Configuration

Variable	Required	Secret	Description
REGISTRY_MCP_CONTACT_EMAIL	—	—	Contact address sent in the User-Agent to the national registry, as Brønnøysundregistrene asks of API clients. Unset means an anonymous client, which may be blocked upstream.
COMPANIES_HOUSE_API_KEY	—	yes	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	—	yes	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	—	yes	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_CACHE_PATH	—	—	Path to the local SQLite response cache (24 h TTL). Defaults to ./data/cache.sqlite3.
