rename_chain · Livepilot MCP: Risk & Policy

WHAT IT DOES

What rename_chain does on Livepilot

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

WHY IT NEEDS A POLICY

Why rename_chain needs a policy

An AI agent can call rename_chain faster than any human can review — one bad instruction and it creates or modifies resources in Livepilot by the hundred, each call as confident as the last.

Verdict

rename_chain Rate-limited

rename_chain 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.
