MCP clients

Connect Ken to goose with MCP

goose connects to Ken's remote MCP server as a Remote Extension (Streamable HTTP). Run goose configure, choose Add Extension, name it ken and enter Ken's server URL as the endpoint, then sign in to Ken in your browser. A Ken API key header also works.

How Do You Connect Ken to goose?

In short Add https://mcp.ken.so/mcp as a remote MCP server in goose, then sign in to Ken in your browser.

  1. Start goose configure

    Run this in your terminal and choose Add Extension.

    goose configure

    goose registers itself with Ken and opens the Ken sign-in in your browser when it first connects. Your browser opens the Ken sign-in. Sign in with the account you use in the Ken app, then select Allow access on the Ken approval screen. You never paste a client ID or secret.

    Create a key in the Ken app under Settings > Integrations > API Keys. In goose configure, answer Yes to Would you like to add custom headers and add an Authorization header with the value Bearer and your key. In config.yaml, the extension entry looks like this.

    extensions:
      ken:
        name: ken
        type: streamable_http
        uri: https://mcp.ken.so/mcp
        headers:
          Authorization: "Bearer <KEN_API_KEY>"
        enabled: true
        timeout: 300
