Summary
Live fares, one call.
It has a narrow job and does it: two airport codes and a date in, current Google Flights options out, which is what you want when the question is what a trip costs right now rather than what it usually costs.
What it is
An MCP server that searches Google Flights through SerpAPI. One search tool covers both directions of travel: two airport codes and a departure date return one-way options, and adding a return date makes it a round trip. Results carry price, timing and airline.
What you get
- Flight options between two airport codes for a departure date, with price, timing and airline on each
- Round trips from the same call, by supplying a return date
- Results from the live Google Flights engine rather than a cached fare table
Requirements
Python 3.7 or higher, the requests package, and a SerpAPI account - its key goes in the environment and every search spends SerpAPI credit. The server is a single file run directly, so give your client the full path to flight_search_server.py.
