THE RISK

Why right_click needs a policy

This tool performs a mouse interaction (right-click) on the macOS UI, triggering context menus and potentially executing any context menu actions. It is a direct UI control action with side effects depending on what is right-clicked, making it an Execute-category tool. Misuse could lead to triggering destructive or unintended operations via context menus on arbitrary applications.

From the tool's definition Right-click at specific coordinates to open context menus. Equivalent to click with button=

POLICY

How to control right_click

PolicyLayer is an MCP gateway — it sits between your AI agents and macOS Simulator MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for right_click:

policy.json

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

right_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.

Create a free account and register macOS Simulator MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about right_click

What does the right_click tool do? +

Right-click at specific coordinates to open context menus. Equivalent to click with button=. It is categorised as a Execute tool in the macOS Simulator MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on right_click? +

Register the macOS Simulator MCP Server MCP server in PolicyLayer and add a rule for right_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 macOS Simulator MCP Server. Nothing to install.

What risk level is right_click? +

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

Can I rate-limit right_click? +

Yes. Add a rate_limit block to the right_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 right_click completely? +

Set action: deny in the PolicyLayer policy for right_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 right_click? +

right_click is provided by the macOS Simulator MCP Server MCP server (ohqay/mac-commander). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
