# registry-mcp — company data for AI agents, any country

One MCP server and one REST API over national business registries. Same JSON
from both surfaces. Live now: Norway (NO) — Enhetsregisteret /
Brønnøysundregistrene ("brreg"): organisasjonsnummer (orgnr) lookup, name
search, VAT registration status, and computed filing deadlines.

## Add it as an MCP server

    claude mcp add registry-mcp --transport http https://api.foretak.dev/mcp
    uvx registry-mcp      # local stdio server (Python)
    npx registry-mcp      # local stdio server (Node)

Tools: lookup_company(id, country="NO"), search_company(name, country="NO"),
company_deadlines(id, country, today), validate_company_id(id, country),
list_countries(). Resource: registry://rules/{country}.
Prompt: explain_company.

## Or call the REST API

    curl https://api.foretak.dev/v1/NO/company/923609016

Returns a CompanyReport: name, legal_form, status, vat_registered, vat_number,
addresses, industry_codes, employees, share_capital, plus confidence, cached,
fetched_at, source_url and license for citation. Unknown is null, never "" or 0.

Other routes: GET /v1/countries, GET /v1/{country}/search?q={name},
GET /v1/{country}/company/{id}/deadlines?today=YYYY-MM-DD,
GET /v1/{country}/validate/{id}, GET /health.

Errors are always {"error": {"code", "message", "hint"}}. The hint names the
next call you can make — read it before retrying.
