What set_shape_points does on Godot
AI agents use set_shape_points 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 |
|---|---|---|---|
points | object | — | Points for polygon shapes |
radius | object | — | Radius for circle/capsule shapes |
extents | object | — | [width, height] for rectangle shapes |
node_path | string | Yes | Node path to CollisionShape2D or CollisionPolygon2D |
scene_path | string | Yes | Path to .tscn scene file |
shape_type | object | — | Shape type (for CollisionShape2D) |
Parameters from the server's own tool schema.
Why set_shape_points is rated Medium
This tool modifies collision shape data on a 2D game object in Godot. While it changes game state, it is reversible (can be set again to different values) and does not delete data or execute arbitrary code.
From the tool's definition Tool name 'set_shape_points' and description 'Set shape on CollisionShape2D' indicate modification of collision geometry properties. The verb 'set' denotes altering an existing game object's collision parameters, which is a reversible write operation.
Attacks that exploit this kind of access
The rule that runs set_shape_points 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_shape_points, this is the rule to start with:
set_shape_points 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_shape_points call is checked against it from then on.
Questions about set_shape_points
Set shape on CollisionShape2D. 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.
set_shape_points accepts 6 parameters: points, radius, extents, node_path, scene_path, shape_type. Required: node_path, scene_path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for set_shape_points: 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.
set_shape_points is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the set_shape_points 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 set_shape_points. 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.
set_shape_points is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
