MOST DANGEROUS TOOLS

High Risk

The most dangerous Web Bridge tools

Execute · Medium ClearInput ClearInput performs a browser/UI automation action that clears content from an input field. Execute · High Input This tool performs browser automation by inputting text into web form fields, triggering external UI interactions. Execute · High act This tool triggers execution of AI-planned multi-step operations based on natural language input. Execute · High KeyboardPress This tool triggers keyboard input actions in a browser automation context.

14 of Web Bridge's 15 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Web Bridge

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

Rate limit write operations

{
  "assert": {
    "limits": [
      {
        "counter": "assert_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "take_screenshot": {
    "limits": [
      {
        "counter": "take_screenshot_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on Web Bridge? +

Register the Web Bridge MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Web Bridge tool call.

Deterministic rules across all 15 Web Bridge tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
