Get all roles for a specific entity
AI agents call get_entity_roles to retrieve information from Norwegian Business Registry MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves organizational role information from the Norwegian Business Registry. It performs a read-only query operation with no side effects—it does not create, modify, delete, execute code, or trigger external actions. The data returned (roles associated with an entity) is business registry metadata that is already public.
From the tool's definition Tool name 'get_entity_roles' and description 'Get all roles for a specific entity' indicate a retrieval operation that queries existing data about entity roles without modification, deletion, or execution of code.

PolicyLayer is an MCP gateway — it sits between your AI agents and Norwegian Business Registry MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_entity_roles:
{
"version": "1",
"default": "deny",
"tools": {
"get_entity_roles": {}
}
} get_entity_roles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
