UK Company Data MCP server

Remote Model Context Protocol server with data on every UK company from Companies House: the register of 5.6 million companies plus balance sheet and profit and loss figures from about 35 million machine-readable (iXBRL) accounts filed since 2008, updated daily.

Ask Claude, ChatGPT, Cursor or any MCP client things like "check TESCO PLC", "compare these two suppliers", "find London software companies with falling cash" or "alert me if this customer files late".
