Infranode: keyless, Open Source MCP Server for AI agents .
Hi all, I built InfraNode, an open-source (Apache-2.0) MCP server that gives AI assistants live open data for 84 German cities: weather, air quality, public transit departures, parking, bike counts, solar potential and more, all from official open-data sources.
Why it might interest this community:
- Keyless and hosted. Point your client at the remote server (mcp.infranode.dev, streamable-http) and the tools just work. No signup, no API key.
- Around 48 read-only tools, plus a get_city_overview discovery tool so an agent can see in one call which data a given city offers and which tool to use next.
- The same data is also a plain REST API, so it works outside MCP too.

Full disclosure: I am the author. I would love feedback on the tool design and especially the discovery flow.
