AI agents invoke higgsfield_generate_video 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 | — | Random seed for reproducibility |
style | string | — | Soul Style name (use higgsfield_get_styles to list available styles) |
prompt | string | Yes | Text description of the video to generate |
api_key | string | Yes | Higgsfield API key |
duration | number | — | Video duration in seconds |
aspect_ratio | string | — | e.g. 16:9, 9:16, 1:1 |
negative_prompt | string | — | What to avoid in the video |
Parameters from the server's own tool schema.
This tool triggers an external AI video generation operation. It executes a remote process (Higgsfield AI service) with effects that depend on the input prompt. It's not a simple read/write of stored data but an execution of an external computational service. Misuse could incur API costs or generate inappropriate content.

Attacks that exploit this kind of access
Generate a video from a text prompt using Higgsfield AI. Supports Soul Styles for cinematic looks. Returns a generation_id to poll for completion. 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.
higgsfield_generate_video accepts 7 parameters: seed, style, prompt, api_key, duration, aspect_ratio, 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 higgsfield_generate_video: 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.
higgsfield_generate_video 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 higgsfield_generate_video 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 higgsfield_generate_video. 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.
higgsfield_generate_video 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.
