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.

RISK

Why rename_chain is rated Medium

Renaming a chain is a reversible write operation—it modifies data (the chain's name) but does not delete or execute arbitrary operations. It falls under Write rather than Read (it modifies state) or Execute (it does not run code or trigger complex external effects).

From the tool's definition Tool name 'rename_chain' indicates modification of a chain object (likely an Ableton Live audio/MIDI chain). The description is empty, but the name clearly denotes a write operation that changes metadata/naming without deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs rename_chain safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Livepilot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rename_chain, this is the rule to start with:

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.

}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Livepilot, apply this rule, and every rename_chain call is checked against it from then on.

How do I enforce a policy on rename_chain? +

Register the Livepilot MCP server in PolicyLayer and add a rule for rename_chain: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Livepilot. Nothing to install.

What risk level is rename_chain? +

rename_chain is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit rename_chain? +

Yes. Add a rate_limit block to the rename_chain rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block rename_chain completely? +
