MCP InfraNode is also available as an MCP server for AI assistants like Claude and ChatGPT.

Solar cadastre MCP server for German cities

Roof-based PV potential from the solar cadastres of the federal states directly in your AI assistant, through the free, key-free MCP tool by InfraNode. No API key, no installation.

What the MCP tool does

With resource='solar-roofs' the tool returns the suitability of roof areas in the city for photovoltaics. Unlike the pure irradiation value, the cadastre accounts for the actual roofscape.

Use it in Claude or ChatGPT

Connect the InfraNode MCP server to your AI client once (see set up the MCP server). After that a natural-language question is enough, the assistant calls the get_city_resource tool itself:

How large is the rooftop PV potential in Bochum?

The MCP server is free, keyless and remote over Streamable HTTP at https://mcp.infranode.dev/mcp. No API key, no install.

Prefer the REST API?

The same data is also available without an AI agent as a classic REST API, also free and keyless.

Frequently asked questions

Why is not every city included?
The solar cadastre is maintained per federal state and is not openly available everywhere. For cities not covered the tool honestly reports that no data is available.
How does it differ from the solar tool?
The solar tool provides irradiation at the location, the cadastre the suitability of concrete roof areas. The two complement each other.
