AI agents use create_primitive to create or update resources in Maya MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Maya MCP Server environment.
The tool creates 3D primitive objects in a Maya scene, which is reversible (can be deleted). This is a Write operation—it adds new data/geometry to the scene without executing arbitrary code or permanently destroying data. Severity is medium because unauthorized object creation could clutter scenes or cause confusion in collaborative workflows, but the effect is easily undone.
From the tool's definition Tool name 'create_primitive' and server context indicating 'object creation' in Autodesk Maya 3D modeling; sibling tools include destructive (delete_object), execution (execute_maya_code), and transformation operations (transform_object).
Documented attack patterns abuse exactly the kind of access create_primitive gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Maya MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_primitive:
{
"version": "1",
"default": "deny",
"tools": {
"create_primitive": {
"limits": [
{
"counter": "create_primitive_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_primitive 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.

create_primitive. It is categorised as a Write tool in the Maya MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Maya MCP Server MCP server in PolicyLayer and add a rule for create_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 Maya MCP Server. Nothing to install.
create_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_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_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_primitive is provided by the Maya MCP Server MCP server (jeffreytsai1004/maya-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Maya MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
