AI agents call get_votacao 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.

It performs a read-only operation on public parliamentary records, presenting vote details and party voting patterns. There are no side effects, data modifications, or irreversible actions. The low severity reflects that misuse would only expose publicly available legislative information.
