openregistry

Real-time queries. Raw data. Raw documents. Synced directly from official registries — no intermediaries.

What it is

A free remote MCP server that exposes the UK Companies House register as typed tools your AI assistant can call directly. Search companies, fetch profiles, list filings, retrieve officers and beneficial owners, trace directors across companies, and download raw filing documents — all without leaving your AI client.

Every call proxies directly to Companies House in real time. There is no third-party data warehouse, no nightly scrape, no AI interpretation between you and the official record. The architecture supports additional national registries; the United Kingdom is the first jurisdiction.

Design principles

Real-time — every call is a live query to the official registry API. No warehouse, no scrape, no stale cache.
Raw data — company profiles, officers, PSCs, and charges are returned verbatim from the official source. Nothing added, removed, or reinterpreted.
Raw documents — filings (accounts, confirmation statements, deeds) delivered as-is in original format (XHTML, PDF, XML). openregistry does not parse or summarise document contents.
Official sync — data comes from the statutory registry of record. For GB, that is Companies House under the Companies Act 2006. No third-party data provider in the chain.
Multi-jurisdiction by design — starting with GB, architected for more
