Global UK Government digger — a Claude Code plugin giving a direct line into UK government data and services. One MCP server, one command per sector, answers from live official APIs instead of stale training data.
Unofficial. Not affiliated with or endorsed by the UK Government. Output is official data, not legal, financial, or immigration advice.
/plugin marketplace add soheilfallah/ukdigger
/plugin install ukdigger@soheil-ukdigger

git clone https://github.com/soheilfallah/ukdigger
cd ukdigger
cp server/.env.example server/.env # fill in your keys (optional)
uv run --script server/test_server.py
The smoke test needs network access; keyed sections skip cleanly when no key is configured.
