Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.
Tools: get_pricing inspect_endpoint
get_pricing | MCP Canary plans, monthly prices (in cents), and limits, plus the free trial. The trial needs no payment and starts on the first monitor write. params: none |
inspect_endpoint | Connects to a remote MCP endpoint (Streamable HTTP, then legacy SSE), lists its tools, and classifies each tool's side effects from its MCP hints. Never calls a tool on the target. A target problem is status=failed with a stable failure code (e.g. TARGET_UNAVAILABLE, TARGET_AUTH_FAILED, MCP_PROTOCOL_ERROR). Private and loopback addresses are rejected. params: url*, headers |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json. Opt-out: how or hello@youraitools.co.
