OpenRegistry

Unmodified government company records, live. Cross-border ownership chain walker. 27 national registries.

Above: an AI agent walks the shareholders of Iceland Foods Ltd through 4 UK holding companies — WD FF MIDCO → ICELAND VLNCO → LANNIS → WD FF LIMITED — and surfaces the 8 individuals who actually own the chain (Tarsem Dhaliwal 41.35% as the largest shareholder, Walker family 51.31% combined). Every share count, every percentage, read verbatim from the registry's own CS01 PDFs.

OpenRegistry is your AI agent's live hotline to 27 national company registries — UK Companies House, France RNE, Germany Handelsregister, Italy InfoCamere (via EU BRIS), Spain BORME, Poland KRS, Korea OpenDART, Canada CBCA, 10 US states, and more.

We return the registry's own response — unmodified. Every field name, every status value, every raw filing byte (XHTML iXBRL / PDF / XBRL) is preserved exactly as the government's system emits it. The identifiers and jurisdiction routing let you reconstruct the government URL for any record. No aggregator markup. No field renames. No document re-rendering. No AI reinterpretation. No stale cache.

Chain queries across borders in a single prompt — a UK Ltd → its Luxembourg SARL → its Cayman LP → the Jersey trust → the individual beneficiary, all in one conversation. Walk ownership structures through 27 jurisdictions to unmask the real person behind any company.

The 6 pillars

1. Live	Every tool call is a real-time query to the upstream government registry API at the moment you ask.
2. Direct-to-government	No aggregator, no third-party data warehouse, no nightly scrape. Your AI talks to UK Companies House, France INSEE, German Registerportal, Korean FSS OpenDART directly.
3. Unmodified + source-linked	Every field name, every status code, every raw filing byte returned verbatim. The registry's own identifiers are preserved so any response traces back to the government record. Enterprise tier adds pre-synthesised source_url / registry_url / data_license fields.
4. Zero-stale	No cache layer we control can ever go stale. You see an update the moment the government records it. Contrast with commercial data providers that serve 6-24 hour-old snapshots.
5. Stable	Production-grade reliability, running on Cloudflare Workers' global edge + a warm pool of per-jurisdiction workers for stateful registries.
6. Cross-border	Chain queries across 27 registries in a single prompt. Walk UK Ltd → LU SARL → KY LP → individual without leaving the conversation.

Ready-to-use skills

We publish 10 professional Claude Agent Skills for the most common OpenRegistry workflows. Drop them into your Claude Code project's .claude/skills/ directory or into any Claude-compatible agent — invoke by intent.

#	Skill	Outcome in one prompt
1	KYC & Cross-Border Due Diligence	Full statutory dossier: profile + directors + UBO + shareholders + charges + latest accounts
2 ⭐	Cross-Border UBO Chain Walker	Walk the ownership chain across jurisdictions until you reach the real individual
3	Director Search & PEP Screening	Every company a person has run + co-director network
4	Live Company Accounts & XBRL Financials	Latest statutory accounts as machine-readable XBRL / iXBRL / PDF + key figures
5	Corporate Filing Monitor & Event Alert	Material filings in a window, categorised and flagged
6	Global Company Name Availability Check	Is a name free to register across 10+ countries?
7	Industry & Competitor Company Search	Every company in a sector across N jurisdictions, ranked + enriched
8	Shell Company Detector	Flag 1-director + no-accounts + overseas-office shells (AML signal)
9	Phoenix Company Radar	Detect dissolved-then-reborn fraud patterns (same director, same address)
10	Sector Gatekeeper List	Every CIMA / FCA / BaFin / FSS-licensed regulated entity

See skills/README.md for the skillpack overview.

Same 10 workflows, also as MCP prompts

Every skill above is also served by the MCP server as a named prompt — so any MCP-compatible client (Claude Desktop, Cursor, Cline, Goose, Zed, …) shows them in its prompt picker without installing skill files. Call prompts/list to discover them, prompts/get to invoke. Same names: kyc_cross_border_due_diligence, ubo_cross_border_chain_walker, director_search_pep_screening, live_company_accounts_xbrl, corporate_filing_monitor, global_company_name_availability, industry_competitor_search, shell_company_detector, phoenix_company_radar, sector_gatekeeper_list.

Anything else speaking MCP

Streamable HTTP transport per MCP spec 2025-06-18. OAuth 2.1 authorization flow for authenticated tiers (Dynamic Client Registration per RFC 7591 — no API key to paste).

AI agent frameworks (code samples)

Every major agent framework ships a generic MCP adapter, so OpenRegistry's 27 tools + 10 prompt workflows plug in with zero framework-specific code. Minimum working example per framework:

• LangChain / LangGraph (Python) → openregistry.sophymarine.com/docs/integrations/langchain
• LlamaIndex (Python) → /docs/integrations/llamaindex
• CrewAI (Python) → /docs/integrations/crewai
• Haystack (Python) → /docs/integrations/haystack
• AutoGen (Microsoft) (Python) → /docs/integrations/autogen
• Vercel AI SDK (TypeScript) → /docs/integrations/vercel-ai-sdk

Tiers

Tier	Price	Rate limit	Cross-border fan-out	Source URLs
Anonymous	free	20/min per IP	3 countries / 60s	identifiers only (URL reconstructable)
Free (signed in)	free	30/min per user	3 countries / 60s	identifiers only
Pro	$9/mo	180/min per user	10 countries / 60s	identifiers only
Max	$29/mo	900/min per user	30 countries / 60s	identifiers only
Enterprise	contact	3000/min per user	unlimited	source_url / registry_url / data_license synthesised

All tiers receive the full unmodified upstream data — the only thing Enterprise adds is pre-built source-URL fields for audit-trail convenience.

Provenance & Auditability

Every response preserves the upstream registry's identifiers so any fact can be verified at the government record:

• jurisdiction + company_id → reconstruct the government URL (e.g. https://find-and-update.company-information.service.gov.uk/company/09446231)
• document_id → the government's own filing identifier, resolvable back to their portal
• jurisdiction_data → the raw upstream object with every field name preserved
• Filing documents (XHTML iXBRL / PDF / XBRL) returned as raw bytes — no re-rendering

Enterprise tier pre-synthesises source_url / registry_url / registry_name / data_license / alternative_url into every response for one-click audit-trail in compliance reports.

Security and compliance

• Auth: OAuth 2.1 + PKCE, passwordless email magic links, RFC 7591 Dynamic Client Registration. No pre-shared API keys.
• Privacy: OpenRegistry proxies official public-registry data. Beneficial-ownership registers that became access-restricted post-CJEU C-37/20 (DE, ES, IT, NL, LU, AT, MT, PT) are not proxied — the tool returns 501 alternative_url pointing at the statutory gated portal (AML-obliged entities only). We explicitly flag where AML gates block the ownership chain.
• Rate limits: per-user for authenticated traffic, per-IP for anonymous — plus a per-jurisdiction upstream-protection cap shared across all users, to keep OpenRegistry a good citizen with the registries we depend on.
