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: check_defects
check_defects | Before using an MCP server or an API operation, ask what is known to be wrong with it. Takes one identity: an MCP registry entry (io.github.owner/repo), a deployment URL, an OpenAPI document URL, or a host. Answers one of three things, and they are three rather than two: `defects_known` - open records, each carrying the check that found it, which you can rerun yourself; `examined_nothing_open` - t params: tool* |
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.
