Overview

AI-generated overview

A local MCP server that gives an assistant 12 tools to look up UK Companies House data: company search, profiles, officers, PSCs and filings.

What you can do: Search UK Companies House for companies and retrieve cleaned results across 12 tools covering search, company profiles, officers, persons with significant control (PSCs), filings and more.
When to use it: Useful when you need an assistant to research UK companies, check directors or ownership, or pull filing information during due diligence, compliance or business research.
Requirements: Runs as a local process installed from the PyPI package bartram-companies-house over stdio. An API key can be supplied via the COMPANIES_HOUSE_API_KEY environment variable; a default key is provided, but your own is recommended for heavy or production use. Desktop only.

Before you install

The server declares no authentication and ships a default API key for convenience; heavy or production use should set your own key in COMPANIES_HOUSE_API_KEY. Queries go to the UK Companies House service, so lookups are visible to that third party. The tools are described as read-only lookups, but verify before relying on results.

Installation

In SourceWeft

Open UK Companies House in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
