Trust report

Scanned 2026-07-09 · MCP 2025-11-25

Scored by MCP Vouch against the OWASP MCP Top 10. SKIP applies to HTTP-only checks not relevant for stdio servers and is excluded from the score.

Is clinicaltrialsgov-mcp-server safe to use?

clinicaltrialsgov-mcp-server scores 81/100 — grade B, which is a solid posture with a few gaps worth reading. It passes 5 of the 8 OWASP MCP Top-10 checks that apply to it, with Insufficient Input Validation, Inadequate Rate Limiting, and Supply Chain Risk returning a warning rather than a pass. 2 further checks do not apply to this server's transport and are excluded from the score entirely — skipped is not the same as failed. This is what the scanner found on 2026-07-09, not a guarantee. Re-run it yourself with `npx mcpr scan`.

What a grade B means, the ten checks behind it, and the point maths are all on how we score MCP server trust.
