How do I use YOLO MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@YOLO MCP Server detect objects in this street photo" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Setup Instructions

Prerequisites

Python 3.10 or higher
Git (optional, for cloning the repository)

Environment Setup

Create a directory for the project and navigate to it:
```
mkdir yolo-mcp-service
cd yolo-mcp-service
```

Download the project files or clone from repository:

# If you have the files, copy them to this directory
# If using git:
git clone https://github.com/GongRzhe/YOLO-MCP-Server.git .

Create a virtual environment:

# On Windows
python -m venv .venv

# On macOS/Linux
python3 -m venv .venv

Activate the virtual environment:

# On Windows
.venv\Scripts\activate

# On macOS/Linux
source .venv/bin/activate

Run the setup script:
```
python setup.py
```
The setup script will:
- Check your Python version
- Create a virtual environment (if not already created)
- Install required dependencies
- Generate an MCP configuration file (mcp-config.json)
- Output configuration information for different MCP clients including Claude

Note the output from the setup script, which will look similar to:

MCP configuration has been written to: /path/to/mcp-config.json

MCP configuration for Cursor:

/path/to/.venv/bin/python /path/to/server.py

MCP configuration for Windsurf/Claude Desktop:
{
  "mcpServers": {
    "yolo-service": {
      "command": "/path/to/.venv/bin/python",
      "args": [
        "/path/to/server.py"
      ],
      "env": {
        "PYTHONPATH": "/path/to"
      }
    }
  }
}

To use with Claude Desktop, merge this configuration into: /path/to/claude_desktop_config.json

Downloading YOLO Models

Before using the service, you need to download the YOLO models. The service looks for models in the following directories:

The current directory where the service is running
A models subdirectory
Any other directory configured in the CONFIG["model_dirs"] variable in server.py

Create a models directory and download some common models:

# Create models directory
mkdir models

# Download YOLOv8n for basic object detection
curl -L https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n.pt -o models/yolov8n.pt

# Download YOLOv8n-seg for segmentation
curl -L https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n-seg.pt -o models/yolov8n-seg.pt

# Download YOLOv8n-cls for classification
curl -L https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n-cls.pt -o models/yolov8n-cls.pt

# Download YOLOv8n-pose for pose estimation
curl -L https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n-pose.pt -o models/yolov8n-pose.pt

For Windows PowerShell users:

# Create models directory
mkdir models

# Download models using Invoke-WebRequest
Invoke-WebRequest -Uri "https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n.pt" -OutFile "models/yolov8n.pt"
Invoke-WebRequest -Uri "https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n-seg.pt" -OutFile "models/yolov8n-seg.pt"
Invoke-WebRequest -Uri "https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n-cls.pt" -OutFile "models/yolov8n-cls.pt"
Invoke-WebRequest -Uri "https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n-pose.pt" -OutFile "models/yolov8n-pose.pt"

Configuring Claude

To use this service with Claude:

For Claude web: Set up the service on your local machine and use the configuration provided by the setup script in your MCP client.
For Claude Desktop:
- Run the setup script and note the configuration output
- Locate your Claude Desktop configuration file (the path is provided in the setup script output)
- Add or merge the configuration into your Claude Desktop configuration file
- Restart Claude Desktop

Using YOLO Tools in Claude

1. First Check Available Models

Always check which models are available on your system first:

</invoke>
</function_calls>

Troubleshooting

Camera Issues

If the camera doesn't work, try different camera IDs:

<function_calls>
<invoke name="start_camera_detection">
<parameter name="camera_id">1</parameter>  <!-- Try 0, 1, or 2 -->
</invoke>
</function_calls>

Model Not Found

If a model is not found, make sure you've downloaded it to one of the configured directories:

<function_calls>
<invoke name="get_model_directories">
</invoke>
</function_calls>

Performance Issues

For better performance with limited resources, use the smaller models (e.g., yolov8n.pt instead of yolov8x.pt)
