RECOMMENDED RULE

The rule that runs edit_script safely

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

edit_script Rate-limited

edit_script 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.
