Crypto and blockchain MCP servers

Which blockchain MCP servers actually answer?

Of 92 servers in the official MCP registry that mention Crypto and blockchain, we checked 38 remote endpoints on 2026-10-04: 23 answered the MCP handshake, 10 answered but asked for sign-in or payment first, and 5 did not complete it. 50 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.

Ranked by our checks and repository activity, not by votes. How we check.
