Variflight Mcp
VariFlight's official server gives you direct access to their aviation data API with eight tools covering the typical flight search workflow. You can query direct flights by route or flight number, find connecting options between cities, check real-time aircraft positions by tail number, and pull 3-day airport weather forecasts. The flight happiness index tool returns comfort metrics like punctuality stats, aircraft config, and onboard amenities. Two pricing tools provide either a natural language summary with recommendations or raw cabin-level fare data. Requires a VariFlight API key from their MCP portal. Reach for this when building travel assistants or flight tracking features that need comprehensive aviation data beyond basic schedules.
