MCP Flight Search

A flight search service built with Model Context Protocol (MCP). This service demonstrates how to implement MCP tools for flight search capabilities.

What is Model Context Protocol?

The Model Context Protocol (MCP) is a standard developed by Anthropic that enables AI models to use tools by defining a structured format for tool descriptions, calls, and responses. This project implements MCP tools that can be used by Claude and other MCP-compatible models.

Installation

# Install from PyPI
pip install mcp-flight-search

# Or install from the project directory (development mode)
pip install -e .

Usage

Start the MCP server:

# Using the command-line entry point
mcp-flight-search --connection_type http

# Or run directly
python main.py --connection_type http

You can also specify a custom port:

python main.py --connection_type http --port 5000

Environment Variables

Set the SerpAPI key as an environment variable:

export SERP_API_KEY="your-api-key-here"

Features

MCP-compliant tools for flight search functionality
Integration with SerpAPI Google Flights
Support for one-way and round-trip flights
Rich logging with structured output
Modular, maintainable code structure

MCP Tools

This package provides the following Model Context Protocol tools:

search_flights_tool: Search for flights between airports with parameters:
- origin: Departure airport code (e.g., ATL, JFK)
- destination: Arrival airport code (e.g., LAX, ORD)
- outbound_date: Departure date (YYYY-MM-DD)
- return_date: Optional return date for round trips (YYYY-MM-DD)
server_status: Check if the MCP server is running
