WHAT IT DOES

What CursorMove does on Android

AI agents invoke CursorMove 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
`times`	integer	—	The number of times to move the cursor in the specified direction
`direction`	string	Yes	The direction to move the cursor
`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 CursorMove is rated High

CursorMove performs a UI automation action on an Android device, repositioning the text cursor within input fields. This is an external operation that interacts with the device's state. While low-impact on its own, it constitutes an Execute action as it triggers device-level UI interactions. Misuse potential is low since it only moves a cursor without selecting, deleting, or entering text.

From the tool's definition 'Move the text cursor (caret) left or right within an input field or text area' — triggers a UI interaction/action on an Android device

RECOMMENDED RULE

The rule that runs CursorMove 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 CursorMove, this is the rule to start with:

CursorMove Rate-limited

CursorMove 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "CursorMove": {
      "limits": [
        {
          "counter": "cursormove_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

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

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

FAQ

Questions about CursorMove

What does the CursorMove tool do? +

CursorMove action, Move the text cursor (caret) left or right within an input field or text area. Use this to reposition the cursor without selecting text.. Parameters: direction (enum('left', 'right')) - The direction to move the cursor; times? (number) - The number of times to move the cursor in the specified direction. 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 CursorMove accept? +

CursorMove accepts 8 parameters: times, direction, android.deviceId, android.useScrcpy, android.aiActContext, android.waitAfterAction, android.replanningCycleLimit, android.screenshotShrinkFactor. Required: direction. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on CursorMove? +

Register the Android MCP server in PolicyLayer and add a rule for CursorMove: 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 CursorMove? +

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

Can I rate-limit CursorMove? +

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

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

CursorMove 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.
