An unofficial CLI and MCP server for the [UK Companies House API](https://developer.company-information.service.gov.uk/). Look up any UK company
An unofficial CLI and MCP server for the UK Companies House API. Look up any UK company, check its officers, trace ownership, dig into filings, run a due diligence scan — from your. That is what the companies house mcp mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
The server publishes 6 tools. What each one is for:
get_appointments — every company a given officer has ever been appointed toget_filing_document — retrieve an individual filing documentget_company_registers — statutory registers (members, directors, secretaries, charges)get_exemptions — disclosure exemptionsget_uk_establishments — UK establishments of overseas companiesget_officer_disqualifications — disqualification orders made against an officercompanies-house-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Companies House MCP's toolset — get_appointments, get_filing_document, get_company_registers and 3 more — is a fair guide to whether it matches your workflow. It is maintained by aicayzer; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
