MOST DANGEROUS TOOLS

High Risk

The most dangerous Fourth Playwright MCP Server tools

Execute · High browser_wait_for Despite empty description, the tool name and server context indicate this controls browser behavior (waiting/blocking operations). Execute · High playwright_navigate This is a Playwright wrapper that navigates a browser to arbitrary URLs. Execute · High web_execute_js JavaScript execution in a browser is a classic Execute category risk. Execute · High web_navigate_and_wait Browser navigation is an Execute-category action because it triggers external side effects (loading arbitrary URLs, executing page scripts, state changes in the browser) that cannot be fully predicted without knowing the

10 of Fourth Playwright MCP Server's 24 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Fourth Playwright MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and Fourth Playwright MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "web_fill_form": {
    "limits": [
      {
        "counter": "web_fill_form_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "web_accessibility_audit": {
    "limits": [
      {
        "counter": "web_accessibility_audit_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
