> **Source: the Deutscher Amateur-Radio-Club e.V. (DARC):** the [DOK-Liste](https://www.darc.de/fileadmin/filemounts/referate/dx/DOK-Liste.pdf) (DARC DX-Referat, by Karsten Radwan, DL2ABM, 26.12.2016) and the [special-DOK list](https://www.darc.de/fileadmin/filemounts/referate/sdok/SDOK_List.csv) (DARC SDOK-Referat). DOKs are DARC's: this package serves the lists' rows as facts, each citing its page or row, and links to DARC's files rather than copying them. Our GPL-3.0 licence covers our code, not DARC's data.

MCP server for **DARC DOKs and special DOKs** as DARC publishes them: the local-club codes of DARC's [DOK-Liste](https://www.darc.de/fileadmin/filemounts/referate/dx/DOK-Liste.pdf) (2016-12-26) and the event codes of DARC's [special-DOK list](https://www.darc.de/fileadmin/filemounts/referate/sdok/SDOK_List.csv), with each special DOK's validity window. DOKs are used for DARC's DLD award, the DOK best-lists and the WAG contest, and in ADIF's `DARC_DOK` field.

Part of the [qso-graph](https://qso-graph.io/) project. **No network, no authentication**: the facts from the owner's list ship with the package, and every answer names its source.

}
```

#### Cursor

Add to `.cursor/mcp.json` (project-level) or `~/.cursor/mcp.json` (global):

## MCP Inspector

```bash
darc-dok-mcp --transport streamable-http --port 8018
```

Then open the MCP Inspector at `http://localhost:8018`.

## Development

```bash
git clone https://github.com/qso-graph/darc-dok-mcp.git
cd darc-dok-mcp
uv sync --group dev
uv run pytest
```

`scripts/fetch_published.py` fetches the owner's document(s) into `published/` (not committed) and checks their SHA-256s; `uv run pytest --live` runs the tests that need them. `scripts/build.py` regenerates `derived/` and `load.sql`, a PostgreSQL load for QSO Graph's reference data (load QG ADIF's `adif` schema first).

## License

darc-dok-mcp's own code is GPL-3.0-or-later. See [LICENSE](LICENSE). The data it serves is the owner's, credited at the top of this page: our licence doesn't cover it, and we claim no rights in it. The owner's document itself is not included; `data/SOURCE.json` records its URL and SHA-256 so anyone can check the facts against it. Files we built from the facts (`data/derived/`) are ours and labelled as ours. How the owner's text was read is recorded in [docs/TRANSCRIPTION.md](docs/TRANSCRIPTION.md). See [NOTICE](NOTICE).
