How it works

Running in three steps.

  1. 01

    Create the address

    Make it in settings, then share it or issue a key for it.

  2. 02

    Connect the client

    Point an MCP client at the server, sign in, approve it.

  3. 03

    Keep the reins

    Its role decides the tools. Remove the app whenever you like.
