Goose

Goose takes Grounder as a remote extension in config.yaml and opens Grounder’s sign-in screen when a session starts.

extensions:
  grounder:
    enabled: true
    type: streamable_http
    name: grounder
    uri: https://api.grounder.net/mcp
    timeout: 300
# sign in when a session starts

Goose has its own web-search skill, so you may need to ask for Grounder by name.
