MOST DANGEROUS TOOLS

High Risk

Execute · Low stopwatch The tool performs an action that affects the interface state and user experience rather than merely retrieving data. Execute · Low timer Starting a timer is an action that triggers an interactive widget and initiates a time-based operation. Execute · Medium conversion Display a unit conversion widget that allows real-time conversion between multiple units. Each unit should contain a formula for each other

3 of Widget MCP's 4 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

HOW TO CONTROL WIDGET MCP

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

Cap read operations

{
  "display-fact": {
    "limits": [
      {
        "counter": "display-fact_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Create a free account and register Widget MCP — nothing to install.
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.
