What double_click does on Aos
AI agents invoke double_click to trigger actions in Aos. 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.
Why double_click is rated High
A double_click action triggers UI interactions on Android or Windows desktop environments. This is an Execute-category action as it performs external operations (UI automation) whose effects depend on where the click is directed. The description is empty, so confidence is reduced, but sibling tools and server context strongly imply this performs a double-click action in an automation context.
From the tool's definition Tool name 'double_click' on a server providing Android device and Windows desktop automation capability (MaaFramework-based MCP server). Sibling tools include 'click', 'connect_adb_device', 'connect_window' confirming UI automation context.
Attacks that exploit this kind of access
The rule that runs double_click safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Aos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For double_click, this is the rule to start with:
double_click 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Aos, apply this rule, and every double_click call is checked against it from then on.
Questions about double_click
double_click is a execute tool on the Aos MCP server. It is categorised as a Execute tool in the Aos MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Aos MCP server in PolicyLayer and add a rule for double_click: 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 Aos. Nothing to install.
double_click 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 double_click 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 double_click. 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.
double_click is provided by the Aos MCP server (@hybridlabor-api/aos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
