# registry-mcp — national company registries (io.github.foretak/registry-mcp@0.3.0) > Source: > Published: 2026-09-07 15:28:35+00:00 [← Index](/leaderboard) # registry-mcp — national company registries The company registry MCP: brreg orgnr, Companies House, Bolagsverket organisationsnummer. The current version, v0.3.0, was published to the official MCP registry on 2026-09-07. It is distributed as registry-mcp on npm and as registry-mcp on PyPI and as a hosted remote over streamable-http, filed under Other by this index, and declares 6 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; [the index's current counts](/stats) put this record in context. ## Using registry-mcp — national company registries in Claude, Cursor, Gemini CLI, Cline, or Zed? MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and **HOLDs the call** when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use **Install this server** for that). Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less ``` uv tool install mcpindex-gate && mcpindex-config-wire ``` [method](/methodology) Semantic screen found no manipulation pattern in the description.

A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page. Own this server? [Screen its description →](/screen) ## That verdict was true at screening time (snapshot 2026-09-07). Contracts can change after screening, with no version bump. The gate pins registry-mcp — national company registries’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Unset means an anonymous client, which may be blocked upstream. `REGISTRY_MCP_CACHE_PATH` Path to the local SQLite response cache (24 h TTL). Defaults to ./data/cache.sqlite3. `COMPANIES_HOUSE_API_KEY` Companies House REST API key, required for the United Kingdom (GB). Free from developer.company-information.service.gov.uk. Unset means GB lookups return an upstream_error naming this variable; every other country still answers. `BOLAGSVERKET_CLIENT_ID` Bolagsverket OAuth 2 client id, required for Sweden (SE) together with BOLAGSVERKET_CLIENT_SECRET. Free, no contract: request both from Bolagsverket's kundanmälan form. Unset means SE lookups return an upstream_error naming both variables; every other country still answers. `BOLAGSVERKET_CLIENT_SECRET` Bolagsverket OAuth 2 client secret, the other half of BOLAGSVERKET_CLIENT_ID. Both are needed before Sweden (SE) can answer. `BOLAGSVERKET_ENVIRONMENT` Which Bolagsverket environment the Swedish credentials belong to: 'production' (default) or 'test'. It selects the data host and the token host as a pair, so the two can never be mixed. `REGISTRY_MCP_CONTACT_EMAIL` Contact address sent in the User-Agent to the national registry, as Brønnøysundregistrene asks of API clients.
