rigidbody_set_properties

Tune a RigidBody2D/3D in the edited scene (undoable): mass (> 0), gravity_scale, linear_damp, angular_damp. Only the provided properties change. In-scene and undoable — not gated.

WHAT IT DOES

What rigidbody_set_properties does on Godot Breakpoint

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

RISK

Why rigidbody_set_properties is rated Medium

This tool creates or modifies data (physics properties of RigidBody objects) in a reversible manner—the description emphasizes it is 'undoable', making it a Write action rather than Destructive.

From the tool's definition Tool description explicitly states it "Tune[s] a RigidBody2D/3D" and modifies properties like "mass", "gravity_scale", "linear_damp", "angular_damp". It is marked as "undoable" and "In-scene", indicating reversible modifications to game object properties.

RECOMMENDED RULE

The rule that runs rigidbody_set_properties safely

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

rigidbody_set_properties Rate-limited

rigidbody_set_properties 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 Breakpoint, apply this rule, and every rigidbody_set_properties call is checked against it from then on.

FAQ

Questions about rigidbody_set_properties

What does the rigidbody_set_properties tool do? +

Tune a RigidBody2D/3D in the edited scene (undoable): mass (> 0), gravity_scale, linear_damp, angular_damp. Only the provided properties change. In-scene and undoable — not gated. It is categorised as a Write tool in the Godot Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on rigidbody_set_properties? +

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

What risk level is rigidbody_set_properties? +

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

Can I rate-limit rigidbody_set_properties? +

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

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

rigidbody_set_properties is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
