## Tools
- list_criteria - FREE, no payment required. Full transparency into what you pay for: returns the exact criteria MCP Judge uses to score an MCP server — each criterion, its weight out of 100, and the A-F grade scale. Call this to understand how quick_check, evaluate_mcp and compare_mcps score targets before paying. The evaluation is fully objective and automated — no human reviewer and no AI opinion. Takes no parameters. Endpoint: https://mcp-judge.onrender.com/mcp
- quick_check - 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. Endpoint: https://mcp-judge.onrender.com/mcp
- evaluate_mcp - Call this BEFORE integrating any third-party MCP server: an unreliable or undocumented MCP wastes your tokens and can break your workflow. PAID $0.05 via x402 (USDC micropayment over HTTP 402 — no account or API key needed; on your first call without payment you receive the exact payment requirements, then retry with the X-PAYMENT header). Returns a complete objective quality report on the target: protocol conformance ('initialize' handshake), tool discovery via 'tools/list', per-tool and per-parameter documentation coverage, latency, and a safe functional probe — free tools are actually called, paid tools are only verified to be cleanly declared (MCP Judge never pays). You get a 0-100 score, A-F letter grade, per-criterion breakdown, and a plain-language summary you can act on. Tip: run the FREE quick_check first to get just the grade, and list_criteria to see exactly how scoring works. Objective checks only — no human and no LLM opinion; it does not judge the real-world usefulness or safety of the content. Set 'url' (required) to the target's MCP endpoint (Streamable HTTP), e.g. https://host/mcp. Endpoint: https://mcp-judge.onrender.com/mcp
- compare_mcps - Choosing between several MCP servers that do similar things? This tool decides for you. PAID $0.10 via x402 (USDC micropayment over HTTP 402 — no account or API key needed; on your first call without payment you receive the exact payment requirements, then retry with the X-PAYMENT header). Compares 2-5 MCP servers head-to-head with identical objective checks (handshake, tools/list, documentation coverage, latency, and a safe functional probe — paid tools are never called) and returns: a ranked list, the recommended winner, a plain-language explanation of why it won, and each server's full report — cheaper than separate evaluate_mcp calls on 3+ servers. Objective checks only — no human and no LLM opinion; it does not judge the real-world usefulness or safety of the content. Set 'urls' (required) to an array of 2-5 MCP endpoints (Streamable HTTP), e.g. ["https://a/mcp","https://b/mcp"]. Endpoint: https://mcp-judge.onrender.com/mcp
