tris_to_quads · Blender MCP: Risk & Policy

WHAT IT DOES

What tris_to_quads does on BlenderMCP

AI agents invoke tris_to_quads to trigger actions in BlenderMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why tris_to_quads needs a policy

Based on the tool name, 'tris_to_quads' likely converts triangular faces to quad faces in a Blender mesh — a mesh modification operation. This is a Write/Execute level action (modifying geometry in Blender). Given the context of sibling tools (modifiers, mesh operations, Python script execution in Blender), this likely executes a Blender operation that modifies mesh topology.

From the tool's definition Tool name 'tris_to_quads' and empty description; sibling tools suggest this is a Blender mesh operation
