Get the table of contents structure for a municipality
AI agents call get_code_structure to retrieve information from MunicipalMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays structural information (table of contents) from existing municipal code documents. It is a read-only query operation with no side effects, no code execution, no data modification, and no destructive capability. The blast radius of misuse is minimal—an agent could only retrieve publicly available legal document metadata.
From the tool's definition Tool name 'get_code_structure' and description 'Get the table of contents structure for a municipality' indicate a retrieval operation that returns organizational metadata about municipal codes without modifying, executing, or deleting anything.
