set_colorway · Clo3d MCP: Risk & Policy

WHAT IT DOES

What set_colorway does on Clo3d

AI agents use set_colorway to create or update resources in Clo3d — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Clo3d environment.

WHY IT NEEDS A POLICY

Why set_colorway needs a policy

This tool creates or modifies data (a colorway's name and/or active status) but does not delete, execute external commands, move money, or irreversibly destroy content. The changes can be undone by setting a different colorway current or renaming it again.

From the tool's definition Tool description states 'Make a colorway current, optionally renaming it' — this modifies the state of a colorway object by changing its current status and/or name, which are reversible changes to design data within CLO3D.

Verdict

set_colorway Rate-limited

set_colorway 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.
