What create_metal does on Blender Copilot MCP Server
AI agents use create_metal to create or update resources in Blender Copilot MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Blender Copilot MCP Server environment.
Why create_metal is rated Medium
This tool modifies object properties in Blender by applying material attributes. It is reversible (materials can be removed or changed), so it qualifies as Write rather than Destructive. The severity is medium because misuse could alter a scene's appearance and require manual correction, but the changes are not irreversible and have limited blast radius in a 3D creation context.
From the tool's definition The tool applies a metallic material to an object, modifying the object's appearance properties in Blender. The description 'Apply a metallic material to an object' indicates a creation/modification action.
Attacks that exploit this kind of access
The rule that runs create_metal safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Blender Copilot MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_metal, this is the rule to start with:
create_metal 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 Blender Copilot MCP Server, apply this rule, and every create_metal call is checked against it from then on.

Apply a metallic material to an object. Default is silver-ish. It is categorised as a Write tool in the Blender Copilot MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Blender Copilot MCP Server MCP server in PolicyLayer and add a rule for create_metal: 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 Blender Copilot MCP Server. Nothing to install.
create_metal 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_metal 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_metal. 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.
