Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_server | Connects to an MCP server URL now (initialize and tools/list, no credentials, 10 s timeout) and reports status, protocol, tools and the token cost of the tool definitions: exact in Claude when the counter is available, else an estimate from the schema size. For registry servers prefer lookup_server. | Not declared |
| lookup_server | Latest probe of one server from the official MCP registry: status, protocol, tool count, exact token cost of its tool definitions in Claude, latency. Accepts the registry name (io.github.owner/name) or the server URL. | Not declared |
| registry_summary | Aggregates of the latest daily run: how many servers answer, token cost percentiles, protocol versions, heaviest servers. | Not declared |
| search_servers | Find servers by words in name, title, description or host, with optional filters, sorted by token cost by default. Returns up to 20 servers per page. | Not declared |
