🤖 HappyHorse 1.0 MCP Server

Use HappyHorse 1.0 as an MCP (Model Context Protocol) server, allowing AI assistants like Claude Desktop or Cursor to directly invoke HappyHorse generation tools.

Running the MCP Server

1. Ensure MUAPI_API_KEY is set in your environment.
2. Run the server:

   python3 mcp_server.py

3. To test with the MCP Inspector:

   npx -y @modelcontextprotocol/inspector python3 mcp_server.py

💻 Quick Start with HappyHorse 1.0 API (Python)

from happyhorse_api import HappyHorseAPI

# Initialize the HappyHorse 1.0 client
api = HappyHorseAPI()

# 1. Generate Video from Text (T2V)
print("Generating AI Video using HappyHorse 1.0...")
submission = api.text_to_video(
    prompt="A cinematic aerial shot of a coastal city at golden hour, waves crashing against cliffs, birds flying, 1080p",
    aspect_ratio="16:9",
    duration=10,
    quality="1080p"
)

# 2. Wait for completion
result = api.wait_for_completion(submission['request_id'])
print(f"Success! View your HappyHorse 1.0 video here: {result['outputs'][0]}")

---

🎵 Audio-Video Generation

HappyHorse 1.0's standout feature: jointly generating video and audio in a single Transformer forward pass.

from happyhorse_api import HappyHorseAPI

api = HappyHorseAPI()

# Generate video + audio together from text
submission = api.text_to_video_with_audio(
    prompt="A thunderstorm rolling over a mountain range, lightning flashing, thunder rumbling, rain pattering on leaves",
    aspect_ratio="16:9",
    duration=10,
    quality="1080p"
)

result = api.wait_for_completion(submission['request_id'])
print(f"Video with audio: {result['outputs'][0]}")

# Or use image-to-video with audio
submission = api.image_to_video_with_audio(
    prompt="@image1 comes alive — waves crashing, seagulls calling, ocean breeze",
    images_list=["https://example.com/beach.jpg"],
    aspect_ratio="16:9",
    duration=10,
)
result = api.wait_for_completion(submission['request_id'])
print(f"Animated image with audio: {result['outputs'][0]}")

Tip: Include explicit sound cues in your prompt (e.g. "crowd cheering", "piano melody", "engine roaring") for richer, more accurate audio generation.
