Companies House

Overview

Companies House is a Model Context Protocol server that connects AI assistants to the UK Companies House public register. Search companies, officers, ownership records, filings and documents directly through Claude, Cursor, VS Code and other MCP clients. The server exposes Companies House data as tools your AI assistant can invoke in real time.

Install locally with npx -y companies-house-mcp. You'll need a Companies House API key to authenticate. The server runs on your machine over stdio, currently at version v4.0.0 under the MIT license. Full source code is available at aicayzer/companies-house-mcp on GitHub, where the project has 13 stars.

Find Companies House in the AI & Agents category on mcp.site. It works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and compatible MCP clients. If you maintain this server, claim this listing to verify ownership and keep information up to date.
