AI agents use create_mesh_primitive 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 |
|---|---|---|---|
path | string | Yes | Output path for mesh .tres |
params | object | — | Override default size params |
mesh_type | string | Yes |
Parameters from the server's own tool schema.
This tool creates (writes) new mesh resources to the Godot engine. While creation operations are reversible (the mesh can be deleted), they do modify project state and are more intrusive than simple read operations. It does not execute arbitrary code, delete data irreversibly, or handle financial transactions.
From the tool's definition The tool 'create_mesh_primitive' creates a 3D mesh resource (Box, Capsule, Cylinder, Plane, Sphere, Torus, etc.), which is a persistent creation operation that modifies the Godot project state by adding new mesh assets.

Attacks that exploit this kind of access
Create 3D mesh resource: Box, Capsule, Cylinder, Plane, Sphere, Torus, etc. (11 types). 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.
create_mesh_primitive accepts 3 parameters: path, params, mesh_type. Required: path, mesh_type. 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 create_mesh_primitive: 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.
create_mesh_primitive 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 create_mesh_primitive 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 create_mesh_primitive. 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.
create_mesh_primitive 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.
create_mesh_primitive is one line of Godot's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
