AI agents invoke swipe_down 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 'swipe_down' strongly implies a UI gesture action on an Android device. Based on the server description explicitly mentioning 'swiping' as an automated task, this tool executes a swipe gesture on an Android device. The description is empty, which lowers confidence, but the context is clear.
From the tool's definition Tool name 'swipe_down' on a server described as providing tools for 'controlling Android devices using uiautomator2, enabling AI to automate tasks like tapping, swiping, and managing apps'
Documented attack patterns abuse exactly the kind of access swipe_down 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 swipe_down:
{
"version": "1",
"default": "deny",
"tools": {
"swipe_down": {
"limits": [
{
"counter": "swipe_down_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}swipe_down 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.

swipe_down. 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 swipe_down: 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.
swipe_down 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 swipe_down 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 swipe_down. 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.
swipe_down 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.
