Current tools (5)

lookup_serverReads the board's latest daily probe of one server in the official MCP registry: status, how a client gets access, the exact Claude token cost of its tool definitions, tool count, latency and the most expensive tools. Instant, no connection to the server. Use it when the server is in the registry; use search_servers when you do not know its name, and check_server to probe a URL that is not in the
params: nameOrUrl*
search_serversFinds servers on the board by words in their name, title, description or host, with optional filters, sorted by exact Claude token cost (highest first) by default. With no query and no filter it ranks the whole board, so page 1 is the most expensive servers in the registry and sort=claude-asc the cheapest. Use it to discover servers or to rank them by cost; use lookup_server once you have a name,
params: query, status, sort, page, cursor
check_serverConnects to an MCP server URL now (initialize and tools/list, 10 s timeout) and reports status, protocol, how a client gets access, tool names and the token cost of the tool definitions: exact in Claude when the counter is available, else an estimate from the schema size. Use it for a URL that is not in the official registry, or to see the state this minute; for a registry server prefer lookup_ser
params: url*
compare_serversPuts two to five registry servers next to each other from the board's latest daily probe: status, how a client gets in, tool count, token cost (exact in Claude when counted, else the estimate), share of a 200k window and initialize latency, with the cheapest, the most expensive and the spread. Use it to choose between servers that do the same job; use lookup_server for the full record of one serve
params: servers*, format
registry_summaryAggregates of the latest daily run over the whole official MCP registry: how many servers answer and why the rest do not, token cost percentiles and the exact-to-estimate ratio, how servers authenticate, protocol versions, transports, the heaviest servers and the biggest publishers. Use it for the state of the registry as a whole; use lookup_server or search_servers for one server. No input; the a

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.
