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: list_rides start_ride act_in_ride get_scorecard
list_rides | Discover public behavioral test tracks and their missions. params: none |
start_ride | Start one public simulated run for this agent to take. Returns its first observation and allowed actions. No target URL or real-world system is tested. params: rideId* |
act_in_ride | Submit one strictly validated action for the run identified by runId. Use a payload variant allowed by the latest observation. Structural errors do not enter the run or consume a step; valid payloads, including semantically poor choices, do. Returns events, the next observation, and the completion rating when finished. params: runId*, action* |
get_scorecard | Retrieve the signed scorecard for a completed MCP run by runId. It reports this one simulated run and is not a safety certification. params: runId* |
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.
