Universal Robot MCP Server

A Model Context Protocol (MCP) server that provides AI assistants and LLM applications with secure, controlled access to Universal Robots functionality. This server enables real-time robot control, status monitoring, and motion planning through a standardized MCP interface.

Features

Robot Connection Management - Connect/disconnect from UR robots safely
Real-time Status Monitoring - Get joint positions, poses, and robot health
Joint Motion Control - Precise angular movement with safety limits
Linear Motion Control - Cartesian path planning and execution
Simulation Mode - Test and develop without physical hardware
Safety First - Built-in collision detection and movement validation

Installation

Quick Start with uvx (Recommended)

uvx universal-robot-mcp

Install via pip

pip install universal-robot-mcp

Development Installation

git clone https://github.com/RoversX/universal-robot-mcp
cd universal-robot-mcp
pip install -e .

Available Tools

| Tool | Description | Parameters | |------|-------------|------------| | connect_robot | Establish connection to UR robot | robot_ip (default: 192.168.1.100) | | disconnect_robot | Safely disconnect from robot | None | | get_robot_status | Get current joint positions and pose | None | | move_robot_joints | Move to specific joint angles | joint1-6, acceleration, velocity | | move_robot_linear | Linear movement in Cartesian space | x,y,z,rx,ry,rz, acceleration, velocity |

Example Conversations

Once configured with your AI assistant:

"Connect to the robot and show me its current status"
"Move the robot to home position safely"
"Execute a pick and place motion from coordinates X to Y"
"What are the current joint angles?"
"Move the robot 10cm up in the Z direction"
