Why humanizer_click needs a policy

This tool triggers a browser click action on a specified element, which is a browser interaction/execution operation. The effect depends on what element is clicked (could submit forms, trigger navigation, activate controls). In the context of a MITM proxy server with browser automation capabilities, misuse could lead to unintended interactions with web applications.

From the tool's definition Click an element. Pass one of: selector (CSS/XPath), role + optional name

POLICY

How to control humanizer_click

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

policy.json

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

humanizer_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 Proxy — 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 humanizer_click

What does the humanizer_click tool do? +

Click an element. Pass one of: selector (CSS/XPath), role + optional name,. It is categorised as a Execute tool in the Proxy MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on humanizer_click? +

Register the Proxy MCP server in PolicyLayer and add a rule for humanizer_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 Proxy. Nothing to install.

What risk level is humanizer_click? +

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

Can I rate-limit humanizer_click? +

Yes. Add a rate_limit block to the humanizer_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 humanizer_click completely? +

Set action: deny in the PolicyLayer policy for humanizer_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 humanizer_click? +

humanizer_click is provided by the Proxy MCP server (yfe404/proxy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Proxy tool call.

Start from Proxy, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
