Scan and detect nearby Bluetooth devices via MCP

Bluetooth MCP Server

🔍 Overview

This project implements a Model Context Protocol (MCP) server that enables Claude and other AI assistants to scan and interact with Bluetooth devices in your vicinity. Built with a Test-Driven Development approach, it provides a robust, tested interface for Bluetooth operations across multiple platforms.

✨ Features

• 📡 Multi-protocol scanning: Detect both BLE and Classic Bluetooth devices
• 🔎 Flexible filtering: Filter devices by name, type, or other attributes
• 🔄 Automatic device recognition: Identify and categorize common devices (like Freebox, TVs, etc.)
• 📱 Enhanced device information: Get manufacturer info, device type, and detailed characteristics
• 🖥️ Cross-platform support: Works on Windows, macOS, and Linux
• ⚡ Platform-specific optimizations: Enhanced detection capabilities on Windows
• 🤖 MCP Integration: Seamless integration with Claude and compatible AI assistants

📋 Requirements

• Python 3.7+
• Bluetooth adapter (built-in or external)
• Admin/sudo privileges (required for some Bluetooth operations)
• Internet connection (for package installation)

🚀 Quick Start

Installation

# Clone the repository
git clone https://github.com/yourusername/bluetooth-mcp-server.git
cd bluetooth-mcp-server

# Create and activate virtual environment
python -m venv venv

# On Windows
venv\Scripts\activate
# On macOS/Linux
source venv/bin/activate

# Install dependencies
pip install -r requirements.txt

# Configure environment variables
cp .env.example .env
# Edit the .env file as needed

Running the Server

# Start the Bluetooth API server
python run.py

# In another terminal, start the MCP server
python bluetooth_mcp_server.py

Using with Claude

1. Expose your server to the internet using ngrok or deploy it to a server:

   ngrok http 8000
   

2. Configure Claude to use your MCP server:

   npx @anthropic-ai/sdk install-model-context-protocol <YOUR_SERVER_URL>
   

3. Ask Claude to scan for Bluetooth devices:

   Could you scan for nearby Bluetooth devices?

🔧 Troubleshooting

Bluetooth Issues

• "Access denied" errors: Run the server with admin/sudo privileges
• Adapter not detected: Ensure Bluetooth is enabled in your system settings
• No devices found: Make sure there are discoverable Bluetooth devices nearby
• Windows-specific issues: Check that Bluetooth services are active (services.msc)

MCP Issues

• Tool not detected by Claude: Verify your MCP server URL is correct and accessible
• Execution errors: Check the server logs for detailed error information
