trvl-mcp

AI travel agent MCP server. 1 smart travel MCP tool — a natural-language router that advertises a single tool (~378 tokens of context) instead of a full per-domain tool list (~33,500 tokens): a ~98.9% smaller context footprint. Covers flights, hotels, ground transport, price alerts, and more, dispatched by natural language. No personal API keys are required for default search.

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.

What's included

• 1 smart travel MCP tool — natural-language router; advertises one tool (~378 tokens) instead of a full per-domain list (~33,500), so your AI's context window stays lean. Older clients that call legacy per-domain tool names still work, reachable as legacy-compatible capabilities via the intent field (set TRVL_MCP_TOOL_MODE=legacy to advertise the full list for clients that require it).
• Default flight search (Google Flights, Kiwi, Skiplagged), with solo or opt-in AFKLM and low-cost-carrier integrations
• Criteria-first accommodation search plus hotel discovery (Google Hotels, Booking.com, Airbnb, Hostelworld, Trivago, HomeToGo) and verified room/detail flows for shortlisted candidates
• Ground transport (buses, trains, ferries — 22 providers)
• Destination intelligence (weather, safety, holidays, events)
• Trip planning and price alerts
• Travel hacks detection (36 detectors)
