Overview

openregistry

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

openregistry is a free remote MCP server — a platform by sophymarine — that connects AI agents directly to official national company registries as typed, structured tools. 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 the official registry in real time. There is no third-party data warehouse, no nightly scrape, no AI interpretation between you and the official record.

Hosted endpoint: https://openregistry.sophymarine.com/mcp

Why openregistry

Real-time. Every tool call is a live query to the upstream registry API — not a cached snapshot, not a third-party aggregator, not a nightly scrape. Pass fresh=true to bypass even the short-lived performance cache.
Raw data. Company profiles, officer lists, shareholder registers, beneficial-ownership entries, charges, and filing metadata come back with upstream field names preserved. No opinions. No AI interpretation between you and the record.
Official source. Data comes from the statutory registry of record for each jurisdiction — not a scraper third-hand.
No intermediaries. No third-party data warehouse, no nightly scrape, no translation layer between your AI and the registry.
Free for anonymous use. No API key, no account, no installation — add the server URL and it works. Sign in (passwordless, email magic link) for higher rate limits and multi-country search fan-out. See Tiers.

Anything else speaking MCP

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

Tiers

Tier	Price	Rate limit	Multi-country search fan-out
Anonymous	free	20/min per IP	3 countries / 60s
Free (signed in)	free	30/min per user	3 countries / 60s
Pro	$9/mo	180/min per user	10 countries / 60s
Max	$29/mo	900/min per user	30 countries / 60s
Enterprise	contact sales	3000/min per user	unlimited + source URLs included

All tiers receive the same unified schema and full raw upstream data. Enterprise adds synthesised source-URL / registry-name / data-license fields.

Examples

Look up a company and fetch its latest accounts:

"Search Companies House for Monzo Bank, get their full company profile, and show me their most recent accounts filing."

The assistant will chain search_companies → get_company_profile → list_filings(category='accounts') → fetch_document and analyse the filing inline.

Trace a director across every company they've run:

"Find every UK company where Elon Musk has been a director, and show me which ones are still active."

→ search_officers(GB) → get_officer_appointments(GB).

Beneficial ownership analysis:

"For company number 00000006 (Pilkington), who are the persons with significant control, and what mortgages are registered against them?"

→ get_persons_with_significant_control(GB) + get_charges(GB).

Figure out the country first:

"I think a company called 'Equinor' exists somewhere — find it for me."

openregistry pops an MCP elicitation dialog showing its country guesses (NO, GB, DK) — the user deselects / adds / confirms within tier cap, the server runs the final list in parallel and merges results with per-row jurisdiction tags. Multi-country search never runs silently behind the user's back.

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) are not proxied — the tool returns 501 alternative_url pointing at the statutory gated portal (AML-obliged entities only).
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.
