UK Rules & Rates

UK Rules & Rates (MCP server)

Sourced, date-aware UK tax, payroll and bookkeeping rates and deadlines for AI agents. Every answer comes with the date it applies from (and to), when it was last checked, and the official GOV.UK (or legislation.gov.uk) page it came from. There is also a UK business check built on Companies House data.

This repository only describes the hosted service. The service itself is run by Blake's Tec Solutions & Co and is not open source.
