README
# dk-eli-mcp
<!-- mcp-name: io.github.matematicsolutions/dk-eli-mcp -->
An MCP server for the Danish **Retsinformation** legal database (`retsinformation.dk`). It
fetches Danish legislation as LexDania 2.1 XML behind native ELI URIs, with verifiable
citations.
Part of the MateMatic `eu-legal-mcp` production line - after PL, DE, AT, ES, FI, IE, NL, SE, FR
and LU. Same citation contract, Retsinformation source. Denmark is ELI-native: every document
has a stable `data.europa.eu/eli`-typed identifier exposed as a `retsinformation.dk/eli/...` URL.
> **Scope.** This MVP grounds Danish documents by ELI coordinate (`year` + `number` in the `lta`
> collection = Lovtidende A) or by accession number, and lists documents changed on a date. The
> API is path-based, not keyword search. It covers laws (LOV), consolidated laws (LBK), executive
> orders (BEK), circulars (CIR) and guidelines (VEJ). Language: Danish. Every response carries a
> `dataset_note`.
>
> **Licence of the data.** Danish legislation in Retsinformation is official public information
> published as Open Data (keyless). This connector relays it with attribution and a `source_url`.
## The tools
| Tool | What it does |
|---|---|
| `dk_get_act` | Metadata for a document by year + number, or by accession. |
| `dk_get_text` | Full LexDania XML of a document (verbatim official text). |
| `dk_recent_changes` | Documents changed on a given date (harvest API). |
| `dk_coverage` | Declare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback. |
Every response carries the contract: `eli_uri` (a full ELI URL, e.g.
`https://www.retsinformation.dk/eli/lta/2018/502`), `human_readable_citation`
(e.g. `Databeskyttelsesloven (LOV nr. 502 af 23/05/2018)`), and `source_url`.
## Install
Run it with no install step (once published to PyPI):
```bash
uvx dk-eli-mcp
```
Or from source:
```bash
cd dk-eli-mcp
pip install -e .
```
## Configure (Claude Code / any MCP client)
```json
{
"mcpServers": {
"dk-eli-mcp": { "command": "dk-eli-mcp" }
}
}
```
### Windows 11 with Smart App Control
Smart App Control blocks unsigned executables, which covers `uvx.exe`, `pip.exe`
and the `dk-eli-mcp.exe` launcher that pip writes at install time. The `python.exe` and
`py.exe` from the python.org installer are signed by the Python Software
Foundation, so running the module through the interpreter works:
```bash
python -m pip install dk-eli-mcp
python -m dk_eli_mcp
```
`pip.exe` is blocked for the same reason, so install with `python -m pip`, not
`pip install`. If `python` is not on PATH, use the Windows launcher: `py -3 -m dk_eli_mcp`.
```json
{ "mcpServers": { "dk-eli-mcp": { "command": "python", "args": ["-m", "dk_eli_mcp"] } } }
```
Do not turn Smart App Control off to work around this - it cannot be re-enabled
without reinstalling Windows.
Environment:
- `DK_ELI_BASE_URL` - default `https://www.retsinformation.dk`
- `DK_ELI_API_URL` - default `https://api.retsinformation.dk` (harvest API)
- `DK_ELI_CACHE_DIR` - default `~/.matematic/cache/dk-eli`
- `DK_ELI_AUDIT_DIR` - default `~/.matematic/audit`
No API key. Retsinformation open data is keyless.
> The harvest API behind `dk_recent_changes` is only available 03:00-23:45 Danish time. Outside
> that window the tool returns an `upstream_error`; an empty list during the window means nothing
> changed on that date.
## Governance
- **Public data only** - read-only against Retsinformation; no client data leaves the machine.
- **Audit log** - every tool call appends one JSON line to `~/.matematic/audit/dk-eli-mcp.jsonl`.
- **Vendor-neutral** - talks only to `retsinformation.dk`; no LLM provider, no telemetry.
- **Verifiable citations** - every response is independently checkable via `source_url`.
See `CONSTITUTION.md` and `DISCOVERY.md`.
## Tests
```bash
pip install -e ".[dev]"
pytest tests/test_instructions_drift.py tests/test_parse.py -v # offline
pytest tests/test_smoke.py -v # hits live Retsinformation
```
