SNCF MCP Server

A Model Context Protocol (MCP) server for accessing French railway (SNCF) transportation data with Claude AI.

Overview

This MCP server allows Claude to:

• Search for train journeys between French stations
• Get information about train stations including facilities
• Access real SNCF data through their API

Quick Start

The quickest way to use this server is with npx:

npx sncf-mcp-server --api-key=YOUR_SNCF_API_KEY

You need to register for an SNCF API key at SNCF Open Data.

2. Create or edit the claude_desktop_config.json file:

   {
     "mcpServers": {
       "sncf": {
         "command": "npx",
         "args": [
           "-y", 
           "sncf-mcp-server", 
           "--api-key=YOUR_SNCF_API_KEY"
         ]
       }
     }
   }
