Why create_crud_requests needs a policy

This tool generates request definitions within Bruno's API testing framework, which are reversible configurations that can be modified or deleted. It does not execute actual API calls, delete real data, or move funds—it only creates/modifies test request artifacts. Write category is appropriate since the tool creates new testing resources.

From the tool's definition Tool name 'create_crud_requests' and description 'Generate a complete set of CRUD operations for an entity' indicate it creates API request definitions (Write operations). CRUD includes Create, Read, Update, Delete request templates.

POLICY

How to control create_crud_requests

PolicyLayer is an MCP gateway — it sits between your AI agents and Bruno MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_crud_requests:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_crud_requests": {
      "limits": [
        {
          "counter": "create_crud_requests_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_crud_requests stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Bruno MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
