grade_mcp_server

Independently grade an MCP server (A–F) BEFORE connecting an agent to it. Returns spec-conformance, security (OWASP MCP Top 10), reliability, tool-hygiene and transparency sub-scores plus a connect/caution/avoid recommendation. Audited by wmcp.sh; the grade is free and never for sale.

check_mcp_drift

Check whether an MCP server's tool definitions have changed since it was last trusted (rug-pull / schema-drift detection, the CVE-2025-54136 class). Returns how long the tool surface has been stable, how many times it has changed, and the last change. Use after approval to detect post-trust mutation

verify_before_execute

Verify an MCP server immediately BEFORE you execute any of its tools. Combines the continuously-watched trust grade and live drift status into a single connect/caution/avoid verdict (ok | caution | drifted | failing | ungraded), so you can gate the call in one step. Free, read-tier. The grade is ind

How we measure →

What this means. This server responded to the MCP handshake and listed its tools without authentication. The schema fingerprint lets us flag if tool signatures silently change (schema drift) between checks.
