WHAT IT DOES

What uv_mark_seams does on Blender Copilot MCP Server

AI agents use uv_mark_seams 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_mark_seams is rated Medium

The tool performs UV seam marking, which creates or modifies UV seam data on 3D model geometry. This is a Write operation because it alters model data reversibly. Severity is medium because incorrect seam marking could require rework but doesn't cause irreversible loss or execute arbitrary code.

From the tool's definition Tool name 'uv_mark_seams' indicates modification of UV seams in Blender 3D models. UV seam marking is a reversible edit operation that modifies model metadata/topology tags without destroying data.

RECOMMENDED RULE

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

uv_mark_seams Rate-limited

uv_mark_seams 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.
