hacer_intento · Fast MCP: Risk & Policy

WHAT IT DOES

What hacer_intento does on FastMCP

AI agents invoke hacer_intento to trigger actions in FastMCP. 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 hacer_intento needs a policy

This tool sends/submits a value and receives a response, implying an interactive game-like operation (likely related to 'iniciar_partida'). It triggers an external check/operation rather than purely reading data, making Execute the best fit. Severity is low as it appears to be a simple number-guessing game with no destructive or financial implications. Confidence is moderate due to the brief, informal description.

From the tool's definition 'Envía un número para ver si es el correcto' — submits a number to check if it is correct
