ToolFit by YourAITools
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.
