## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "create_field",
    "arguments": {
      "name": "<name>",
      "app_id": "<app_id>"
    }
  }
}
```

## Why create_field is rated Medium

The tool creates new fields in database forms, which modifies the database schema reversibly. This is a Write operation (schema modification) rather than destructive since fields can be removed or modified later. Severity is medium because unintended field creation could clutter databases or expose unintended data structures, but the impact is containable.

From the tool's own definition: "Tool description states 'Додати поле до форми' (Add field to form) and lists various field types that can be added. This is a create/modify operation on form schema."

Risk signals: Accepts URL/endpoint input (action_tasks[].webhook) · High parameter count (116 properties)

## Use case

AI agents use create_field to create or update resources in QuintaDB, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your QuintaDB environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches QuintaDB:
