Company Check

Is this company real, healthy, and who controls it?

Requires the UK Due Diligence MCP server

A Claude skill that runs a full due diligence check on any UK company or director using official government registers. Wraps the UK Due Diligence MCP in a deterministic gather → enrich → score → report pipeline, with a swappable risk profile (lender, journalist, acquirer, AML, or your own) so the same check produces the right answer for the right audience.

The problem

You are about to do business with a company and you need to know if it is real, active, and well run. That means checking Companies House for status and directors, the Disqualified Directors register, the Gazette for insolvency notices, and HMRC for VAT validity. Four separate systems, and most people skip three of them.

What it does

Features

  • Company profile, officers, and PSC chain from Companies House
  • Filing compliance: accounts and confirmation statements overdue checks
  • Director disqualification search across every active officer
  • Gazette insolvency notices: winding-up, administration, CVL, strike-off
  • HMRC VAT validation and Charity Commission cross-reference
  • HM Land Registry corporate asset check (when relevant)
  • Five swappable risk profiles (lender, journalist, acquirer, AML, defaults) — or write your own
  • Weighted CLEAR / WATCH / FLAG verdict, traceable to the underlying register data
  • Deterministic pipeline: three Python scripts turn raw register data into a structured markdown report
