WHAT IT DOES

What higgsfield_generate_video does on UnClick

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
`model`	string	—	Optional Higgsfield model id when using the MCP account path
`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	—	Optional Higgsfield Cloud API key for this call. Omit it to use the connected Higgsfield MCP account login when available.
`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.

RISK

Why higgsfield_generate_video is rated High

This tool triggers an external video generation operation using AI, consuming subscription credits. It executes an external service call with real-world side effects (credit consumption, content generation). This falls under Execute as it runs an external operation whose effects depend on the prompt argument. Severity is high because misuse could drain subscription credits and generate unwanted content at scale.

From the tool's definition Generate a Higgsfield video from a prompt... uses subscription credits

RECOMMENDED RULE

The rule that runs higgsfield_generate_video safely

PolicyLayer is an MCP gateway: it sits between your AI agents and UnClick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For higgsfield_generate_video, this is the rule to start with:

higgsfield_generate_video Rate-limited

higgsfield_generate_video stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
