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.
This server has a remotely hosted endpoint. Open its connector listing for connection details, authentication requirements, and setup instructions:
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.
Endpoint: https://de-opendata-mcp.pages.dev/mcp · Landing page: https://de-opendata-mcp.pages.dev/

tools/list works without a key. Tool calls require your own RapidAPI key, subscribed to
DE Tender Query, DE MaStR Units and/or
DE Ladesäulen Query. Each has a free BASIC plan (100 requests/day); paid plans exist for higher volume. Your key is forwarded only to the RapidAPI gateway and is not stored.

Source
worker.src.js is the Cloudflare Pages worker (JSON-RPC over POST /mcp, protocol versions 2025-06-18 / 2025-03-26 / 2024-11-05). build-tools.mjs injects tool definitions (tools.generated.json); smoke.mjs runs a smoke test against a URL.
