Cq Zones MCP

cq-zones-mcp

Source: CQ's [WAZ Zone Definitions](https://cqww.com/cq_waz_list.htm) ("Updated and correct as of April 1, 2018"), © CQ Communications, Inc. and the World Wide Radio Operators Foundation (WWROF). The 40 CQ zones are CQ's: this package serves facts from CQ's list, each citing the zone it comes from, and links to CQ's page rather than copying it. Our GPL-3.0 licence covers our code, not CQ's data.

Checked against: AD1C's country files (Jim Reisert, AD1C), ADIF 3.1.7's subdivision zones, and ARRL's DXCC list. The tests fetch AD1C's and ARRL's files from their sites to validate the facts; neither is included here. where they differ, the owner's list wins (see docs/TRANSCRIPTION.md).

MCP server for CQ zones as CQ publishes them: the 40 zones of CQ's WAZ Zone Definitions (2018-04-01), the zones used by CQ's Worked All Zones award and the CQ World Wide DX Contest. Each zone's entities and subdivisions are given in ADIF's own DXCC and subdivision codes, with CQ's own wording where it splits an area.

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/cq-zones-mcp.git

cd cq-zones-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).
