What bazel_ios_uninstall_app does on XcodeBazelMCP
AI agents call bazel_ios_uninstall_app to permanently remove resources in XcodeBazelMCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why bazel_ios_uninstall_app is rated Critical
Uninstalling an app is a destructive operation that cannot be undone—it removes the application and its associated data from the simulator permanently. While scoped to a simulator (limiting blast radius), it is still an irreversible deletion action. This is more severe than Write (which is reversible) and fits the Destructive category due to the inability to undo the operation without reinstalling.
From the tool's definition Tool name 'bazel_ios_uninstall_app' and description 'Uninstall an app from a simulator by bundle identifier' indicate irreversible removal of installed application data.
Attacks that exploit this kind of access
The rule that runs bazel_ios_uninstall_app safely

bazel_ios_uninstall_app 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 XcodeBazelMCP, apply this rule, and every bazel_ios_uninstall_app call is checked against it from then on.
