Authentication

This server uses browser automation and stores session cookies locally. To authenticate:

1. Call the login tool — it opens aa.com in a browser window
2. Log in manually with your AAdvantage credentials
3. Call status to verify and save the session

Sessions are saved to ~/.striderlabs/american/ and reused across invocations. You typically only need to log in once until the session expires.

Example Workflow

User: Search for flights from DFW to JFK next Friday

Agent:
1. search_flights { origin: "DFW", destination: "JFK", departureDate: "2025-07-11" }
2. get_flight_details { flightId: "0" }
3. select_flight { outboundFlightId: "0" }
4. get_seat_map {}
5. select_seats { seats: ["14A"] }
6. add_bags { bags: 1 }
7. checkout {}  → preview
8. checkout { confirm: true }  → booking confirmed

Safety Gates

Destructive or financial actions require explicit confirmation:

• checkout — pass confirm: true only after user confirms the purchase
• cancel_trip — pass confirm: true only after user confirms the cancellation

Without confirm: true, these tools return a preview instead of taking action.

Environment Variables

Optional — credentials can be provided via environment variables for automated workflows:

Variable	Description
AA_USERNAME	AAdvantage number or email
AA_PASSWORD	Account password

When set, the server will attempt auto-login on first use.

Session Storage

Cookies and session info are stored at:

~/.striderlabs/american/
├── cookies.json    # Browser session cookies
└── session.json    # Account info cache

To reset authentication: call logout or delete this directory.
