WHAT IT DOES

What uv_pack_islands does on Blender Copilot MCP Server

AI agents use uv_pack_islands 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_pack_islands is rated Medium

UV packing reorganizes UV island coordinates within texture space but does not delete, destroy, or execute arbitrary operations. The effect is fully reversible (the original geometry and UVs remain; only their spatial arrangement in UV space changes). This is a data modification operation without side effects beyond the Blender scene, making it Write category rather than Execute.

From the tool's definition Tool name 'uv_pack_islands' and description 'Pack UV islands to fill UV space efficiently' indicate modification of UV mapping data in Blender, which is a reversible geometric transformation.

RECOMMENDED RULE

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

uv_pack_islands Rate-limited

uv_pack_islands 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.

What risk level is uv_pack_islands? +

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

Can I rate-limit uv_pack_islands? +

Yes. Add a rate_limit block to the uv_pack_islands 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_pack_islands completely? +
