A public, read-only change history of remote MCP servers listed in the official MCP Registry (registry.modelcontextprotocol.io). For each server ToolFit records what its tools/list returned and what changed since the previous listing: tools added or removed, description and parameter changes, and the ToolFit grade over time.
4039 servers with history · 9193 listings so far · registry entries in the last full sync: 49510. 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.

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.
