FREE, no payment required. Instant trust check of any MCP server: returns only the 0-100 score, A-F grade, tool count, latency and a one-line verdict — no detailed report. Use this FIRST, before integrating any third-party MCP server, to see at a glance whether it is technically trustworthy; an unreliable MCP wastes your tokens and can break your workflow. For the full actionable report (per-tool documentation coverage, functional probe results, score breakdown, plain-language summary) call evaluate_mcp; to pick between alternatives call compare_mcps. Set 'url' (required) to the target's MCP endpoint (Streamable HTTP), e.g. https://host/mcp.
