pyBittle-mcp-server

A Python MCP (Model Context Protocol) server for controlling the Bittle robot via Bluetooth. This server exposes a set of commands to move, pose, and interact with Bittle using the MCP protocol.

Features

• Connects to Bittle via Bluetooth
• Exposes movement and pose commands (forward, backward, turn, sit, rest, etc.)
• Integrates with MCP tools for remote and programmatic control
• Logs all activity to bittle_mcp.log

Requirements

• Python 3.10+
• uv for package management
• Bittle robot with Bluetooth enabled
• pyBittle library
• mcp-server library

Installation & Setup

1. Install uv (recommended for fast, reliable Python package management):

   curl -Ls https://astral.sh/uv/install.sh | sh
   

2. Install dependencies:

   uv pip install -r requirements.txt
   # or, if using pyproject.toml:
   uv pip install -r pyproject.toml
   

Usage

1. Configure Bluetooth: Ensure your Bittle robot is powered on and in Bluetooth pairing mode.

2. Run the MCP server:

   uv pip run python server.py
   

   The server will attempt to connect to Bittle and log status to bittle_mcp.log.

3. Integrate with MCP tools:

   • This server exposes commands via the MCP protocol, making them accessible to any MCP-compatible client or tool.
   • You can use the MCP CLI or other MCP tools to discover and invoke available commands on your Bittle robot.
   • Example (using MCP CLI):

     mcp call move_forward
     mcp call sit
     mcp call rest
     

   • All available commands are decorated with @mcp.tool() in server.py and are automatically registered with the MCP server.

Development

• The main logic is in server.py.
• Logging is configured to output to both console and bittle_mcp.log.
• Commands are decorated with @mcp.tool() for MCP exposure.

Troubleshooting

• If the server fails to connect, check Bluetooth pairing and ensure no other process is using the Bittle connection.
• Review bittle_mcp.log for detailed error messages.
