MRVN DE Open Data MCP
Provides access to German open data through RapidAPI-hosted APIs (DE Tender Query, DE MaStR Units, DE Ladesäulen Query). Tool calls require a user's own RapidAPI key, which is forwarded to the RapidAPI gateway to authenticate procurement notice, MaStR energy unit, and EV charging station queries, stats, and health checks.

MRVN DE Open Data MCP
By MRVN.
Remote MCP server (Streamable HTTP, stateless) giving AI agents access to German open data:
Public procurement notices from oeffentlichevergabe.de – search by keyword, CPV code, Bundesland, value, deadline.
Energy units from the Marktstammdatenregister (MaStR) of the Bundesnetzagentur – solar, wind, storage etc., by location, technology, capacity.
EV charging stations from the Ladesäulenregister of the Bundesnetzagentur – by PLZ, Bundesland, power (kW), plug type, operator, radius or bounding box.
