"""Connect to the API-key-backed OAuth server.

Running this triggers the OAuth flow: a browser window opens to the server's
consent page. Enter any non-empty key (the demo server accepts anything) and the
connection completes. The `list_files` tool then runs with the key the server
recovered from your token.

To run (with server.py already running):
    python client.py
