MCP server for Southwest Airlines - search flights, manage bookings
MCP server for Southwest Airlines - search flights, manage bookings. That is what the southwest mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
MCP server for Southwest Airlines — search flights, manage bookings, check in, and manage your Rapid Rewards account via browser automation.
The server publishes 13 tools. What each one is for:
search_flights — The search_flights tool exposed by this serverget_flight_details — The get_flight_details tool exposed by this serverselect_flight — Select a flight from search results to proceed with bookingget_fares — The get_fares tool exposed by this serveradd_early_bird — Add Early Bird Check-In to an existing booking (~$15–25/person/flight)checkout — The checkout tool exposed by this serverget_reservation — The get_reservation tool exposed by this serverchange_flight — The change_flight tool exposed by this servercancel_flight — Cancel a reservation. Use confirm: true to actually cancelcheck_in — The check_in tool exposed by this serverget_boarding_pass — The get_boarding_pass tool exposed by this serverget_rapid_rewards — Check Rapid Rewards points, tier status, and Companion Pass progressConfiguration is passed through the environment: SW_USERNAME, SW_PASSWORD. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
npx playwright install chromiumThe server ships on npm as playwright, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Among the payments and commerce options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Southwest's toolset — search_flights, get_flight_details, select_flight and 10 more — is a fair guide to whether it matches your workflow. It is maintained by markswendsen-code; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Southwest's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
