🗺️ Geospatial & Cadastral MCP Server

Unified access to Dutch geospatial, cadastral, and topographical data

Access comprehensive Dutch geospatial data from PDOK (Publieke Dienstverlening Op de Kaart) and Kadaster through Claude Desktop. Query addresses, building heights, cadastral parcels, noise data, and administrative boundaries.

🌍 Available Data Sources (8 APIs)

📍 All coordinates returned in both RD (EPSG:28992) and WGS84 (EPSG:4326) formats

🚀 Quick Start

Prerequisites

• Python 3.9+
• No API key required (uses public PDOK services)

1️⃣ Installation

# Clone the repository
git clone https://github.com/TCLUBNL/geospatial-cadastral-mcp-server.git
cd geospatial-cadastral-mcp-server

# Create virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

2️⃣ Test the Server

python3 -c "from server.tools.search_location import search_location; r = search_location('Damrak 1, Amsterdam'); print(f'✅ Found: {r["results"][0]["display_name"]}')"

Expected output: ✅ Found: Damrak 1, 1012JS Amsterdam

🔌 Claude Desktop Integration

Step 1: Find Your Config File

macOS:

nano ~/Library/Application\ Support/Claude/claude_desktop_config.json

Windows:

notepad %APPDATA%\Claude\claude_desktop_config.json

Step 2: Add Server Configuration

Replace /absolute/path/to/ with your actual paths:

{
  "mcpServers": {
    "geospatial-cadastral": {
      "command": "/absolute/path/to/venv/bin/python",
      "args": ["/absolute/path/to/geospatial-cadastral-mcp-server/mcp_server_simple.py"],
      "env": {
        "PYTHONPATH": "/absolute/path/to/geospatial-cadastral-mcp-server"
      }
    }
  }
}

💡 Tip: Use pwd in your terminal to get the absolute path.

Step 3: Restart Claude Desktop

Quit Claude Desktop completely and reopen it. You should see the 🔌 icon indicating MCP servers are connected.

Step 4: Test in Claude

Try these example queries:

• "Find the address Damrak 1 in Amsterdam"
• "What's the height of the building at this address?"
• "Show me cadastral parcel boundaries for this location"
• "Convert RD coordinates 121000, 487000 to WGS84"
• "Get noise data near Schiphol airport"
