Install Power Automate MCP Server by Flow Studio in Goose

What you need first

• Goose, installed.
• Nothing else: the server runs on its publisher's machines and Goose connects to it.
• Your own value for YOUR_X_API_KEY.

Steps

1. Open ~/.config/goose/config.yaml. On Windows it is %APPDATA%\Block\goose\config\config.yaml.
2. Add this entry. If the file already has extensions, add only the entry inside it.

extensions:
  "flowstudio-mcp":
    type: streamable_http
    name: "flowstudio-mcp"
    enabled: true
    uri: "https://mcp.flowstudio.app/mcp"
    headers: { "x-api-key": "YOUR_X_API_KEY" }
    env_keys: []
    envs: {}
    timeout: 300

3. Replace YOUR_X_API_KEY with your own value.
4. Save the file and start a new Goose session.

Check it worked

Ask Goose: List the tools of flowstudio-mcp.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Goose asks, or check the value in place of the placeholder.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid YAML any more. Check that the entry is indented like the lines around it.
