Air quality MCP server for German cities (UBA)
Current German Environment Agency (UBA) air quality data for major German cities directly in Claude or ChatGPT, through InfraNode's free, keyless MCP tool.
What the MCP tool does
The air_quality MCP tool returns readings from the nearest UBA station: PM10 and PM2.5, NO2, O3 and SO2. The AI agent calls it when you ask about a city's air quality.
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 air_quality tool
itself:
How is the air quality in Munich today?
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.
