AI agents invoke pika_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 | — | Style name or ID (use pika_list_styles to browse options) |
motion | number | — | Motion intensity 1-4 (default: 2) |
prompt | string | Yes | Text description of the video to generate |
api_key | string | Yes | Pika API key |
duration | number | — | Video duration in seconds |
image_url | string | — | URL of an image to animate |
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 on the Pika platform. It executes a creative pipeline based on input arguments (text prompt and optional image), producing side effects on an external service. It is not purely a read, write, or destructive operation — it executes an external process and returns a job ID for polling.
From the tool's definition Generate a creative AI video from a text prompt using Pika. Optionally animate an input image. Returns a generation_id to poll for completion.

Attacks that exploit this kind of access
Generate a creative AI video from a text prompt using Pika. Optionally animate an input image. 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.
pika_generate_video accepts 9 parameters: seed, style, motion, prompt, api_key, duration, image_url, 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 pika_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.
pika_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 pika_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 pika_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.
pika_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.
