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

io.github.MarvinSMX/mrvn-de-opendata-mcp MCP Server

This MCP server provides access to German public tenders, MaStR energy units, and EV charging stations. Data access is performed using your RapidAPI key, and the server is identified by the slug io-github-marvinsmx-mrvn-de-opendata-mcp.

🛠️ Key Features

Supplies data on German public tenders
Supplies data on MaStR energy units
Supplies data on EV charging stations
Uses a RapidAPI key for access

🚀 Use Cases

Retrieve German public tender information
Access MaStR-related energy unit data
Find EV charging station data in Germany

⚡ Developer Benefits

Centralizes multiple German datasets behind an MCP server
Requires only configuration of a RapidAPI key to enable access

⚠️ Limitations

Functionality depends on the availability of the referenced RapidAPI data sources

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 (12)

Tool	Purpose
`tender_search_notices`	Search procurement notices
`tender_get_notice`	Get one notice by ID
`tender_get_stats`	Aggregate tender stats
`tender_health`	Data freshness / health
`mastr_search_units`	Search MaStR energy units
`mastr_get_unit`	Get one unit by MaStR number
`mastr_get_stats`	Aggregate unit stats

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.
