Automate Delta flight searches, bookings, and SkyMiles management.
@striderlabs/mcp-delta
MCP server for Delta Air Lines — let AI agents search flights, select seats, manage bookings, check in, get boarding passes, and check SkyMiles balance via browser automation.
Built by Strider Labs.
Features
- 17 tools covering the full Delta booking and travel management workflow
- Playwright browser automation with stealth patches to avoid bot detection
- Session persistence via cookies at
~/.striderlabs/delta/cookies.json - Human-like behavior — random delays, realistic user agent, locale/timezone spoofing
- SkyMiles integration — check balance, Medallion status, and recent activity
- Confirmation gates for checkout to prevent accidental bookings
- JSON responses for easy parsing by AI agents

{
"mcpServers": {
"delta": {
"command": "striderlabs-mcp-delta"
}
}
}
Or with npx:
{

Authentication
Some tools (SkyMiles balance, booking management, check-in) require a Delta SkyMiles account. The server persists your session cookies at ~/.striderlabs/delta/cookies.json.
Login flow:
- Ask the AI agent to run
login - Open the returned URL in your browser
- Log in to your Delta SkyMiles account
- Run
statusto verify the session was saved
Flight search and flight status work without authentication.
Example Workflows
Book a Flight
1. search_flights(origin="ATL", destination="LAX", departureDate="2025-07-15")
2. get_flight_details(flightId="0")
3. select_flight(outboundFlightId="0")
4. get_seat_map()
5. select_seats(seats=["24A"])
6. add_bags(bags=1)
7. checkout() ← returns preview
8. checkout(confirm=true) ← completes purchase (needs explicit user confirmation)
Check In
1. check_in(confirmationNumber="ABC123", lastName="Smith")
2. get_boarding_pass(confirmationNumber="ABC123", lastName="Smith")
Monitor a Flight
1. get_flight_status(flightNumber="DL 123")
Manage SkyMiles
1. login()
2. get_skymiles()
Safety
The checkout tool requires confirm: true to actually complete a purchase. Without it, the tool returns a preview of the booking details. Never set confirm: true without explicit user confirmation.
The manage_booking cancel action will prompt you to confirm on the Delta website before any cancellation is finalized.
Session Storage
Cookies and session info are stored at:
~/.striderlabs/delta/cookies.json~/.striderlabs/delta/session.json
Environment Variables
No environment variables are required. Credentials are managed via the browser session stored in ~/.striderlabs/delta/.
Development
git clone https://github.com/markswendsen-code/mcp-delta
