trvl-mcp

AI travel agent MCP server. 1 smart tool, not 66 — advertises a single travel router (~378 tokens of context) instead of 66 separate tools (~33,500 tokens), a 98.9% smaller context footprint. Covers flights, hotels, ground transport, price alerts, and more, dispatched by natural language. No API keys required for default discovery.

Hotel trust rule: use search_accommodations for traveller-facing stay recommendations. Raw search_hotels prices are lead-in discovery prices. Before ranking a final trip cost or telling a user what to book, use criteria-matched room/apartment offers from search_accommodations or verify shortlisted hotels with room/detail/provider totals (search_hotels_with_details, hotel_rooms, or trvl serpapi when SERPAPI_KEY is configured). trvl provides booking handoff links; it does not book, hold, or guarantee hotel rates.
