Irish Tax Hub MCP Connector
Connect Claude directly to Irish tax tools and reference material. Irish Tax Hub exposes its tax calculators, current tax constants and key dates, together with Revenue's Tax & Duty Manuals and Ireland's double-taxation treaties (reused under Revenue's PSI Licence), as Model Context Protocol (MCP) tools, so answers are grounded in live data for the current tax year rather than the model's training. All tools are read-only.

Data and privacy
- The connector is stateless. It creates no account, builds no profile, and does not store your inputs or results.
- Tool inputs are sent to the Irish Tax Hub API in Ireland (EU-West-1) to compute a result and returned to you. All traffic is over HTTPS/TLS.
- All tools are read-only. Please do not send more personal data than a calculation requires.
