WHAT IT DOES

What set_physics_fps does on Godot

AI agents use set_physics_fps 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
`fps`	integer	—	Physics ticks per second (default 60)

Parameters from the server's own tool schema.

RISK

Why set_physics_fps is rated Medium

This tool modifies a project/engine configuration setting (physics simulation tick rate). It is a reversible write operation — the value can be changed again — but misuse could destabilize physics simulations or game behavior. No code execution, deletion, or financial impact is implied.

RECOMMENDED RULE

The rule that runs set_physics_fps 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_fps, this is the rule to start with:

set_physics_fps Rate-limited

set_physics_fps 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.

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

FAQ

Questions about set_physics_fps

What does the set_physics_fps tool do? +

Set the physics simulation tick rate. 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_fps accept? +

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

How do I enforce a policy on set_physics_fps? +

Register the Godot MCP server in PolicyLayer and add a rule for set_physics_fps: 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_fps? +

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

Can I rate-limit set_physics_fps? +

Yes. Add a rate_limit block to the set_physics_fps 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_fps completely? +

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

set_physics_fps 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.
