WHAT IT DOES

What set_physics_engine does on Godot

AI agents use set_physics_engine to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.

Parameter	Type	Required	Description
`engine`	string	Yes	Physics engine backend

Parameters from the server's own tool schema.

RISK

Why set_physics_engine is rated Medium

This tool modifies a project-level configuration setting (the physics engine backend). It is a reversible write operation — the setting can be changed again. Misuse could cause physics simulations to break or behave unexpectedly in a Godot project, but it does not delete data or execute arbitrary code.

RECOMMENDED RULE

The rule that runs set_physics_engine safely

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

set_physics_engine Rate-limited

set_physics_engine stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every set_physics_engine call is checked against it from then on.

FAQ

Questions about set_physics_engine

What does the set_physics_engine tool do? +

Set which physics engine backend to use. It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does set_physics_engine accept? +

set_physics_engine accepts 1 parameter: engine. Required: engine. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on set_physics_engine? +

Register the Godot MCP server in PolicyLayer and add a rule for set_physics_engine: 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 Godot. Nothing to install.

What risk level is set_physics_engine? +

set_physics_engine is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_physics_engine? +

Yes. Add a rate_limit block to the set_physics_engine 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 set_physics_engine completely? +

Set action: deny in the PolicyLayer policy for set_physics_engine. 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 set_physics_engine? +

set_physics_engine is provided by the Godot MCP server (@keeveeg/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
