get_officers(company_number, items_per_page?, start_index?, register_type?)

BYO key. Pass ?_apiKey=<key> on the gateway URL. Register a free key at https://developer.company-information.service.gov.uk.

https://api.company-information.service.gov.uk — HTTP Basic auth (key as username, empty password).

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "companies-house": {
      "url": "https://gateway.pipeworx.io/companies-house/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Companies House data" })

The gateway picks the right tool and fills the arguments automatically.
