Overview

AI-generated overview

Lets an assistant search live airfare for flexible dates and broad destinations, comparing prices and booking links.

What you can do
Exposes one tool, search_flights, for searching live public airfare. It accepts vague or broad location names and flexible dates, resolves locations and dates, then returns up to 10 itineraries in an interactive comparison showing prices, schedules, stops and booking links.
When to use it
Useful when someone wants to compare airfares, has flexible dates, or gives only a vague destination. Suited to early trip or business-travel planning before booking.
Requirements
Network access to the remote endpoint at No local package, environment variables or headers are declared.
Before you install
Search queries with locations and dates are sent to a third-party service. Returned booking links lead to external sites where actual booking and payment happen, outside this server.

Installation

In SourceWeft

  1. Open Flightcat in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.flightcat%2Fflightcat/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
