What sync_destroy does on Claude Mobile
AI agents call sync_destroy to permanently remove resources in Claude Mobile, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why sync_destroy is rated Critical
This tool performs an irreversible operation that cannot be undone. Destroying a sync group likely removes synchronization settings, group associations, or shared state that cannot be recovered without manual reconfiguration. While not as critical as data deletion across files, the permanent removal of a configured system component (sync group) with resource deallocation qualifies as Destructive.
From the tool's definition Tool name is 'sync_destroy' with description 'Destroy a sync group and release resources.' The verb 'destroy' combined with 'release resources' indicates irreversible deletion or deallocation of a sync group configuration or data structure.
Attacks that exploit this kind of access
The rule that runs sync_destroy safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Mobile, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sync_destroy, this is the rule to start with:
sync_destroy is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Claude Mobile, apply this rule, and every sync_destroy call is checked against it from then on.
