click · Maa MCP: Risk & Policy

WHAT IT DOES

What click does on MaaMCP

AI agents invoke click to trigger actions in MaaMCP. 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 IT NEEDS A POLICY

Why click needs a policy

In the context of a desktop/mobile automation MCP server with sibling tools like double_click and click_key, 'click' almost certainly triggers a UI click action on a device or window. This is an Execute-category action as it drives external system behavior. The description is empty, reducing confidence, but the server context and sibling tools strongly imply UI automation.

From the tool's definition Tool name 'click' on a server described as providing 'Android device and Windows desktop automation capability' (Android 设备和 Windows 桌面自动化能力); sibling tools include 'double_click', 'click_key', 'connect_adb_device', 'connect_window'

Verdict

click Rate-limited

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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches MaaMCP, so you can run agents against it safely.

FAQ

Questions about click

What does the click tool do? +

click. It is categorised as a Execute tool in the MaaMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on click? +

Register the Maa MCP server in PolicyLayer and add a rule for 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 MaaMCP. Nothing to install.

What risk level is click? +

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

Can I rate-limit click? +

Yes. Add a rate_limit block to the 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.

How do I block click completely? +

Set action: deny in the PolicyLayer policy for 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.

What MCP server provides click? +

click is provided by the Maa MCP server (maa-ai/maamcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
