Install PDF/UA accessibility check (veraPDF) with measured auto-fix in Goose

What you need first

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

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:
  "pdfua-check":
    type: streamable_http
    name: "pdfua-check"
    enabled: true
    uri: "https://pdfua-check.onrender.com/mcp"
    headers: {}
    env_keys: []
    envs: {}
    timeout: 300

3. Save the file and start a new Goose session.

Check it worked

Ask Goose: List the tools of pdfua-check.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Goose asks.

Nothing changes after a restart

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