AI agents invoke xpath_long_press to trigger actions in uiautomator2 MCP Server. 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.
The tool name suggests performing a long press action on a UI element identified by XPath on an Android device. This is an Execute-category action as it triggers an external operation (UI interaction on a device). The description is empty, lowering confidence, but the name and server context strongly imply a device control action. Misuse could trigger unintended UI actions on a device.
From the tool's definition Tool name 'xpath_long_press' combined with server description about 'controlling Android devices' and 'automate tasks like tapping, swiping'
Documented attack patterns abuse exactly the kind of access xpath_long_press gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and uiautomator2 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for xpath_long_press:
{
"version": "1",
"default": "deny",
"tools": {
"xpath_long_press": {
"limits": [
{
"counter": "xpath_long_press_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}xpath_long_press 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.

xpath_long_press. It is categorised as a Execute tool in the uiautomator2 MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the uiautomator2 MCP Server MCP server in PolicyLayer and add a rule for xpath_long_press: 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 uiautomator2 MCP Server. Nothing to install.
xpath_long_press is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the xpath_long_press 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.
Set action: deny in the PolicyLayer policy for xpath_long_press. 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.
xpath_long_press is provided by the uiautomator2 MCP Server MCP server (tanbro/uiautomator2-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from uiautomator2 MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
