A reliable Model Context Protocol (MCP) server for searching flights using the SerpAPI Google Flights engine. This server provides real-time flight search capabilities for both one-way and round-trip flights. Works well with claude ai. The flight search mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 6 defined tools rather than through you.
Everything the assistant can do here goes through one of these:
Prerequisites — The Prerequisites tool exposed by this serverInstallation — 1. Clone or download the server file: bash mkdir -p ~/tools/flightsearchConfiguration — The Configuration tool exposed by this serversearch_flights — The search_flights tool exposed by this serverserver_status — The server_status tool exposed by this serverLogging — The Logging tool exposed by this serverYou will need one environment variable: SERP_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
The server ships on PyPI as requests, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Flight Search's toolset — Prerequisites, Installation, Configuration and 3 more — is a fair guide to whether it matches your workflow. It is maintained by random-robbie; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Flight Search's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
