## Why browser_localstorage_get is rated Low

This tool retrieves local storage data from a browser context. Retrieval operations have minimal blast radius—they expose data but do not modify, execute code, delete resources, or move money. Confidence is slightly reduced due to empty description, but the naming pattern is sufficiently clear.

From the tool's own definition: "Tool name 'browser_localstorage_get' indicates a retrieval operation on browser local storage. The 'get' suffix and read-only verb pattern are consistent with Read category tools like the sibling 'browser_cookie_get' and 'browser_console_messages'."

## Use case

AI agents call browser_localstorage_get to retrieve information from Playwright MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Playwright MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_localstorage_get": {}
  }
}
```
