# MRVN DE Open Data MCP

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

- name: io.github.MarvinSMX/mrvn-de-opendata-mcp

- connection class: R1 (autonomous)
- trust: 97/100

**An agent can connect on its own if it already holds `X_RAPIDAPI_KEY`, `X_RAPIDAPI_KEY`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "mrvn-de-opendata-mcp": {
      "type": "http",
      "url": "https://de-opendata-mcp.pages.dev/mcp",
      "headers": {
        "X-RapidAPI-Key": "${X_RAPIDAPI_KEY}",
        "Authorization": "${X_RAPIDAPI_KEY}"
      }
    }
  }
}
```

Placeholders to fill: `${X_RAPIDAPI_KEY}`, `${X_RAPIDAPI_KEY}`.

## Quality 73/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: mastr_get_unit (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); mastr_health (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ladesaeulen_get_stats (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,442 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 4 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 12, about 1,442 tokens to load them all
- tool set hash: 61a89f1bcee6d7c4ed047d0cc6e463f9
- tools last changed: 2026-10-16T21:36:25.680Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.MarvinSMX/mrvn-de-opendata-mcp.svg)](https://protogrid.dev/servers/io.github.MarvinSMX/mrvn-de-opendata-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
