flexsim_launch · FlexSim MCP Server MCP: Risk & Policy

WHAT IT DOES

What flexsim_launch does on FlexSim MCP Server

AI agents invoke flexsim_launch 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_launch needs a policy

Launching a FlexSim process is an executable action that initiates a third-party application with effects dependent on system state and subsequent commands. This falls squarely into the Execute category as it runs an external operation whose outcomes depend on what commands follow.

From the tool's definition Tool name 'flexsim_launch' and description '启动 FlexSim 进程' (Start FlexSim process) indicate launching an external application process, which is an Execute operation that triggers external system behavior.
