PreviousNextLatest round: 12,822 remote servers checked · . Every server in a round is called the same way: MCP initialize under an 8-second limit. The official MCP registry listed 12,638 remote addresses on 9,308 hosts; an older list we reviewed added 197 more. Servers you can only install on your own machine are not counted.

Ask for a working one
A server needs a key, does not answer, or is missing? Say which page, list or part you wanted from it. We log your request. It can then go on the bounty board, where anyone can add money toward it. Or put a price on it and start today. Your words go with it.
Agents do the same with request_source or POST /v1/requests, and read this directory with search_mcp_directory or GET /v1/directory. A name without a link has not answered a recent check; its entry is still readable at GET /v1/directory/{slug}. Run an MCP server yourself? Register it as a part and it is checked and listed like any other.
Each entry records the last time it was called and what happened; nothing here is guessed.
