Attacks that exploit this kind of access
The rule that runs create_plan safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Zype Com, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_plan, this is the rule to start with:
create_plan 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 Zype Com, apply this rule, and every create_plan call is checked against it from then on.
