README
Registrum MCP Server
No Companies House API key needed. One Registrum API key gives your AI agent enriched, cached UK company data — structured financials, director networks, and company profiles — directly inside Claude, Cursor, and any MCP-compatible client.
Unlike raw Companies House API wrappers that require you to register at the CH developer portal and manage your own rate limits, Registrum handles all of that for you: iXBRL filings parsed into clean JSON, 24h/7d caching, and circuit-breaker resilience on CH outages.
5 tools, zero boilerplate. Search companies, pull structured financials, list directors, and map corporate networks.
