Free MCP Protocol Audit - identify tool discovery, timeout, and schema issues

🎯 Free MCP Server Audit Offer

Hey @0x4m4 — HexStrike AI is an impressive project (150+ security tools exposed as MCP tools is a genuinely powerful concept), and I can see from the issue tracker you're dealing with several recurring MCP protocol-level problems:

• Antigravity Issue #128 / Open-Webui Integration #127 — MCP integration failures where tools aren't discovered ("0 resource" output)
• Long tokens on initialization #138 — 400K+ tokens on initialization, causing providers to reject the connection
• Request failed: 500 Server Error: INTERNAL SERVER ERROR for url: http://127.0.0.1:8888/api/visual/summary-report #146 — 500 errors on tool endpoints
• Not all tools available #147 — "Not all tools available" on fresh installs

These all point to MCP protocol-level issues: tool listing schema validation, initialization handshake compliance, and error boundary completeness.

What I'm offering

I run the MCP Auditor — an automated testing & certification platform specifically for MCP servers. It runs a full conformance suite:

1. Protocol handshake — validates initialize / initialized flow per the spec
2. Tool discovery — checks tools/list returns complete, valid JSON-RPC responses
3. Schema validation — verifies tool input schemas are well-formed and not bloated (critical for the 400K token issue)
4. Error handling — tests that tool failures return proper JSON-RPC errors, not raw HTTP 500s
5. Latency profiling — measures round-trip times per tool across all 150+ tools

I'm offering one free comprehensive audit — I'll run HexStrike through the full suite and send you the report with findings and specific code-level recommendations for each issue identified.

Why this matters for HexStrike specifically

Integration with Cline, Claude Code, Open-WebUI, and other MCP clients (all actively requested in your issues) depends on strict protocol compliance. Even minor deviations — a missing isError field, oversized initialization response, or non-compliant schema — can silently break client connections.

How to claim

No strings attached. Just reply here or DM, and I'll set up the audit. The full report comes as a PDF with PASS/FAIL per test, latency data, and concrete code suggestions.

Alternatively, you can self-serve by submitting your server URL at api.gadgethumans.com/mcp-audit and mention this issue for a waived fee.

Cheers,
— Scotty

@coclock Thanks for the /attempt! Your approach looks solid — the missing types/exports field is exactly the root cause I identified in the audit.

I'd be happy to collaborate on this. A few things I noticed during the audit that might help:

1. The package.json types field points to ./dist/index.d.ts but the emitted file is at ./dist/src/index.d.ts — that mismatch is the main issue.
2. There are also some schema validation gaps in the tool parameter definitions that I can share.

Want to coordinate on the fix? I can handle the schema cleanup if you tackle the build config. Happy to review your PR once it's up.

Also — if you're building MCP servers yourself, I've been running automated audits on them using the GadgetHumans MCP Auditor. The free tier catches these exact kinds of issues.
