Agent harnesses

Connect Goose

AAIF (ex-Block) · Apache-2.0

SupportedOAuth 2.1API key

The open-source agent where every capability is an MCP extension — remote servers plug into the same slot as built-ins.

1 · Choose the MCPs to connect

2 · How should it authenticate?

3 · Add to ~/.config/goose/config.yaml

extensions:
  deepinsights-mospi:
    enabled: true
    type: streamable_http
    name: deepinsights-mospi
    uri: https://marketplace-gateway-pef65a33ta-el.a.run.app/mospi/mcp
  1. 1.OAuth: Goose opens a browser sign-in on first use (its OAuth flow still has rough edges — fall back to an API key if it loops).
  2. 2.API key: replace mk_… with your personal key, then restart Goose.

4 · Create it as an app

Save this harness + MCP setup to your account. You get a workbench with a live test chat over the combined tool surface — the exact gateway endpoints, auth and tools Goose will use, metered to your own quota.

5 · Or test each MCP on its own

Each playground's Chat and Tools pages exercise exactly the tools your harness will see — same servers, same gateway. Verify a query there first, then run it from Goose.
