thicken_mesh_walls · Kiln MCP: Risk & Policy

WHAT IT DOES

What thicken_mesh_walls does on Kiln

AI agents invoke thicken_mesh_walls to trigger actions in Kiln. 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 thicken_mesh_walls needs a policy

Based on the tool name alone, this appears to modify 3D mesh geometry by thickening wall structures, which is a Write/Execute operation in a 3D printing context. The empty description lowers confidence significantly. Given sibling tools like 'add_mesh_chamfer' and 'add_mesh_fillet' which are geometric modification operations, this likely falls into the Execute/Write category as it transforms mesh data.

From the tool's definition Tool name: 'thicken_mesh_walls'; description is empty and uninformative.
