flexsim_run_to_time · FlexSim MCP Server MCP: Risk & Policy

WHAT IT DOES

What flexsim_run_to_time does on FlexSim MCP Server

AI agents invoke flexsim_run_to_time to trigger actions in FlexSim MCP Server. 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 flexsim_run_to_time needs a policy

This tool triggers execution of the FlexSim simulation engine to advance to a specified time point. While reversible (simulations can be stopped or reset), it actively runs external operations (the simulation engine) whose side effects depend on the model configuration and current state.

From the tool's definition Tool name 'flexsim_run_to_time' and description '运行仿真到指定时间' (Run simulation to specified time) indicate the tool executes a simulation engine operation.
