Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs layout_preset safely

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

layout_preset Rate-limited

layout_preset 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.

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