OPEN REGISTRY
An MCP server with 27 tools that connects AI clients to the official registries of 26 countries. Each call returns whatever the registry sent.
You can also search a company directly on the web, without signing up. Or point any AI client at the MCP endpoint below.
Free, no signup. 24 registries on the web, 26 via MCP.
Paste the config below into any MCP 2025-06-18 client - Claude Desktop, Cursor, Cline, Claude Code, anywhere. On the first tool call, the client opens your browser for a one-time passwordless sign-in.

marketing site.

Describe the question in plain language - the AI chains the right tools across the right jurisdictions.
One AI prompt. Five tool calls. The whole legal shareholding tree of Iceland Foods Limited surfaces - up through four UK holding layers to the eight named individuals who actually own the supermarket. Every byte comes back live from Companies House. No aggregator, no cache, no API key.

Five recursive calls, four layers, ~30 seconds. Every assertion above is backed by a
Companies House URL the auditor can verify independently. On the enterprise tier
jurisdiction_data.source_url in each response carries the direct link to
find-and-update.company-information.service.gov.uk; on free / pro / max tiers
the registry-issued identifier is enough to reconstruct the URL.
Same five-call loop generalises to cross-border due diligence: swap
jurisdiction: "GB" for any of the
26 covered registries at any
recursion. Productised KYB / UBO flow at /solutions/kyb.
Free anonymous tier works without any signup - just paste the MCP URL. Sign in for a higher quota; upgrade for serious multi-country fan-out. Enterprise (custom) adds full upstream provenance in every response.

Inclusions, citations and live integrations across the MCP, AI agent and developer-tools ecosystem. Every link below is a public, third-party listing - not a vendor logo wall.
OpenRegistry exists because government registries publish their data, MCP defines a portable transport, and a long line of open-source projects do the heavy lifting upstream of every tool call.
