Slack MCP servers

Which Slack MCP servers actually answer?

Of 54 servers in the official MCP registry that mention Slack, we checked 25 remote endpoints on 2026-10-04: 8 answered the MCP handshake, 15 answered but asked for sign-in or payment first, and 2 did not complete it. 25 run on your own machine and cannot be checked from outside.

What this does not tell you: whether a server is safe, or whether its tools do what they say. An answer to the handshake proves the endpoint is up, nothing more.
