔵 5 (change-relative comments removed everywhere, not just at the three lines named — AGENTS.md says to avoid comments unless the code is complex, and most of the ones here narrated review history).
Also removed as out of scope: the credentials_optional change in Block.tsx and the 103-line test that only guarded it. Last round established that it has no execution effect either way, so restoring the dev line is the smaller change.
Not taken: 🟡 1/2/3/5/6 and 🔵 1–4. Each would add code to a PR whose problem is size, and none affects correctness. 🟡 1 (is_manual_mcp_credential as a typed discriminator) is the #13683 decision, which is still open for a maintainer.
Verified locally: backend poetry run lint --skip-pyright and pyright clean; 87 + 42 + 42 MCP tests pass. Frontend pnpm types, pnpm lint clean; full vitest run 571 files / 6127 tests pass.

…ted-card Conflicts, both resolved to keep #14075's Basic-auth support and this branch's rejected-credential state: - copilot/tools/run_mcp_tool.py: the surface_connect_card probe reuses dev's client, built with mcp_authorization_header(creds), and still records the CredentialRejection. - MCPSetupCard/__tests__/MCPSetupCard.test.tsx: both sides' new tests. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…-the-2026-07-28-spec-stateless-core Resolves conflicts with #14075 (Basic auth for MCP servers): keep the `authorization` parameter name from dev while retaining `input_schema` forwarding and client cleanup from this branch. Adapt the new discover-tools test to the awaited `client.close()` and the MCPSetupCard chain-callback test to the forwarded `iss` argument. Co-authored-by: Claude Fable 5.1 (Claude Code) <noreply@anthropic.com>
dev landed #14075 (Basic auth for MCP servers), which independently fixed the same root cause from the MCP side: `is_manual_mcp_credential` now gates the `refresh_if_needed` call so a pasted credential never enters the OAuth refresh path. Conflicts resolved in favour of dev's approach, keeping this branch's additions layered on top: - helpers.py: dev's refresh gate; kept the note on why a failed refresh must yield None rather than a stale token. - routes.py: dev's in-place credential rotation and Basic/Bearer normalization, with the HTTPS requirement and the bounded verification probe in front of it. The probe now sends the complete Authorization header dev stores, not a bare token. - MCPSetupCard.tsx: dev's scheme selection and rewritten manual-token UI, with this branch's `isFetchedAfterMount`/`isError` guard and the "Verifying…" label. Dev's client-side pre-verification supersedes the UI half of the rejection-detail test; the backend 400 stays covered in test_routes.py. - test_helpers.py: both test sets kept. `_may_need_refresh` in creds_manager is retained. It is no longer load-bearing for MCP now that dev gates the call, but it is provider-agnostic and still removes a Redis round-trip for every non-expiring OAuth2 credential. Test harness: dev made `_invoke_creds_changed_hook` async and it now publishes over Redis, which hung the e2e harness; stubbed alongside the existing lock stub. MCPClient's `auth_token` is now `authorization` and carries a complete header, so assertions were updated. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Three groups of tests were characterising behaviour this branch does not change, or duplicating a case that already exists: - ``mcp_manual_token_e2e_test.py``: the token reaching the client, the connect card, 401 invalidation, per-user isolation. All four pass on unmodified ``dev`` — #14075 fixed the resolve-to-``None`` bug they were written for. ``test_scope_level_403_keeps_the_credential`` did discriminate, but ``test_run_mcp_tool.py``'s 401/403 parametrisation covers the same behaviour. - ``test_helpers.py``: ``resolves_static_token_credential``, ``unmatched_server`` and ``store_fails`` characterise ``auto_lookup_mcp_credential`` branches this PR leaves alone. - ``MCPSetupCard.test.tsx``: "keeps Connected across a background refetch" had setup identical to the test above it — ``makeSetupOutput(undefined, false)`` is ``makeSetupOutput()`` and ``fetchedAfterMount`` already defaults to ``true`` — and asserted a strict subset of its assertions. The mock never exposes ``isFetching``, so it could not have caught the regression its comment named. Kept the two round trips in the e2e module. They are not the ones flagged: both exercise ``normalize_mcp_url``, which this PR now changes, and a storage-vs-lookup disagreement is invisible from either side alone — that is the regression 310a389 fixes, and only a round trip catches it. 173 lines out, 13 in. 111 tests still pass across the touched suites.

dev(1 conflict:McpConnectPanel.tsx—devchangedonSuccessto hand back aCredentialsMetaResponsewhile this branch added the scheme selector and explicit status checks; resolved by keeping both).Three fixes on top of the merge:
/mcp/tokenbut resolves that ID againstCredentialsProvidersContext, which the direct endpoint call never updated — so a first-run manual connect rendered "MCP: … was removed. Choose a connection to keep this agent running." on the node it had just configured, until a page reload. AddsmcpStoreTokento the provider, next tomcpOAuthCallback, which already upserts the same way. The direct-endpoint path stays as a fallback for callers rendered outside the provider.normalize_mcp_authorizationnow runs exactly once, where a human-supplied value enters the system; stored credentials go throughmcp_authorization_header, which reads the scheme from metadata and never inspects the secret. A scheme word takes the whole remainder after it —value.split(None, 1)on the backend, the same split inmcp-auth.ts— soBearer orgid api-keymeans what the user meant by it.backend/blocks/mcp/mcp_auth_cases.jsonis the shared accepted/rejected table, asserted by both suites. The UI rejects a Basic credential containing:or whitespace up front, and the backend rejects it again for direct API callers./mcp/tokenonly says the row was written, so both surfaces reported "Connected" for a credential the server rejects — reproduced against Langfuse with card=Connected, DB=status=revoked. Both now discover first, matching what the builder dialog already did.Verified:
pnpm vitest run→ 6108 passed (571 files);pnpm types,pnpm lint,pnpm formatclean;ruff check/ruff formatclean on the changed backend files. Backend pytest was not run locally (the docker test stack collides with a pre-existing dev-stack container in this environment) — relying on CI for it.Not addressed here, deliberately: the
DELETEon a manually stored MCP credential returning 400 (missing 'mcp_token_url' metadata) is a pre-existing bug on the generic revoke path that already affects manual Bearer credentials and needs its own fix; the credential picker labelling a manual Basic credential "(OAuth)" is an artifact of storing manual credentials asOAuth2Credentials, which #13683 changes; the duplicatedPOSTper submit is React StrictMode in the dev container and the endpoint is idempotent.Update: scope trimmed at
4551dc1The PR had grown to ~4,000 added lines over four bot review rounds, most of it not Basic auth. This commit removes 747 lines and adds 215:
dev,MCPClient.close()was only ever called on the copilot probe path; the missing close on the block, discovery and copilot tool paths predates this PR and has nothing to do with auth schemes. Reverting it also removes the two new Should Fix items about its timeout and its tests. It should come back as its own small PR, ideally as an async context manager onMCPClient.credentials_optionalis untouched again. Thedevline inBlock.tsxis restored and the test that only guarded its removal is gone. Last round established that it has no execution effect either way.AGENTS.md. The remaining comments state invariants, not history.lib/mcp-errors.tsinstead of duplicated between the builder dialog and the integrations panel.mcp_auth_cases.json, so one table drives both suites and the duplicated frontend cases are gone.Also in this commit: the builder dialog uses the same scheme-specific placeholder and
normalizeMcpUrlas the other surfaces, and the integrations panel compares server identity by origin so editing the path no longer discards a typed credential.
