AI agents call get_deputado to retrieve information from Openar without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves public information about a deputy (member of parliament) including their mandates and recent initiatives. It performs no data modification, deletion, code execution, or financial transaction. The data appears to be from an open public legislative database. This is a straightforward Read operation with minimal risk.
