## Facts

- Tool: `click`
- Server: Chrome Devtools (`@async23/chrome-devtools-mcp`) — https://policylayer.com/tools/async23-chrome-devtools-mcp.md
- Install: `npx -y @async23/chrome-devtools-mcp`
- Homepage: https://github.com/Async23/chrome-devtools-mcp
- 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 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 own 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…"

## Use case

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.

## Recommended policy (PolicyLayer)

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

```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`
