lookup_serverLatest 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.search_serversFind servers by words in name, title, description or host, with optional filters, sorted by exact Claude token cost by default. Returns up to 20 servers per page; page numbers go to 20, after that pass the `next` cursor from the previous answer.check_serverConnects 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.registry_summaryAggregates of the latest daily run: how many servers answer, token cost percentiles, protocol versions, heaviest servers.
