Sector Gatekeeper List

Sector Gatekeeper List

List every regulated / licensed entity in a sector, direct from the regulator's register.

Prerequisite: configure the OpenRegistry MCP server

This skill calls OpenRegistry MCP tools (search_companies, get_company_profile, list_filings, fetch_document, etc). Add the server to your AI client config before invoking:

{
  "mcpServers": {
    "openregistry": { "url": "https://openregistry.sophymarine.com/mcp" }
  }
}

Free anonymous tier, no API key required. Restart your client after adding. If the tool calls below return tool not found, the MCP server isn't wired up — see openregistry.sophymarine.com/docs.

What you get

• Live regulator register access where the jurisdiction exposes it freely — Cayman CIMA (all 35 authorization categories from Banking Class A/B to Virtual Asset Service Provider), UK Companies House + (limited) FCA Register, Korean DART (supervised issuers), Hong Kong SFC (via equivalent), Canadian CBCA (federal corps).
• Unmodified native records: licence reference, authorization type, status, effective dates — field names preserved as the regulator emits them.
• Native category filtering where the regulator supports type-filter search (CIMA uses type: prefix for any of its 35 categories).
• Cross-jurisdiction when needed: for a global "all licensed crypto brokers" view, chain queries across multiple regulators in parallel.

Example prompts

List every CIMA-authorised Mutual Fund in the Cayman Islands. 
Split by category (Licenced / Registered / Master / Administered / Limited Investor).

Show all Cayman Islands Virtual Asset Service Providers (VASPs) with a current licence.

For Korea, list the top 20 listed issuers on KOSPI by most recent annual-report filing date.

Workflow — CIMA (Cayman) example

Native type-filter search

search_companies({ 
  jurisdiction: "KY", 
  query: "type:Mutual Fund - Registered" 
})

CIMA's 35 authorization types (from list_jurisdictions({ jurisdiction: "KY" })):

• Banking: Class A, Class B
• Mutual Funds: Licenced, Registered, Master, Administered, Limited Investor
• Private Fund
• Mutual Fund Administrators: Full, Restricted
• Insurance: Class A/B/C/D Insurer, Insurance Agent, Broker, Manager
• Corporate Services: Company Manager, Corporate Service Provider
• Money Services
• Trusts: Trust, Trust (Controlled Subsidiary), Trust (Registered PTC), Trust (Restricted), Nominee (Trust)
• Building Societies / Credit Unions / Development Bank
• Portfolio Insurance Company
• Securities: Full, Restricted, Registered Person
• Virtual Asset Service Providers: Licence, Registration

Pass any of those as a type:<category> prefix.

Step 2 — Enrich each entity

For interesting candidates:

get_company_profile({ jurisdiction: "KY", company_id })

Returns the full CIMA record including authorization date, status, address.

Step 3 — Report

• Category breakdown: count per authorization type
• Recent authorizations: entities added in the last 6/12 months
• Cross-reference: if the user provided an entity name, check if it's on the regulated list

Workflow — other jurisdictions

Not every regulator exposes its register through OpenRegistry. Where native access isn't available, the skill tells the user:

• UK FCA Register: separate API, not covered by OpenRegistry. Use register.fca.org.uk directly.
• DE BaFin: BaFin database, separate. Not covered.
• FR ACPR / AMF: separate registers. Not covered.
• US SEC / FINRA / CFTC: SEC EDGAR / FINRA BrokerCheck / CFTC list — out of scope.

OpenRegistry covers government company registers. Financial-supervisor registers are separate systems. Where we pass-through data (CIMA, Korean DART for listed issuers), we use it.

Provenance & Auditability

CIMA records carry:

• CIMA reference number (e.g. 77003, 100088)
• Authorization type exactly as CIMA lists it
• Address as CIMA has it
• Status (active / surrendered / revoked) — CIMA's own enum

Every listed entity is one click from the CIMA Regulated Entities register for independent verification.

Jurisdictional scope

You might also need

• Once you've identified regulated entities, run DD on the top ones → KYC & Cross-Border Due Diligence
• Walk ownership of a regulated entity → Cross-Border UBO Chain Walker
• Compare competitive landscape → Industry & Competitor Company Search

Why the data stays fresh

CIMA updates its Regulated Entities register in near-real-time as licences are issued / surrendered / revoked; DART updates its corpCode master nightly. Our skill reflects updates the moment the regulator does. A licence granted this morning is in our result this afternoon.
