WHAT IT DOES

What android_close_app does on Dialogbrain

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

Parameter	Type	Required	Description
`package`	string	Yes	Android package name to close (e.g., 'com.whatsapp')
`channel_account_id`	integer	—	Android device channel_account ID. Omit when the workspace has a single Android device; REQUIRED when it has more than one (e.g. WhatsApp + LINE), else the call

Parameters from the server's own tool schema.

RISK

Why android_close_app is rated Medium

An AI agent can call android_close_app faster than any human can review: one bad instruction and it creates or modifies resources in Dialogbrain by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs android_close_app safely

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

android_close_app Rate-limited

android_close_app 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.

View as policy code

policy.json

  "tools": {
    "android_close_app": {
      "limits": [

          "counter": "android_close_app_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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