WHAT IT DOES

What file_push does on Claude Mobile

AI agents use file_push to create or update resources in Claude Mobile, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Mobile environment.

RISK

Why file_push is rated Medium

File upload is a Write operation because it creates or modifies data on the target device. Severity is high because uploading arbitrary files to a mobile device could enable malicious payloads, credential theft, or compromise of sensitive applications, though the impact depends on file content and device permissions.

From the tool's definition Tool description states 'Upload file to Aurora OS device' - this creates or modifies files on a mobile device. The operation is reversible (files can be deleted), distinguishing it from Destructive actions.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs file_push 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 file_push, this is the rule to start with:

file_push Rate-limited

file_push 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.

      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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