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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "generate_image",
    "arguments": {}

## Why generate_image is rated Medium

This tool creates new image files based on text prompts. It is a Write operation as it produces new artifacts (image files) stored via the server's file management system. It does not execute code, delete data, or involve financial transactions. Severity is medium because an AI agent could misuse it to generate inappropriate content or consume significant compute resources at scale.

From the tool's own definition: "'Generate single or multiple images from text prompts' - creates new image files from text input"

## Use case

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

## Recommended policy (PolicyLayer)

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

```json

  "tools": {
    "generate_image": {
      "limits": [
        {
          "counter": "generate_image_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
