WHAT IT DOES

What Terminate does on Android

AI agents invoke Terminate to trigger actions in Android. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

Parameter	Type	Required	Description
`uri`	string	Yes	Package name or app name to terminate. Use the exact package name, e.g. com.android.settings.
`android.deviceId`	string	—	Android device ID (from adb devices)
`android.useScrcpy`	boolean	—	Enable scrcpy accelerated screenshots
`android.aiActContext`	string	—	Background knowledge passed to aiAct. Default: no extra context.
`android.waitAfterAction`	number	—	Wait time in milliseconds after each action execution. Default: 300ms.
`android.replanningCycleLimit`	integer	—	Maximum number of replanning cycles for aiAct. Default: model adapter default.
`android.screenshotShrinkFactor`	number	—	Screenshot shrink factor before sending images to AI. Default: 1; high values may reduce recognition quality, especially on mobile.

Parameters from the server's own tool schema.

RISK

Why Terminate is rated High

This tool force-stops a running Android application, which is an external operation that terminates a process. It is not merely reading data, and while disruptive, it does not irreversibly delete data — the app can be relaunched. It falls under Execute as it triggers an external system operation (force-stop) whose effects depend on the package name argument.

RECOMMENDED RULE

The rule that runs Terminate safely

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

Terminate Rate-limited

Terminate 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.

FAQ

Questions about Terminate

What does the Terminate tool do? +

Terminate action, Terminate (force-stop) an Android app by package name. Parameters: uri (string) - Package name or app name to terminate. Use the exact package name, e.g. com.android.settings. It is categorised as a Execute tool in the Android MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

What parameters does Terminate accept? +

Terminate accepts 7 parameters: uri, android.deviceId, android.useScrcpy, android.aiActContext, android.waitAfterAction, android.replanningCycleLimit, android.screenshotShrinkFactor. Required: uri. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on Terminate? +

Register the Android MCP server in PolicyLayer and add a rule for Terminate: 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 Android. Nothing to install.

What risk level is Terminate? +

Terminate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit Terminate? +

Yes. Add a rate_limit block to the Terminate 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 Terminate completely? +

Set action: deny in the PolicyLayer policy for Terminate. 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 Terminate? +

Terminate is provided by the Android MCP server (@midscene/android-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
