WHAT IT DOES

What click does on Chrome Devtools

AI agents invoke click to trigger actions in Chrome Devtools. 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.

RISK

Why click is rated High

Clicking an element is a browser action that executes an interaction with external state. Its effects are argument-dependent and can range from benign navigation to triggering destructive or financial operations (form submissions, button presses). Per the rules, Execute covers browser actions whose effects depend on arguments.

From the tool's definition Tool name 'click' and description 'Clicks on the provided element' — triggers a browser UI action that interacts with external web content, whose effects depend entirely on what element is clicked (e.g., submitting forms, navigating pages, triggering…

RECOMMENDED RULE

The rule that runs click safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Chrome Devtools, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For click, this is the rule to start with:

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.

  "version": "1",
  "default": "deny",

    "click": {
      "limits": [

          "window": "minute",
          "max": 10,

        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Chrome Devtools, apply this rule, and every click call is checked against it from then on.

FAQ

Questions about click

What does the click tool do? +

Clicks on the provided element. It is categorised as a Execute tool in the Chrome Devtools 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 Chrome Devtools 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 Chrome Devtools. 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 Chrome Devtools MCP server (@async23/chrome-devtools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
