CheapFlights — Claude Code Plugin

Find cheap flights through natural conversation. Search, compare dates, and track price drops — no account or API key required.

What it does

Ask Claude naturally:

"Check flights from Montreal to New York on April 30" "Compare Friday vs Saturday for JFK to London" "Track this price and tell me if it drops"

Claude returns direct links to Google Flights, Kayak, Skyscanner, and Momondo — pre-filled with your exact route and date. One click to see real prices.

Requirements

• Claude Code
• Python 3.10 or later

Installation

In Claude Code, run:

/plugin install github:chitraju-chaithanya/cheap-flights-mcp

Restart Claude Code. Done.

Getting real prices (optional)

By default the plugin returns deep links to flight search engines. To get actual prices directly in Claude, add a free Amadeus API key:

1. Sign up at developers.amadeus.com — no credit card required
2. Create a self-service app and copy your API key and secret
3. Add to ~/.claude/settings.json:

{
  "mcpServers": {
    "cheap-flights": {
      "command": "cheap-flights-mcp",
      "env": {
        "AMADEUS_API_KEY": "your_key_here",
        "AMADEUS_API_SECRET": "your_secret_here"
      }
    }
  }
}

Free tier: 2,000 API calls per month.
