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

  • πŸ†“ Free API: Uses OpenStreetMap Nominatim (no API key required)

  • οΏ½ MCP Integration: Works with Cursor, VS Code, Claude Desktop, and other MCP-compatible tools

  • πŸ“¦ 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

Response Format:

{ "query": "Tokyo, Japan", "results_count": 1, "coordinates": [ { "latitude": 35.6762, "longitude": 139.6503, "display_name": "Tokyo, Japan", "place_id": "282885117", "type": "city", "class": "place", "importance": 0.9, "bounding_box": { "south": 35.619, "north": 35.739, "west": 139.619, "east": 139.682 } } ] }

Integration Guides

Cursor

Copy the configuration from config/cursor-mcp.json to your Cursor MCP settings.

VS Code

Copy the configuration from config/vscode-mcp.json to your VS Code MCP settings.

Claude Desktop

Copy the configuration from config/claude-desktop.json to your Claude Desktop config file.

See the config README for detailed setup instructions.

Development

Setup

# Clone the repository git clone https://github.com/X-McKay/geocode-mcp.git cd geocode-mcp # Install with development dependencies pip install -e ".[dev]"

Running Tests

# Run all tests pytest # Run with coverage pytest --cov=src/geocode_mcp --cov-report=html # Run specific test files pytest tests/test_geocoding.py -v pytest tests/test_mcp_server.py -v

Code Quality

# Format code ruff format # Lint code ruff check # Run all checks ruff check && ruff format --check

Local Development

For local development and testing, you can run the server directly:

python -m geocode_mcp.server

Or use the development configuration in your MCP client:

{ "mcpServers": { "geocoding": { "command": "python", "args": ["-m", "geocode_mcp.server"], "cwd": "/path/to/geocode-mcp", "env": { "PYTHONPATH": "/path/to/geocode-mcp/src" } } } }
