AI agents invoke stability_text_to_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 |
|---|---|---|---|
seed | number | — | |
steps | number | — | Diffusion steps 10-150 (default: 30) |
width | number | — | |
height | number | — | |
prompt | string | Yes | |
api_key | string | Yes | |
samples | number | — | Number of images (max 10, default: 1) |
cfg_scale | number | — | Guidance scale 0-35 (default: 7) |
engine_id | string | — | Stability engine ID (default: stable-diffusion-xl-1024-v1-0) |
style_preset | string | — | |
negative_prompt | string | — |
Parameters from the server's own tool schema.
This tool triggers an external AI service (Stability AI) to generate images based on text input. It executes an operation on an external platform, consuming API credits and producing output that depends on the arguments. It is not a simple read, nor does it modify stored data in a reversible way — it invokes an external compute process.

Attacks that exploit this kind of access
Generate images from a text prompt using Stability AI. 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.
stability_text_to_image accepts 11 parameters: seed, steps, width, height, prompt, api_key, samples, cfg_scale, engine_id, style_preset, negative_prompt. 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 stability_text_to_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.
stability_text_to_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 stability_text_to_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 stability_text_to_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.
stability_text_to_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.
