Cobot Server

This repository contains the MCP Cobot Server, a FastMCP server implementation for the M5 MyCobot280 robot.

Based on the model context protocol python-sdk: https://github.com/modelcontextprotocol/python-sdk?tab=readme-ov-file#quickstart

Features

• Implements the MCP standard for efficient context management.
• Built with FastMCP for high performance and scalability.
• Designed for integration with collaborative robot (myCobot) systems.

Requirements

• Python 3.8+
• FastMCP library

Installation

1. Clone the repository:

   git clone https://github.com/your-username/mcp-cobot-server.git
   cd mcp-cobot-server
   

2. Install dependencies:

   uv sync
   source .venv/bin/activate
   

Note This project uses uv to install manage the python virtual environment and dependencies. Learn more here: https://docs.astral.sh/uv/guides/projects/

Usage

Start the server:

# launch a standalone MCP server with:
uvx mcpo --port 8000 -- uv run --with mcp[cli] --with pymycobot mcp run ./server.py

# Install the mcp profile with claude
mcp install server.py

For development:

# debug the mcp interface
mcp dev server.py

Available Functions

The following functions are exposed to mcp.tool in server.py:

1. get_angles: Retrieves the current angles of all servos.
2. move_angle: Moves a specific joint (servo) to a target angle at a specified speed.
3. move_angles: Moves all joints to specified angles at a given speed.
4. go_home: Moves all joints to a predefined "home" position.
5. set_home: Sets the current joint angles as the new "home" position.
6. change_color: Changes the LED matrix color of the robot.
7. relax: Releases all servos, allowing the robot arms to relax.
8. interpretive_dance_routine: Executes a creative dance routine based on a description, involving joint movements and LED color changes.
