# Connect AI generates via CapCutAPI [Try it online](https://www.capcutapi.top)

## Project Overview
**CapCutAPI** is a powerful editing API that empowers you to take full control of your AI-generated assets, including images, audio, video, and text. It provides the precision needed to refine and customize raw AI output, such as adjusting video speed or mirroring an image. This capability effectively solves the lack of control often found in AI video generation, allowing you to easily transform your creative ideas into polished videos.

All these features are designed to mirror the functionalities of the CapCut software, ensuring a familiar and efficient editing experience in the cloud.

Enjoy It!  😀😀😀

### Advantages

1. **API-Powered Editing:** Access all CapCut/Jianying editing features, including multi-track editing and keyframe animation, through a powerful API.

2. **Real-Time Cloud Preview:** Instantly preview your edits on a webpage without downloads, dramatically improving your workflow.

3. **Flexible Local Editing:** Export projects as drafts to import into CapCut or Jianying for further refinement.

4. **Automated Cloud Generation:** Use the API to render and generate final videos directly in the cloud.

## Quick Start

### 1\. System Requirements

  - Python 3.10+
  - Jianying or CapCut International version
  - FFmpeg

### 2\. Installation and Deployment

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

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

# 3. Install dependencies
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

```bash
python capcut_server.py # Start the HTTP API server, default port: 9001

python mcp_server.py # Start the MCP protocol service, supports stdio communication
```

## MCP Integration Guide

[MCP 中文文档](https://www.google.com/search?q=./MCP_%E6%96%87%E6%A1%A3_%E4%B8%AD%E6%96%87.md) • [MCP English Guide](https://www.google.com/search?q=./MCP_Documentation_English.md)

### 1\. Client Configuration

Create or update the `mcp_config.json` configuration file:

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

### 2\. Connection Test

```bash
# 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

```python
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

```python
import requests

# Add title text
response = requests.post("http://localhost:9001/add_text", json={
    "text": "Welcome to CapCutAPI",
    "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

})

# 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", "0.8"]
})

print(f"Project saved: {result['result']['draft_url']}")
```

Advanced text effects

```python
# 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,

        {"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.

## Pattern

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

## Community & Support

We welcome contributions of all forms\! Our iteration rules are:

  - No direct PRs to main
  - PRs can be submitted to the dev branch
