Files

• mcp_flight_client.py: Main client implementation for interacting with the MCP Flight Search service
• prompt_templates.py: Contains prompt templates for generating flight search queries

Installation

Install the required packages for this client:

pip install -r requirements.txt

Required packages:

• llama-index
• llama-index-llms-ollama
• llama-index-tools-mcp
• langchain-community

Installing Ollama

This client uses Ollama to run Llama 3.2 locally. To install Ollama:

1. Download Ollama from the official website
2. Install and start the Ollama application
3. Pull the Llama 3.2 model:

ollama pull llama3.2

Prerequisites

You need to have the MCP Flight Search service running.

Installing the MCP Flight Search Package

# Install from PyPI
pip install mcp-flight-search

Starting the MCP Server

You can start the MCP server using one of the following methods:

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

# Or using the Python module approach
python -m mcp_flight_search.server --connection_type http

Usage

python mcp_flight_client.py

This architecture shows how the MCP Llama3 Flight Search Client connects to the MCP Flight Search Server over HTTP. The client uses various libraries to interact with the server, which in turn uses the Model Context Protocol (MCP) to provide flight search functionality through tools like search_flights_tool.

The client leverages Ollama to run Llama 3.2 locally, providing powerful language model capabilities while maintaining privacy and reducing dependency on cloud services.
