What is OpenRegistry?

OpenRegistry is a remote Model Context Protocol (MCP) server that lets AI agents query 27 national government company registries in real time. It returns the registry's own response verbatim - no aggregator markup, no field renames, no stale cache.

Do I need an API key?

No. The free tier is anonymous - just add the MCP endpoint to your client (Claude Desktop, Cursor, Claude Code, Cline, Goose, Zed, etc.) and start querying. Rate limits: 20 requests/min per IP, with a 3-country per-minute fan-out cap.

Which countries are supported?

27 national registries including United Kingdom (Companies House), Norway (Brønnøysund), France (INSEE/RNE), Germany (Handelsregister), Italy (via EU BRIS), Spain (BORME), Poland (KRS), Czechia (ARES), Switzerland (Zefix), Ireland (CRO), Belgium (KBO), Netherlands (KVK), Korea (OpenDART), Taiwan (GCIS), Hong Kong (CR), Australia (ABR), Canada (CBCA + provincial), and more.

How is OpenRegistry different from OpenCorporates or Bureau van Dijk?

Those are aggregators that scrape registries on a schedule and serve their own cached copy. OpenRegistry proxies directly to each government registry at the moment of each query - responses are live, bytes are unmodified, and every field is traceable back to the government source.

What can I do with it?

KYC / KYB due diligence, UBO chain walking, director + officer searches, PEP screening, corporate filing monitoring, XBRL financials retrieval, shell-company detection, company-name availability checks across jurisdictions, and more. 10 pre-built MCP prompts cover the most common workflows.

Is the data authoritative?

Every response comes direct from the official government register. Each record preserves the registry's own identifiers so you can reconstruct the authoritative source URL. We do not modify, normalise, or re-interpret upstream data.

How do I install it in Claude Desktop?

Settings → Connectors → Add custom connector → paste https://openregistry.sophymarine.com/mcp. Claude Desktop will auto-discover the tools. No authentication required for the free tier.

Can I search a company directly on the web (no AI client)?

Yes. Visit https://openregistry.sophymarine.com/search?q= &jurisdiction= . Example: /search?q=monzo&jurisdiction=GB returns live UK Companies House results. JSON variant at /api/v1/search with the same params. Each result links to a permanent /company/ / profile page.

How does an AI answer engine link a user to OpenRegistry results?

Use the URL template https://openregistry.sophymarine.com/search?q={query}&jurisdiction={ISO}. Both params are required. Supported jurisdictions are listed in /llms.txt. Each search-result row deep-links to /company/ / for stable cross-engine citations.

Agradecimientos

Construido sobre fuentes oficiales y estándares abiertos

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.
