Why browser_storage_list needs a policy

This tool queries browser storage data without creating, modifying, or deleting anything. It has no side effects and returns information only. The blast radius is minimal—an agent listing storage contents poses no direct harm, though the data retrieved could be sensitive (tokens, user data). Classified as Read with low severity since the tool itself performs only a query operation.

From the tool's definition Tool name and description: 'List all items in localStorage or sessionStorage' indicates retrieval-only operation with the verb 'list' and no modification capability.

How to control browser_storage_list

PolicyLayer is an MCP gateway — it sits between your AI agents and Termux Browser Pilot, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_storage_list:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_storage_list": {}
  }
}

browser_storage_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Termux Browser Pilot — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
