Weather MCP servers

Which weather MCP servers actually answer?

Of 245 servers in the official MCP registry that mention Weather, we checked 130 remote endpoints on 2026-10-04: 84 answered the MCP handshake, 20 answered but asked for sign-in or payment first, and 26 did not complete it. 106 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.
