[![markatdataandbeyond/open-data-mcp MCP server](https://glama.ai/mcp/servers/markatdataandbeyond/open-data-mcp/badges/score.svg)](https://glama.ai/mcp/servers/markatdataandbeyond/open-data-mcp)

Ten tools I built to get facts from official open data, not guesses. This repository is an **open-source MCP server** (stdio). Each tool calls the official source API directly from your machine — no Apify token required for the local server.

Optional env keys (never commit them):

- `OPENALEX_API_KEY` — enables OpenAlex in scholar-search (free key from openalex.org)
- `NCBI_API_KEY` — higher PubMed rate limits (free from NCBI)

## Tools

| Tool | Official source |
|---|---|
| `dataandbeyond--eu-company-verify` | EU VIES + GLEIF |
| `dataandbeyond--dk-statistics` | Statistics Denmark (Statbank) |
| `dataandbeyond--scholar-search` | Crossref, arXiv (+ OpenAlex with key) |
| `dataandbeyond--pubmed-search` | NCBI PubMed E-utilities |
| `dataandbeyond--eu-tenders` | TED API v3 |
| `dataandbeyond--france-company-search` | Recherche d'entreprises (INSEE/DINUM) |
| `dataandbeyond--nordic-company-registry` | Brønnøysund + PRH/YTJ |
| `dataandbeyond--clinical-trials` | ClinicalTrials.gov API v2 |
| `dataandbeyond--vin-decoder-recalls` | NHTSA vPIC + Recalls |
| `dataandbeyond--weather-forecast` | MET Norway (+ Nominatim geocode) |

## Run locally

```bash
npm ci
node src/index.js
```

Point your MCP client at the stdio command `node /path/to/open-data-mcp/src/index.js` (or the Docker image built from the Dockerfile in this repo). `tools/list` works with no environment variables.

Docker:

```bash
docker build -t open-data-mcp .
docker run --rm -i open-data-mcp
```

## Hosted version

The same ten tools are also available as **pay-per-event Apify Actors** if you want a hosted endpoint instead of running the server yourself:

## Demo

Short terminal recordings of three Actors — direct Apify API and via this repo's MCP stdio proxy. Token values are never printed (`$APIFY_TOKEN` only).
