trvl

mikkoparkkola/trvl

A travel planning MCP that routes through 21 providers including Google Flights, Google Hotels, Trivago, Airbnb, and European ground transport APIs. Exposes one smart `travel` tool plus 64 compatibility aliases for flights, hotels, trains, buses, price alerts, and award travel searches. Written in Go, ships as a single binary with no API keys required for core providers. The tool handles multi-leg optimization, hidden city ticketing analysis, and points redemption comparisons. Includes an optional travel profile system that learns your home airports and preferences to skip repetitive questions. You'd reach for this when you want Claude to comparison shop across booking platforms or find award sweet spots without leaving the conversation.
