RECOMMENDED RULE

The rule that runs sandbox_files_mkdir safely

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

sandbox_files_mkdir Rate-limited

sandbox_files_mkdir 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.
