audit_tools
Audit a tool list (ToolFit)
Check the tool definitions an agent loads, before they cost tokens or fail: estimated tokens per tool, schema errors per provider (OpenAI, Anthropic, Gemini, Bedrock, MCP; add openai_strict for strict mode) with JSON paths and fixed definitions, tool pairs models will confuse with fix hints, basic poisoning patterns, a grade and a pin (set_id) for diff_tools. Pass "tools" (array in any common format) or "url" (public remote MCP server; tools are listed, never called). level "lite" returns the summary only. Free: 20 calls/day per IP (shared with diff_tools), then $0.003 lite / $0.01 full via x402 or credits.

diff_tools
Diff a tool list against a pin (ToolFit)
What changed in a tool list since you approved it? Compares "tools" or "url" now with "pin" (set_id from audit_tools/diff_tools) or "baseline" (earlier definitions). Each change is labeled breaking (removed tool or param, new required param, type or enum removal), suspicious (new text with injection patterns or hidden characters), review (description, title, annotation or new tool) or additive; descriptions come with before/after text and a word diff. Returns a new pin. Free: 20 calls/day per IP (shared with audit_tools), then $0.002 via x402 or credits.

check_mcp_server
Preflight a remote MCP server (MCPCheck)
Does this remote MCP server work, and is it worth connecting or paying for? Sends initialize and tools/list only (never calls a tool) and reports reachability, protocol version, sign-in method (OAuth protected-resource metadata), x402 payment terms if it asks for payment, latency, tool count and token cost, provider compatibility, poisoning patterns in tools and server instructions, issues and a grade A-F, plus a pin for later diffs. https public hosts only. Free: 10 checks/day per IP, then $0.005 via x402 or credits.

watch_mcp_server
Watch a remote MCP server for changes (ToolFit)
Hosted watch (paid only; this MCP call validates and returns how to pay): ToolFit re-audits a public remote MCP server every 24 h ($0.25) or 6 h ($0.60) for 30 days and POSTs an HMAC-SHA256 signed JSON webhook to your https endpoint when its tools/list fingerprint or grade changes, or it goes unreachable or recovers. Pay at POST /v1/watch or /v1/watch/6h with x402 or a credits key; the response has watch_id and the signing secret (shown once).
