RECOMMENDED RULE

The rule that runs adb_webview_attach safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For adb_webview_attach, this is the rule to start with:

adb_webview_attach Rate-limited

adb_webview_attach stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

          "max": 10,

        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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