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

How to control OpenAPI MCP Gateway

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

Cap read operations
{
  "get_operation": {
    "limits": [
      {
        "counter": "get_operation_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 OpenAPI MCP Gateway — 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.
