What it can do
| Tool | What it says it does |
|---|---|
check_server | Connects 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… |
compare_servers | Puts 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… |
lookup_server | Reads 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… |
registry_summary | Aggregates 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… |
search_servers | Finds 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… |
In its maker's words
Health and token cost of every remote MCP registry server, probed daily. Look up, search, or probe.
