WHAT IT DOES

What executar_lote does on Mcp Brasil

AI agents invoke executar_lote to trigger actions in Mcp Brasil. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why executar_lote needs a policy

The name 'executar_lote' means 'execute batch' in Portuguese, implying it runs multiple operations or queries in bulk. Given the server context involving 200+ tools across Brazilian public APIs, this likely executes a batch of API calls or queries. The description is empty, which lowers confidence. Batch execution tools can have significant blast radius if misused (e.g., firing many API requests).

From the tool's definition Tool name 'executar_lote' translates from Portuguese as 'execute batch', suggesting batch execution of multiple operations.
