Exit game mode and return to edit mode.
AI agents invoke exit_game_mode to trigger actions in O3de. 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.
This tool triggers a state transition in the O3DE editor, switching from game mode back to edit mode. It executes an external operation (editor control) that changes the application state. While not destructive or financial, it's an action that affects the running environment rather than simply reading data or writing a file, making Execute the most appropriate category.

Documented attack patterns abuse exactly the kind of access exit_game_mode gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and O3de, and nothing reaches the server without passing your rules. This is the rule we recommend for exit_game_mode:
{
"version": "1",
"default": "deny",
"tools": {
"exit_game_mode": {
"limits": [
{
"counter": "exit_game_mode_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}exit_game_mode 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.

Exit game mode and return to edit mode. It is categorised as a Execute tool in the O3de MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the O3de MCP server in PolicyLayer and add a rule for exit_game_mode: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches O3de. Nothing to install.
exit_game_mode is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the exit_game_mode rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for exit_game_mode. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
exit_game_mode is provided by the O3de MCP server (nickschuetz/o3de-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from O3de, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
