rescale_model · Kiln MCP: Risk & Policy

WHAT IT DOES

What rescale_model does on Kiln

AI agents use rescale_model to create or update resources in Kiln — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kiln environment.

WHY IT NEEDS A POLICY

Why rescale_model needs a policy

Rescaling a model is a reversible modification (Write category) — it changes model dimensions but does not delete data or execute arbitrary code. The empty description lowers confidence; it's possible this operation could have side effects on a physical print job, but the most likely interpretation is a data modification operation. Severity is medium because misuse could corrupt or alter models queued for printing.

From the tool's definition Tool name 'rescale_model' suggests modifying a 3D model's scale/dimensions. Description is empty, providing no additional context.

Verdict

rescale_model Rate-limited

rescale_model 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.
