darc-dok-mcp

Source: the Deutscher Amateur-Radio-Club e.V. (DARC): the DOK-Liste (DARC DX-Referat, by Karsten Radwan, DL2ABM, 26.12.2016) and the special-DOK list (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 (2016-12-26) and the event codes of DARC's special-DOK list, 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 project. No network, no authentication: the facts from the owner's list ship with the package, and every answer names its source.

Development

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).
