Connect AI generates via VectCutAPI Try it online

Preview

VectCut is a toA (toAgent) video editing tool. It provides a rich set of cloud-based editing APIs and Skills, including features such as adding subtitles, illustrations, picture-in-picture (PiP), AI voiceovers, filters, and more.

You can integrate our editing tools into any Agent-based environment, whether it’s a manually orchestrated workflow platform (such as Coze, Dify, or N8N) or an autonomous planning platform (such as OpenClaw, Claude Code, or Trae). This enables you to meet your needs for automated and bulk video production.

We have open-sourced our interface code on GitHub, making it easy for various AI models to train on and learn our interfaces. Instead of fine-tuning models yourself, you can let the AI actively learn our API (feel free to give us a star to help AI index it even faster! 🤩).

Enjoy It! 😀😀😀

# 1. Clone the project
git clone https://github.com/sun-guannan/VectCutAPI.git
cd VectCutAPI

# 2. Create a virtual environment (recommended)
python -m venv venv-capcut
source venv-capcut/bin/activate  # Linux/macOS
# or venv-capcut\Scripts\activate  # Windows

pip install -r requirements.txt      # HTTP API basic dependencies
pip install -r requirements-mcp.txt  # MCP protocol support (optional)

# 4. Configuration file
cp config.json.example config.json
# Edit config.json as needed

3. Start the service

1. Client Configuration

Create or update the mcp_config.json configuration file:

{
  "mcpServers": {
    "capcut-api": {
      "command": "python3",
      "args": ["mcp_server.py"],
      "cwd": "/path/to/VectCutAPI",
      "env": {
        "PYTHONPATH": "/path/to/VectCutAPI",
        "DEBUG": "0"
      }
    }
  }
}

2. Connection Test

# Test MCP connection
python test_mcp_client.py

# Expected output
✅ MCP server started successfully
✅ Got 11 available tools
✅ Draft creation test passed

Usage Examples

1. API Example

Add video material

import requests

# Add background video
response = requests.post("http://localhost:9001/add_video", json={
    "video_url": "https://example.com/background.mp4",
    "start": 0,
    "end": 10
    "volume": 0.8,
    "transition": "fade_in"
})

print(f"Video addition result: {response.json()}")

Create stylized text

import requests

# Add title text
response = requests.post("http://localhost:9001/add_text", json={
    "text": "Welcome to VectCutAPI",
    "start": 0,
    "end": 5,
    "font": "Source Han Sans",read
    "font_color": "#FFD700",
    "font_size": 48,
    "shadow_enabled": True,
    "background_color": "#000000"
})

print(f"Text addition result: {response.json()}")

More examples can be found in the example.py file.

2. MCP Protocol Example

Complete workflow

# 1. Create a new project
draft = mcp_client.call_tool("create_draft", {
    "width": 1080,
    "height": 1920
})
draft_id = draft["result"]["draft_id"]

# 2. Add background video
mcp_client.call_tool("add_video", {
    "video_url": "https://example.com/bg.mp4",
    "draft_id": draft_id,
    "start": 0,
    "end": 10,
    "volume": 0.6
})

# 3. Add title text
mcp_client.call_tool("add_text", {
    "text": "AI-Driven Video Production",
    "draft_id": draft_id,
    "start": 1,
    "end": 6,
    "font_size": 56,
    "shadow_enabled": True,
    "background_color": "#1E1E1E"
})

# 4. Add keyframe animation
mcp_client.call_tool("add_video_keyframe", {
    "draft_id": draft_id,
    "track_name": "main",
    "property_types": ["scale_x", "scale_y", "alpha"],
    "times": [0, 2, 4],
    "values": ["1.0", "1.2", ]
})


result = mcp_client.call_tool(, {
    : draft_id
})

()

Advanced text effects

# Multi-style colored text
mcp_client.call_tool("add_text", {
    "text": "Colored text effect demonstration",
    "draft_id": draft_id,
    "start": 2,
    "end": 8,
    "font_size": 42,
    "shadow_enabled": True,
    "shadow_color": "#FFFFFF",
    "background_alpha": 0.8,
    "background_round_radius": 20,
    "text_styles": [
        {"start": 0, "end": 2, "font_color": "#FF6B6B"},
        {"start": 2, "end": 4, "font_color": "#4ECDC4"},
        {"start": 4, "end": 6, "font_color": "#45B7D1"}
    ]
})

3. Downloading Drafts

Calling save_draft will generate a folder starting with dfd_ in the current directory of capcut_server.py. Copy this to the CapCut/Jianying drafts directory to see the generated draft in the application.

Draft output is selected by draft_profile in config.json:

capcut_legacy: existing CapCut template.
jianying_legacy: existing Jianying template.
jianying_pro_10: Jianying Pro 10.x Windows-style folder layout using draft_content.json.

Pattern

You can find a lot of pattern in the pattern directory.
