Trip Tracker MCP Server

A Model Context Protocol (MCP) server that provides access to a trip tracking SQLite database. This server enables AI assistants to query and manage flight trip information including users, airports, and flight details.

Description

This MCP server exposes a SQLite database for the trip-tracker application through a set of tools and resources. It provides structured access to:

• Users: User account information and profiles
• Trips: Flight records including departure/arrival airports, times, airline info, flight numbers, reservations, terminals, and gates
• Airports: Airport data with IATA codes, names, cities, countries, and geographic coordinates

The server uses FastMCP and SQLAlchemy for async database operations, with input sanitization for security.

Installation

Ensure you have Python 3.11 or higher installed.

Install dependencies using uv:

uv sync

Or using pip:

pip install -r requirements.txt

Configuration

The server connects to a SQLite database.

You can override this location by setting the TRIP_TRACKER_DB environment variable:

export TRIP_TRACKER_DB=/path/to/your/database.db

Running the Server

Using Python directly

python main.py

Using uv

uv run main.py

The server will:

1. Initialize the database (create tables if they don't exist)
2. Start the HTTP server on http://127.0.0.1:9000

MCP Client Configuration

To use this server with an MCP client (like Claude Desktop), add it to your MCP settings:

{
  "mcpServers": {
    "trip-tracker": {
      "command": "uv",
      "args": [
        "--directory",
        "/home/user/trip-tracker-mcp",
        "run",
        "main.py"
      ],
      "env": {
        "TRIP_TRACKER_DB": "/path/to/your/database.db"
      }
    }
  }
}

Or using Python directly:

{
  "mcpServers": {
    "trip-tracker": {
      "command": "python",
      "args": ["/home/user/trip-tracker-mcp/main.py"],
      "env": {
        "TRIP_TRACKER_DB": "/path/to/your/database.db"
      }
    }
  }
}
