List addresses in a Norwegian municipality. Can filter by street name.
AI agents call no_municipality_addresses to retrieve information from Mcp Nordic without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves public address information from Norwegian municipality records. It performs a read-only query with optional filtering. There are no side effects, data modification, code execution, or irreversible operations. Public address data has minimal sensitivity compared to personal identifying information that might require higher classification, and the tool only supports retrieval.
From the tool's definition Tool name includes 'List addresses' and description indicates it 'returns' address data without modification. No delete, update, create, or execute operations are mentioned. Filtering by street name is a query parameter, not a data-altering operation.
