RMV MCP Server

RMV MCP Server

A simple MCP (Model Context Protocol) server with two functions to call RMV APIs for information about nearby stations and departure boards.

Setup

1. Install dependencies and create a virtual environment:

This project uses uv, an extremely fast Python package installer and resolver which creates and manages virtual environments (like venv). If you don't have it, see the official uv documentation to install it.

    uv init

By using uv, there is no need to explicetily create a venv and install requirements. All information about the uv project is in the file pyproject.toml. Consequently, there is no requirements.txt in this repo.

1. Configure your RMV Access ID:

• Create a .env file in the project root.
• Add your RMV ACCESS_ID to it:

        ACCESS_ID="your-rmv-api-access-id"

• You can get an ACCESS_ID from the RMV open data platform.

Usage

1. Integrate the MCP server to Gemini CLI

Go and find the file .gemini/settings.json in your home directory. Add the following block:

    "mcpServers": {
      "rmvServer": {
      "command": "uv",
      "args": [
        "run",
        "--project",
        "/YOURPATH/rmv_mcp/",
        "/YOURPATH/rmv_mcp/rmv_server.py"
      ]
    }
  },

Gemini CLI

In Gemini CLI check with /mcp the new MCP server:
