## Use this model from an AI agent

Atlas Cloud ships three first-party integration surfaces. All three authenticate
with the same API key via the `ATLASCLOUD_API_KEY` environment variable.

### MCP server

The official MCP server (`atlascloud-mcp`) exposes this model to any
MCP-compatible host — Claude Code, OpenAI Codex, Cursor, Gemini CLI, Goose,
Claude Desktop. One-line install:

```bash
# Claude Code
claude mcp add atlascloud -- npx -y atlascloud-mcp

# OpenAI Codex CLI
codex mcp add atlascloud -- npx -y atlascloud-mcp

# Gemini CLI
gemini mcp add atlascloud -- npx -y atlascloud-mcp

export ATLASCLOUD_API_KEY="your-api-key"
```

Then ask in plain English; the agent calls `atlas_generate_video` with `model: "kwaivgi/kling-v1.6-i2v-standard"`.
The server fetches each model's schema and validates parameters before submitting,
so invalid requests fail fast without spending credits.

### Agent Skills

`atlas-cloud-skills` is a portable skill package (API reference, code templates in
Python / Node.js / cURL, model IDs with pricing) for Claude Code, Cursor, Codex and
12+ other agents:

```bash
npx skills add AtlasCloudAI/atlas-cloud-skills
export ATLASCLOUD_API_KEY="your-api-key"
```

Skills docs: https://www.atlascloud.ai/docs/skills

### CLI

The `atlas` binary runs Atlas Cloud from a terminal or CI script. Async media jobs
are polled and downloaded automatically (use `--no-download` when a script only
needs the output URLs):

```bash
# Install (Homebrew, npm, or shell installer)
brew install AtlasCloudAI/tap/atlascloud
# npm install -g atlascloud-cli
# curl -fsSL https://raw.githubusercontent.com/AtlasCloudAI/cli/main/install.sh | sh

atlas auth login
atlas generate video kwaivgi/kling-v1.6-i2v-standard -p "Your prompt here"
```

CLI docs: https://www.atlascloud.ai/docs/cli

### Kling-V1.6-i2v-Standard

Kling-V1.6-i2v-Standard is an AI image-to-video generation model developed by the Kuaishou AI Team, now available on WaveSpeedAI. It transforms static images into dynamic 5-second videos at 720p resolution, offering high-quality visual outputs with enhanced motion and semantic understanding.

#### Key Features

*   **High-Quality Video Output**: Generates 5-second videos at 720p resolution with vivid details and cinematic quality.
*   **Enhanced Motion Rendering**: Utilizes advanced dynamic rendering techniques to create smooth and natural movements.
*   **Improved Semantic Understanding**: Excels in interpreting complex user prompts to generate coherent and dynamic scenes.
*   **Physical Realism**: Simulates realistic physical properties and movements for lifelike videos.
*   **Fast Processing**: Optimized for efficient generation, allowing quick creation of high-quality videos.
*   **Customizable Parameters**: Offers adjustable settings such as duration, quality, and style for greater control over outputs.

#### Limitations

*   **Creative Focus**: Designed primarily for creative video synthesis; not intended for generating factually accurate content.
*   **Inherent Biases**: Outputs may reflect biases present in the training data.
*   **Input Sensitivity**: The quality and consistency of generated videos depend significantly on the quality of the input image; subtle variations may lead to output variability.
*   **Resolution Limitation**: This model is optimized for 720p video generation and does not support higher resolutions like 1080p.

#### Out-of-Scope Use

The model and its derivatives may not be used in any way that violates applicable national, federal, state, local, or international law or regulation, including but not limited to:
