create_pattern · Clo3d MCP: Risk & Policy

WHAT IT DOES

What create_pattern does on Clo3d

AI agents use create_pattern to create or update resources in Clo3d — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Clo3d environment.

WHY IT NEEDS A POLICY

Why create_pattern needs a policy

The tool appears to create garment patterns in CLO3D, which is a reversible design operation (patterns can be modified or deleted later). This falls under Write category rather than Execute because it modifies the design project data structure rather than executing arbitrary code.

From the tool's definition Tool name 'create_pattern' combined with server context of CLO3D garment design software; sibling tools include 'add_fabric', 'add_seam', and 'assign_fabric' which are clearly design operations. No description provided, limiting precision.

Verdict

create_pattern Rate-limited

create_pattern 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Clo3d, so you can run agents against it safely.

FAQ

Questions about create_pattern

What does the create_pattern tool do? +

create_pattern. It is categorised as a Write tool in the Clo3d MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_pattern? +

Register the Clo3d MCP server in PolicyLayer and add a rule for create_pattern: 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 Clo3d. Nothing to install.

What risk level is create_pattern? +

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

Can I rate-limit create_pattern? +

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

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

create_pattern is provided by the Clo3d MCP server (lilbonner/clo3d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
