What store_upload does on Claude Mobile
AI agents use store_upload 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.
Why store_upload is rated Medium
This tool uploads app packages to Google Play Store, which is a write operation creating/publishing new content to an external platform. It is not directly financial but has high blast radius since publishing a malicious or incorrect app to Google Play could affect many users. It is reversible in the sense that apps can be unpublished, so Destructive is not the best fit. Write is the most appropriate category.

The rule that runs store_upload 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 store_upload, this is the rule to start with:
store_upload 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 Claude Mobile, apply this rule, and every store_upload call is checked against it from then on.
