The most dangerous Openart tools

2 of Openart's 5 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

How to control Openart

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

Rate limit write operations
{
  "openart_create_character": {
    "limits": [
      {
        "counter": "openart_create_character_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "openart_get_character": {
    "limits": [
      {
        "counter": "openart_get_character_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

  1. Create a free account and register Openart — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about Openart

How do I prevent bulk modifications through Openart? +

The Openart server has 1 write tools including openart_create_character. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Openart.

How many tools does the Openart MCP server expose? +

5 tools across 2 categories: Read, Write. 3 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on Openart? +

Register the Openart 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 Openart tool call.
