What is the Emem — Earth Memory Protocol MCP Server?

Content-addressed, ed25519-signed memory of every place on Earth. Apache-2.0, no keys for reads.

The short version

One click from the registry page adds the server to a supporting host. Nothing else is required: reads take no key, no account and no signup, so the first call works before you have decided whether to trust us. That is the point, and it is checkable rather than promised, because every answer carries an ed25519 receipt that verifies against the responder's published key rather than its word.
