WHAT IT DOES

What set_time_signature does on Livepilot

AI agents use set_time_signature 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.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_time_signature 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 set_time_signature, this is the rule to start with:

set_time_signature Rate-limited

set_time_signature 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.
