Install Fatsecret in Goose

What you need first

• Goose, installed.
• uv, which gives the uvx command the server starts with.
• Your own values for YOUR_FATSECRET_CONSUMER_KEY,YOUR_FATSECRET_CONSUMER_SECRET,YOUR_FATSECRET_MCP_SIGNING_KEY,YOUR_FATSECRET_MCP_USERS.

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:
  "fatsecret-mcp":
    type: stdio
    name: "fatsecret-mcp"
    enabled: true
    cmd: "uvx"
    args: ["fatsecret-mcp==0.1.0"]
    env_keys: []
    envs: { "FATSECRET_CONSUMER_KEY": "YOUR_FATSECRET_CONSUMER_KEY", "FATSECRET_CONSUMER_SECRET": "YOUR_FATSECRET_CONSUMER_SECRET", "FATSECRET_MCP_SIGNING_KEY": "YOUR_FATSECRET_MCP_SIGNING_KEY", "FATSECRET_MCP_USERS": "YOUR_FATSECRET_MCP_USERS" }
    timeout: 300

3. Replace YOUR_FATSECRET_CONSUMER_KEY,YOUR_FATSECRET_CONSUMER_SECRET,YOUR_FATSECRET_MCP_SIGNING_KEY,YOUR_FATSECRET_MCP_USERS with your own values.
4. Save the file and start a new Goose session.

Check it worked

Ask Goose: List the tools of fatsecret-mcp.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that Goose sees. Install it, or write the full path of uvx in the config.

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.
