MOST DANGEROUS TOOLS

High Risk

The most dangerous Quickchart tools

Write · Low create-barcode This tool creates and optionally writes barcode image data to files. Write · Low create-chart-using-apexcharts This tool creates visual chart artifacts and can write them to disk, making it a Write operation. Write · Low create-chart-using-chartjs This tool creates new chart artifacts and can save images to the file system. Write · Low create-chart-using-googlecharts This tool creates data artifacts (chart images) and can write them to the filesystem.

11 of Quickchart's 12 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Quickchart

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

Rate limit write operations

{
  "create-barcode": {
    "limits": [
      {
        "counter": "create-barcode_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get-visualization-tool-help": {
    "limits": [
      {
        "counter": "get-visualization-tool-help_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.

The Quickchart server has 11 write tools including create-barcode, create-chart-using-apexcharts, create-chart-using-chartjs. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour.
