## Facts

- Tool: `click`
- Server: Chrome DevTools MCP (`anirbandz/chrome_mcp_devtool`) — https://policylayer.com/tools/anirbandz-chrome-mcp-devtool.md
- Homepage: https://github.com/Anirbandz/Chrome_MCP_DEVTOOL
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "click",
    "arguments": {}
  }
}
```

## Why click is rated High

Clicking a UI element is an external browser action whose effects are entirely argument-dependent. It could submit forms, trigger purchases, navigate pages, or invoke any browser-side behavior. This is a classic Execute-category action. Severity is medium because misuse could trigger unintended operations, but the blast radius depends heavily on context.

From the tool's own definition: "'Clicks on the provided element' — triggers a browser click action via Chrome DevTools Protocol, causing external side effects depending on what element is clicked (form submissions, navigation, UI interactions)."

## Use case

AI agents invoke click to trigger actions in Chrome DevTools MCP. 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Chrome DevTools MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "click": {
      "limits": [
        {
          "counter": "click_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
