WHAT IT DOES

What unity_mppm_activate_scenario does on Unity MCP Server

AI agents invoke unity_mppm_activate_scenario to trigger actions in Unity 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.

RISK

Why unity_mppm_activate_scenario is rated High

Activating/loading a scenario triggers external operations in the Unity Editor (changing the active scenario state), which goes beyond simple data retrieval or writing. It executes a state change in the runtime environment. Severity is medium as misuse could disrupt the active project state but is generally reversible.

RECOMMENDED RULE

The rule that runs unity_mppm_activate_scenario safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unity MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unity_mppm_activate_scenario, this is the rule to start with:

unity_mppm_activate_scenario Rate-limited

unity_mppm_activate_scenario stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
