Lista todas as features (APIs) disponíveis no mcp-brasil.
AI agents call listar_features to retrieve information from Mcp Brasil without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about available features/APIs. It is a pure read operation with no side effects, no code execution, no data modification, and no destructive capability. The blast radius of misuse is minimal—an agent would only gain knowledge of what APIs exist, which is typically public information. Severity is low because discovering available APIs poses no direct risk.
From the tool's definition Tool name 'listar_features' and description 'Lista todas as features (APIs) disponíveis' indicate a listing/enumeration operation that retrieves metadata about available APIs without modifying or executing anything.
