Full AI agent tool schema audit API (MCP and function calling). Full audit of an agent tool list (tools array or public remote MCP URL): every schema issue per provider (OpenAI, Anthropic, Gemini, Bedrock, MCP; strict mode opt-in) with JSON path and source link, rewritten definitions per provider, confusable tool pairs with distinguishing terms and fix hints, description and poisoning lints, per-tool fingerprints and a pin.

MCP server checker API. Preflight a public remote MCP server before connecting or paying: does it answer an MCP initialize, which protocol version, sign-in method (OAuth metadata), x402 payment terms, latency, tool count, token cost, provider compatibility, poisoning patterns in tools and instructions, and a grade with issues. Lists tools only, never calls them. Blocked or unresolvable URLs are never charged.

Check an agent tool list (tools array or public remote MCP URL): grade A-F, estimated tokens per tool and total, compatible yes/no for OpenAI, Anthropic, Gemini, Bedrock and MCP, the top confusable tool pairs, basic poisoning count and a pin (set_id) for later diffs. Bad input or an unreachable URL: never charged.

HMAC-SHA256 signed webhook on tools/list fingerprint or grade changes (and unreachable/recovered). Returns watch_id, the signing secret (shown once) and the baseline. Never charged for unreachable or blocked URLs or a full watch list. Search intents: mcp server monitoring, mcp uptime, mcp tool change alerts, mcp webhook alerts, watch mcp server, mcp drift monitor.

MCP server monitoring API (24h checks, 30 days). Register a public remote MCP server URL and an https webhook: ToolFit re-audits the server every 24 hours for 30 days and POSTs an HMAC-SHA256 signed JSON notification when its tools/list fingerprint (pin) or grade changes, or it becomes unreachable or recovers. Returns watch_id, the signing secret (shown once) and the baseline. Unreachable URLs, blocked URLs or webhooks and a full watch list are never charged.

AI agent tool change detector API (MCP tool diff). Compare an agent tool list now (tools array or public remote MCP URL) with a pin from an earlier ToolFit call (or a baseline array): removed or added tools, changed descriptions with a word diff and new poisoning findings, removed or newly required params, type and enum changes, annotation changes. Verdict: unchanged, compatible, review, suspicious or breaking.

How these numbers are made
Each listing is called on a schedule without paying. Listings with usage or a verified owner are checked about every 30 minutes, others about every 6 hours. Uptime is the share of passing checks over 30 days, averaged across this provider's listings. Trust scores follow the published method. The figures on this page can be a few minutes behind the latest checks, and listings hidden after review aren't counted.
