Payments MCP servers

Which payment MCP servers actually answer?

Of 760 servers in the official MCP registry that mention Payments, we checked 430 remote endpoints on 2026-10-04: 205 answered the MCP handshake, 76 answered but asked for sign-in or payment first, and 149 did not complete it. 256 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.
