+# 1inch MCP Server
+
+This skill teaches agents how to wire and use the **1inch MCP server** so users get docs, examples, and (with auth) swaps and APIs without re-explaining setup each session.
+
+## When to use this skill
+
+Load this skill whenever the user’s goal depends on the **1inch MCP server** (tools, URL, or auth) or on **1inch Business** product APIs from an AI-assisted workflow.
+
+**Documentation and discovery** (`search`)
+
+- Explain or find behavior in 1inch docs: APIs, slippage, supported chains, rate limits, error codes, SDK usage.
+- Compare approaches (e.g. classic vs Fusion vs cross-chain) or look up parameters before coding.
+
+**SDK examples** (`list_examples`, `get_example`)
+
+- Show runnable example code: swap flows, limit orders, chain-specific snippets.
+- Pull source from a named example package for copy-paste or review.
+
+**MCP resources** (server `resources` / `read`, if the client lists them)
+
+- Use bundled guides: **swap workflow**, **classic / Fusion / cross-chain** swap guides, **quote** guide, **orderbook workflow**, and the **API index**; plus **SDK examples** as a resource—when the user wants a single structured document instead of or alongside `search`.
+
+**Swaps and routing** (`swap` — requires auth)
+
+- The tool does the heavy work server-side: routing, quotes, and assembling **ready-to-use** data (e.g. unsigned transaction parameters, typed data, or follow-up steps for Fusion/cross-chain). The user or wallet only **signs** and **submits** what the tool returns—no hand-built calldata in the client for normal flows. Supports **classic**, **Fusion (intent)**, and **cross-chain**; `quoteOnly` for inspection without execution.
+
+**Limit orders** (`orderbook` — requires auth)
+
+- Same idea: `build` runs server-side order construction; the response is **EIP-712 (or similar) data ready to sign**—then `create` with the signature, or `list` / `cancel` for lifecycle. The tool carries the orderbook API complexity; the user supplies signing and on-chain follow-through.
+
+**Other product HTTP APIs** (`product_api` — requires auth)
+
+- Call 1inch product endpoints exposed via the gateway: e.g. **portfolio**, **spot price**, **gas price**, **token** metadata, and other [documented](https://business.1inch.com/portal/llms.txt) paths—without re-inventing base URLs and auth for each call.
+
+**Operations and support** (`debug` — requires auth, **optional** tool)
+
+- Look up **organization-scoped** application logs (e.g. by `x-request-id` or time window) when the server exposes this tool and the user is debugging production or API behavior for their org.
+
+**Client setup and configuration**
+
+- Wire **MCP in Cursor, VS Code, Claude Desktop, Claude Code, Codex, Gemini CLI**, or other HTTP/stdio clients; set **`https://api.1inch.com/mcp/protocol`**, headers, or supergateway.
+- Use **API keys**, **OAuth**, or understand **which tools are public vs authenticated**.
+
+**General triggers**
+
+- “Connect 1inch to my IDE / agent / MCP” or “how do I authenticate for 1inch MCP.”
+- Building or integrating a **dapp, bot, or backend** that uses 1inch Business APIs with AI help.
+
+If the question is only **unrelated off-chain** topics with no 1inch API or MCP angle, you do not need this skill.
+
+## Server URL (production)
+
+`https://api.1inch.com/mcp/protocol` (Streamable HTTP)
+
+## Client setup (summary)
+
+| Client                           | Transport | Config pattern                                                                                                             |
+| -------------------------------- | --------- | -------------------------------------------------------------------------------------------------------------------------- |
+| Cursor                           | HTTP      | `.cursor/mcp.json` -> `"url": "https://api.1inch.com/mcp/protocol"`                                                        |
+| VS Code Copilot                  | HTTP      | `.vscode/mcp.json` -> `type: "http"`, same URL                                                                             |
+| Claude Code / Codex / Gemini CLI | HTTP      | CLI `mcp add` with `--transport http` and the URL                                                                          |
+| Claude Desktop                   | stdio     | Launch `npx -y supergateway --streamableHttp <URL> --outputTransport stdio` (see [references/AUTH.md](references/AUTH.md)) |
+
+Prefer **HTTP** when the client supports it; use **supergateway** only for stdio-only clients.

+
+## Authentication
+
+- **API key:** `Authorization: Bearer <key>` on the HTTP transport where the client allows headers.
+- **OAuth:** Supported by the server for interactive login when no API key is set.
+
+Details and client-specific snippets: [references/AUTH.md](references/AUTH.md).
+
+## Example prompts (for the user)
+
+- "Search 1inch docs for how to set slippage on Base."
+- "Show the TypeScript swap example for Fusion on Ethereum."
+- "Quote swapping 100 USDC to ETH on Arbitrum" (requires auth for execution tools).
+- "List my open limit orders on Ethereum" / "Build a limit order to sell 1 WETH for USDC" (auth).
+- "What's my portfolio value on Arbitrum?" or "Fetch spot price for this token" via `product_api` (auth).
+- "Find logs for request id … in the last hour" when `debug` is available (auth).
+
+## Progressive disclosure
+
+- Load [references/TOOLS.md](references/TOOLS.md) when you need exact tool arguments or edge cases.
+- Load [references/AUTH.md](references/AUTH.md) when configuring headers, OAuth, or Claude Desktop bridging.
+
+## Legal
+
+Use of the MCP server is subject to 1inch Business Portal terms linked from the [product documentation](https://business.1inch.com/portal/documentation/ai-integration/mcp-server).

+# Authentication -- 1inch MCP
+
+## API key
+
+Obtain a key from the [1inch Business Portal](https://business.1inch.com/portal).
+
+Pass it as:
+
+`Authorization: Bearer <YOUR_API_KEY>`
+
+How you set this depends on the client:
+
+- **Cursor** (`.cursor/mcp.json`): `headers.Authorization`
+- **VS Code** (`.vscode/mcp.json`): `headers.Authorization`
+- **Claude Code**: `claude mcp add --header "Authorization: Bearer ..."`
+- **Claude Desktop** (stdio via supergateway): add `--header` `Authorization: Bearer ...` to the supergateway args **after** `--streamableHttp` and URL (see product docs).
+
+## OAuth
+
+If the user calls an authenticated tool without a key, MCP clients that support OAuth can start a browser login against the 1inch Business Portal. After login, tools work for that session.
+
+Protected tools (including the optional `debug` log lookup) need a **non-anonymous** session: a **Bearer API key** and/or **OAuth** as supported by the gateway, plus (for `debug`) organization context for log scoping. The `debug` tool is only available when the server registers it; see [TOOLS.md](TOOLS.md).
+
+## Stdio bridging (Claude Desktop and similar)
+
+When the client only supports stdio:
+
+```bash
+npx -y supergateway \
+  --streamableHttp https://api.1inch.com/mcp/protocol \
+  --outputTransport stdio
+```
+
+With API key:
+
+```bash
+npx -y supergateway \
+  --streamableHttp https://api.1inch.com/mcp/protocol \
+  --header "Authorization: Bearer YOUR_API_KEY" \
+  --outputTransport stdio
+```
+
+Use **absolute paths** to `npx` and ensure `PATH` in the MCP server `env` includes your Node binary directory.
+
+## Security
+
+- Never commit API keys to repositories or skills.
+- Treat skills that mention keys as **user-supplied configuration**, not embedded secrets.

+# 1inch MCP tools -- reference
+
+Production endpoint: `https://api.1inch.com/mcp/protocol`.
+
+Tools expose **safety hints** to clients: read-only tools use `readOnlyHint`; tools that can change on-chain or remote state use `destructiveHint`.
+
+## Public tools
+
+### `search`
+
+Search documentation, API references, and SDK guides.
+
+| Parameter      | Type    | Required | Notes                      |
+| -------------- | ------- | -------- | -------------------------- |
+| `query`        | string  | Yes      | Search string              |
+| `limit`        | number  | No       | 1-100, page size           |
+| `page`         | number  | No       | 1-based pagination         |
+| `include_body` | boolean | No       | Include full document body |
+
+### `list_examples`
+
+No parameters. Returns available SDK example identifiers.
+
+### `get_example`
+
+| Parameter | Type   | Required | Notes                                 |
+| --------- | ------ | -------- | ------------------------------------- |
+| `name`    | string | Yes      | Example id from `list_examples`       |
+| `file`    | string | No       | Specific file path inside the example |
+
+## Authenticated tools
+
+Require API key or OAuth session. See [AUTH.md](AUTH.md).
+
+### `swap`
+
+Token swaps (classic, Fusion, cross-chain). Supports quote-only mode (`quoteOnly: true`), execution (returns txs or typed data to sign), and submission (`signedOrder` / `orderHash` for Fusion/cross-chain).
+
+Key parameters: `src`, `dst`, `amount`, `chain`, `from`, optional `quoteOnly`, `preferredType`, `dstChain`, `slippage`, `signedOrder`, `orderHash`.
+
+Prefer the product docs for the full parameter matrix and flows.
+
+### `orderbook`
+
+Limit orders via Orderbook API v4.1. **action** is required: `build` | `create` | `list` | `cancel`.
+
+Typical flow: `build` -> user signs typed data -> `create` with signature.
+
+### `product_api`
+
+Proxy to 1inch product REST APIs.
+
+| Parameter | Type              | Required | Notes                                 |
+| --------- | ----------------- | -------- | ------------------------------------- |
+| `method`  | `"GET"` or `"POST"` | No     | Default `GET`                         |
+| `path`    | string            | Yes      | API path (e.g. portfolio, price, gas) |
+| `query`   | object            | No       | Query string map                      |
+| `body`    | object            | No       | JSON body for POST                    |
+
+Because the tool can perform writes via POST, it is marked **destructive** at the MCP layer even when `method` is GET.
+
+### `debug`
+
+**Optional** — the server only registers this tool when Grafana Loki integration is enabled. It does not appear in `tools/list` otherwise.
+
+Org-scoped production debugging: look up application logs in Loki. Requires the same **authenticated** access as other protected tools (Bearer and/or OAuth per gateway); organization scope comes from the gateway context.
+
+**Modes:** (1) pass `requestId` (e.g. `x-request-id`) with optional `startTime` / `endTime` (defaults: 24h lookback to `endTime` or now). (2) omit `requestId` and pass `startTime` and `endTime` (RFC3339), with optional `logLevel` (`info` | `warn` | `error`) and `limit` (1–100, default 50).
