# 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):

```bash
uvx geocode-mcp
```

Or install with pip:

```bash
pip install geocode-mcp
```

### MCP Configuration

Add to your MCP client configuration:

```json
{
  "mcpServers": {
    "geocoding": {
      "command": "uvx",
      "args": ["geocode-mcp"]
    }
  }
}
```

See the [`config/`](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:**
```json
{
  "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`](config/cursor-mcp.json) to your Cursor MCP settings.

### VS Code  
Copy the configuration from [`config/vscode-mcp.json`](config/vscode-mcp.json) to your VS Code MCP settings.

### Claude Desktop
Copy the configuration from [`config/claude-desktop.json`](config/claude-desktop.json) to your Claude Desktop config file.

See the [config README](config/README.md) for detailed setup instructions.

## Development

### Setup

```bash
# 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

```bash
# 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

```bash
# 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:

```bash
python -m geocode_mcp.server
```

Or use the development configuration in your MCP client:

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