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