mcp-monumenten by woonstadrotterdam - MCP Server

Monumenten MCP Server 🏛️

A Model Context Protocol (MCP) server that enables AI assistants to check monumental status of Dutch addresses. Connects to the Dutch BAG (Basisadministratie Adressen en Gebouwen) data and Ministry of Cultural Heritage (Rijksdienst voor het Cultureel Erfgoed) to identify national monuments, protected cityscapes, and municipal monuments.

[!NOTE] This MCP server is based on the monumenten package. For more information, see the monumenten package.

What This Does

🏠 Find verblijfsobject IDs - Convert Dutch addresses to BAG identifiers (verblijfsobject_id)
🏛️ Check monumental status - Determine if a property is protected as cultural heritage
📍 Support flexible address input - Search by postal code + house number or full address
🔍 Handle address variations - Support house letters and suffixes (30A, 30-2, etc.)

The AI can handle:

Postal code + house number format
House number suffixes (30-2, 30A, etc.)
Direct verblijfsobject ID lookups

Address Flexibility

The server handles Dutch address formats:

1234AB 30 - Basic postal code + house number
1234AB 30-2 - With house number suffix
1234AB 30A - With house letter
