Geocode MCP Server
A Model Context Protocol (MCP) server that provides latitude/longitude coordinates for cities and locations using the OpenStreetMap Nominatim API.
Features
- 🌍 Global Geocoding: Get coordinates for any location worldwide
- 🆓 Free API: Uses OpenStreetMap Nominatim (no API key required)
- � MCP Integration: Works with Cursor, VS Code, Claude Desktop, and other MCP-compatible tools
- 📦 Easy Installation: Install via PyPI with
uvx geocode-mcp - �️ Modern Tooling: Built with Python 3.12+, async/await, and comprehensive testing
Quick Start
Installation
Install the package from PyPI using uvx (recommended):
uvx geocode-mcp
Or install with pip:
pip install geocode-mcp
MCP Configuration
Add to your MCP client configuration:
{
"mcpServers": {
"geocoding": {
"command": "uvx",
"args": ["geocode-mcp"]
}
}
}
See the config/ directory for specific examples for different tools.
Available Tools
mcp_geocoding_get_coordinates
Get latitude and longitude coordinates for a city or location.
Parameters:
location(required): City name, address, or location (e.g., "New York", "Paris, France", "123 Main St, Seattle")limit(optional): Maximum number of results to return (default: 1, max: 10)
Example Usage:
Get coordinates for Tokyo, Japan
Find the latitude and longitude of London, UK
What are the coordinates for New York City?
Get coordinates for "1600 Pennsylvania Avenue, Washington DC" with limit 5
