How it works
The technical decisions behind it.
Statutory data layer
Every figure — estate duty rates, executor fee caps, SBC income limits — encoded from official legislation. Source-cited. Updated after every Budget and MPC meeting.
Hybrid data strategy
Static statutory data maintained manually. Live APIs for exchange rates and public holidays with static fallback. Every response flags which source was used.
Tiered disclaimer architecture
Every result carries LOW, MEDIUM, or HIGH disclaimer based on consequence. Estate duty is HIGH — the executor files the REV267. Deadline references are LOW.
MCP + REST API
SSE transport for Claude Desktop direct connection. REST API for web integrations. One Railway deployment serving all clients simultaneously.
