Search for flights and retrieve detailed flight information using the Duffel API.
Find Flights MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Search for flights and retrieve detailed flight information using the Duffel API.
Think of it as having a travel agent in your chat who remembers everything you've discussed and can instantly search across dates and routes.
Once Find Flights is connected, these are the calls the assistant has available:
Building — The Building tool exposed by this server@smithery/cli on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
You will need one environment variable: DUFFEL_API_KEY_LIVE. 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.
Among the planning and project tracking 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. Find Flights's toolset — Building — is a fair guide to whether it matches your workflow. It is maintained by ravinahp; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
