MRVN: German public tenders, MaStR energy units and EV charging stations via your RapidAPI key.

VerifiedStreamable HTTPWeb executableLocation & LifestyleData & Analytics

Overview

AI-generated overview

Remote MCP server for German open data: search public procurement notices, MaStR energy units and EV charging stations, with aggregate statistics.

What you can do
Search, filter and retrieve German public procurement notices by keyword, CPV code, Bundesland, buyer, value or deadline, plus aggregate tender statistics and data-freshness checks.
When to use it
Useful when you need German public-sector tender information, registered energy installations (solar, wind, storage) or EV charging station data, and want an assistant to search, look up single records and summarize counts without building your own API integration.
Requirements
A remote Streamable HTTP endpoint; no local runtime or package. A RapidAPI key sent in the X-RapidAPI-Key header (or as a Bearer token), subscribed to the relevant DE Tender Query, DE MaStR Units and/or DE Ladesäulen Query APIs. Network access to the endpoint and the RapidAPI gateway.
Before you install
The RapidAPI key is a secret and is forwarded to the RapidAPI gateway; the server states it is not stored. Free BASIC plans are limited to 100 requests per day per API, and paid plans exist for higher volume. The server keeps an anonymous per-tool daily call counter. Data comes from third-party public registers and may lag behind the source.

Installation

In SourceWeft

  1. Open MRVN DE Open Data MCP in the dashboard and add it to a workspace.
  2. Connect X-RapidAPI-Key credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.MarvinSMX%2Fmrvn-de-opendata-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

MRVN DE Open Data MCP

[MRVN DE Open Data]

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.

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.
