Travel Tools MCP Server

MCP server that helps travel agents cover the full trip-quoting lifecycle: flight/accommodation search, personalized itineraries, entry requirements, booking creation and monitoring, upsell recommendations, and cancellation policy lookups with refund calculation.

Why this is not a trivial server

It exposes 10 tools backed by 6 distinct data collections (flights, accommodations, entry requirements, cancellation policies, activities, upsell offers) plus a mutable bookings collection, and combines several of them in a single call (e.g. build_trip_itinerary merges live weather + activities + accommodation pricing; cancel_booking merges a policy lookup with a booking write and computes a refund).

Data source

All catalog data (flights, accommodations, entry requirements, cancellation policies, activities, upsell offers) is fictional, seeded from seeds/*.json into MongoDB via seed_db.py. This keeps demos reliable and independent of third-party sandbox availability. Real-time weather still comes from Open-Meteo (no API key required).

If MongoDB is unreachable, every read tool falls back to small in-memory mock data so the server stays demoable even without a database connection. Write tools (create_booking, simulate_booking_alert, cancel_booking) require MongoDB and return a clear error otherwise.

Requirements

• Python 3.11+

• MongoDB running locally or remotely (e.g. docker run -p 27017:27017 mongo)

• pip install -r requirements.txt

Setup

# 1. Start MongoDB (example with Docker)
docker run -d --name travel-mongo -p 27017:27017 mongo

# 2. Seed the catalog collections
cd servers/travel_tools_server
python seed_db.py

# 3. Run the server standalone (for testing with Claude Desktop, etc.)
python server.py

Re-run python seed_db.py any time you want to reset the catalog to its original fictional data. It never touches bookings unless you pass --reset-bookings.

Collections

Tools

Read-only

• search_flights(origin, destination, date=None, max_price=None)

• search_accommodations(city, accommodation_type=None, max_price_per_night=None, min_guests=None)

• get_entry_requirements(destination_country, nationality="Guatemalteca")

• get_cancellation_policy(provider, product_type=None)

• get_upsell_recommendations(destination)

• build_trip_itinerary(destination, start_date, days, interests) — combines weather + activities + accommodations

Read/write (bookings)

• create_booking(client_name, product_type, reference_id, start_date, end_date, total_price_usd)

• get_booking_status(booking_id)

• simulate_booking_alert(booking_id, new_status, note) — simulates a GDS/monitoring alert (Case 4)

• cancel_booking(booking_id, provider, product_type, hours_before_departure) — reads the policy, computes the refund, writes the new status

Example call:

{
  "name": "cancel_booking",
  "arguments": {
    "booking_id": "BK-A1B2C3D4",
    "provider": "Avianca",
    "product_type": "flight",
    "hours_before_departure": 20
  }
}
