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][tender], [DE MaStR Units][mastr] and/or [DE Ladesäulen Query][ladesaeulen]. 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.

OpenAPI specs (REST via RapidAPI)

The three backing REST APIs are described in openapi/ (OpenAPI 3.0.3, server = RapidAPI gateway, header X-RapidAPI-Key):

  • openapi/de-tender-query.openapi.yaml: German public procurement notices
  • openapi/de-mastr-units.openapi.yaml: MaStR energy units
  • openapi/de-ladesaulen-query.openapi.yaml: EV charging stations (Ladesäulenregister)

Privacy

The server keeps an anonymous per-tool call counter: one count per tools/call per tool name per UTC day (Workers KV). No IPs, API keys, user agents or arguments are stored. Your RapidAPI key is only forwarded to the RapidAPI gateway.
