WHAT IT DOES

What uv_unwrap does on Blender Copilot MCP Server

AI agents use uv_unwrap 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.

RISK

Why uv_unwrap is rated Medium

UV unwrapping is a standard 3D modeling operation that alters mesh UV mapping (texture coordinates) but does not delete data or execute arbitrary code. It modifies the mesh state reversibly—the operation can be undone in Blender. This qualifies as Write rather than Execute because it performs a specific, bounded geometric transformation rather than running arbitrary logic.

From the tool's definition Tool description states 'UV unwrap a mesh' which modifies mesh data by generating UV coordinates. This is a reversible creation/modification operation on the 3D model's properties.

RECOMMENDED RULE

The rule that runs uv_unwrap 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 uv_unwrap, this is the rule to start with:

uv_unwrap Rate-limited

uv_unwrap 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 uv_unwrap call is checked against it from then on.

FAQ

Questions about uv_unwrap

What does the uv_unwrap tool do? +

UV unwrap a mesh using seam-based unwrapping. 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.

How do I enforce a policy on uv_unwrap? +

Register the Blender Copilot MCP Server MCP server in PolicyLayer and add a rule for uv_unwrap: 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.

What risk level is uv_unwrap? +

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

Can I rate-limit uv_unwrap? +

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

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

uv_unwrap is provided by the Blender Copilot MCP Server MCP server (dwgx/blender-copilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
