clone_template · RendrKit MCP: Risk & Policy

WHAT IT DOES

What clone_template does on RendrKit

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

WHY IT NEEDS A POLICY

Why clone_template needs a policy

This tool creates a new resource (a cloned template with custom defaults) in the system. It is a reversible write operation — it doesn't delete or overwrite existing data, execute code, or involve financial transactions. Misuse could clutter the template library or create misleading presets, but the blast radius is moderate.

clone_template Rate-limited

clone_template 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.
