SensorMCP Server

A SensorMCP Model Context Protocol (MCP) Server that enables automated dataset creation and custom object detection model training through natural language interactions. This project integrates computer vision capabilities with Large Language Models using the MCP standard.

🌟 About

SensorMCP Server combines the power of foundation models (like GroundedSAM) with custom model training (YOLOv8) to create a seamless workflow for object detection. Using the Model Context Protocol, it enables LLMs to:

• Automatically label images using foundation models
• Create custom object detection datasets
• Train specialized detection models
• Download images from Unsplash for training data

[!NOTE] The Model Context Protocol (MCP) enables seamless integration between LLMs and external tools, making this ideal for AI-powered computer vision workflows.

✨ Features

• Foundation Model Integration: Uses GroundedSAM for automatic image labeling
• Custom Model Training: Fine-tune YOLOv8 models on your specific objects
• Image Data Management: Download images from Unsplash or import local images
• Ontology Definition: Define custom object classes through natural language
• MCP Protocol: Native integration with LLM workflows and chat interfaces
• Fixed Data Structure: Organized directory layout for reproducible workflows

Prerequisites

• uv for package management
• Python 3.13+ (uv python install 3.13)
• CUDA-compatible GPU (recommended for training)

Setup

1. Clone the repository:

git clone <repository-url>
cd sensor-mcp

2. Install dependencies:

uv sync

3. Set up environment variables (create .env file):

UNSPLASH_API_KEY=your_unsplash_api_key_here

🚀 Usage

Running the MCP Server

For MCP integration (recommended):

uv run src/zoo_mcp.py

For standalone web server:

uv run src/server.py

MCP Configuration

Add to your MCP client configuration:

{
    "mcpServers": {
        "sensormcp-server": {
            "type": "stdio",
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/sensor-mcp",
                "run",
                "src/zoo_mcp.py"
            ]
        }
    }
}
