AI agents invoke openai_generate_image to trigger actions in UnClick. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
n | number | — | Number of images to generate |
size | string | — | 1024x1024, 1792x1024, or 1024x1792 for DALL-E 3 |
model | string | — | dall-e-3 or dall-e-2 (default: dall-e-3) |
style | string | — | natural or vivid (DALL-E 3 only) |
prompt | string | Yes | |
api_key | string | Yes | |
quality | string | — | standard or hd (DALL-E 3 only) |
response_format | string | — | url or b64_json (default: url) |
Parameters from the server's own tool schema.
This tool triggers an external API call to OpenAI's DALL-E service to generate images based on text input. It executes an external operation with side effects (API consumption, potential cost). It is not purely Read since it creates new content via an external service.

Attacks that exploit this kind of access
Generate images from a text prompt using DALL-E. It is categorised as a Execute tool in the UnClick MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
openai_generate_image accepts 8 parameters: n, size, model, style, prompt, api_key, quality, response_format. Required: prompt, api_key. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for openai_generate_image: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches UnClick. Nothing to install.
openai_generate_image is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the openai_generate_image rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for openai_generate_image. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
openai_generate_image is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
