WHAT IT DOES

What android_install_apk does on Dialogbrain

AI agents use android_install_apk 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
`apk_url`	string	—	https URL of the APK — the server downloads it (preferred; the only practical option for real-sized apps).
`package`	string	—	Expected package name (for verification)
`reinstall`	boolean	—	Uninstall first if package exists (for different signature). OMIT for a normal install (default false).
`apk_base64`	string	—	APK as base64-encoded bytes. Only usable for tiny payloads (the whole blob is an LLM tool argument); prefer apk_url.
`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_install_apk is rated Medium

An AI agent can call android_install_apk 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_install_apk 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_install_apk, this is the rule to start with:

android_install_apk Rate-limited

android_install_apk 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

{
  "version": "1",
  "default": "deny",
  "tools": {
    "android_install_apk": {
      "limits": [
        {
          "counter": "android_install_apk_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_install_apk call is checked against it from then on.

FAQ

Questions about android_install_apk

What does the android_install_apk tool do? +

Install an app on the Android device from an APK or split bundle (XAPK/APKS — how most large modern apps ship). Provide apk_url (an https link the device downloads itself — preferred, and the only workable option for real apps) or, for tiny payloads, as apk_base64. Max 300MB. Large apps can take several minutes; if this call times out the install keeps running on the device — verify with the app-list tool instead of re-installing. Use reinstall=true to uninstall then install (for signature changes). It is categorised as a Write tool in the Dialogbrain MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does android_install_apk accept? +

android_install_apk accepts 5 parameters: apk_url, package, reinstall, apk_base64, channel_account_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on android_install_apk? +

Register the Dialogbrain MCP server in PolicyLayer and add a rule for android_install_apk: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Dialogbrain. Nothing to install.

What risk level is android_install_apk? +

android_install_apk is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit android_install_apk? +

Yes. Add a rate_limit block to the android_install_apk rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block android_install_apk completely? +

Set action: deny in the PolicyLayer policy for android_install_apk. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides android_install_apk? +

android_install_apk is provided by the Dialogbrain MCP server (https://api.dialogbrain.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
