@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

Tools

Installation

npm install -g @striderlabs/mcp-delta
npx playwright install chromium

Claude Desktop Integration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "delta": {
      "command": "striderlabs-mcp-delta"
    }
  }
}

Or with npx:

{
  "mcpServers": {
    "delta": {
      "command": "npx",
      "args": ["-y", "@striderlabs/mcp-delta"]
    }
  }
}

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:

1. Ask the AI agent to run login
2. Open the returned URL in your browser
3. Log in to your Delta SkyMiles account
4. Run status to 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/.
