run_gdscript · Godot Mcp Pilot MCP: Risk & Policy

WHAT IT DOES

What run_gdscript does on Godot Mcp Pilot

AI agents invoke run_gdscript to trigger actions in Godot Mcp Pilot. 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 run_gdscript needs a policy

This tool permits execution of arbitrary code within the Godot runtime environment. An AI agent misusing this could read/write files, modify game state, execute system calls via Godot's OS API, or trigger destructive operations on the project.

From the tool's definition run_gdscript runs arbitrary GDScript code ('Run a GDScript snippet headlessly') in the context of a Godot project. GDScript has full access to the Godot engine API, filesystem operations, and project state.

Verdict

run_gdscript Rate-limited

run_gdscript 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.

What risk level is run_gdscript? +

run_gdscript is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit run_gdscript? +

Yes. Add a rate_limit block to the run_gdscript 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.

How do I block run_gdscript completely? +

Set action: deny in the PolicyLayer policy for run_gdscript. 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.

What MCP server provides run_gdscript? +
