RegenNexus MCP Server

MCP (Model Context Protocol) server adapter for RegenNexus UAP - enabling AI-controlled hardware.

This package exposes RegenNexus hardware capabilities as MCP tools, allowing Claude Code, Claude Desktop, and other MCP-compatible AI clients to control physical devices.

Features

  • Hardware Control: GPIO, PWM, robotic arms, sensors, cameras

  • Mesh Networking: Discover and communicate with nodes over LAN (UDP/WebSocket)

  • Serial/I2C: Communicate with microcontrollers and sensors

  • Two Connection Modes: Local (direct import) or Remote (HTTP API)

  • Auto-Discovery: Automatically detects installed RegenNexus and mesh nodes

  • MCP Compatible: Works with Claude, Codex, Gemini, and any MCP client

Installation

# MCP server only (for remote UAP connection) pip install regennexus-mcp # With local UAP support pip install regennexus-mcp[local] # With remote API support pip install regennexus-mcp[remote] # Everything pip install regennexus-mcp[all]

Quick Start

1. Configure Claude Code

Add to your Claude Code MCP settings:

{ "mcpServers": { "regennexus": { "command": "regennexus-mcp" } } }

2. Use with Claude

Once configured, Claude can control hardware:

User: "List all connected devices" Claude: [calls list_devices tool] User: "Turn on GPIO pin 18" Claude: [calls gpio_write with pin=18, value=1] User: "Move the robot arm to position [0, 45, -30, 0, 60, 0, 0]" Claude: [calls robot_arm_move with positions]

Configuration

Configure via environment variables:

# Connection mode: auto, local, or remote REGENNEXUS_MODE=auto # Remote mode settings REGENNEXUS_ENDPOINT=https://your-uap-server.com REGENNEXUS_API_KEY=your-api-key # Local mode settings REGENNEXUS_CONFIG=/path/to/regennexus-config.yaml # Logging REGENNEXUS_LOG_LEVEL=INFO

Claude Code Config with Environment

{ "mcpServers": { "regennexus": { "command": "regennexus-mcp", "env": { "REGENNEXUS_MODE": "local", "REGENNEXUS_LOG_LEVEL": "DEBUG" } } } }

Available Tools (Free Tier)

These tools are provided by the regennexus package (open source):

GPIO & Basic I/O

Tool

Description

gpio_write

Set a GPIO pin to HIGH (1) or LOW (0)

gpio_read

Read the current state of a GPIO pin

pwm_write

Set PWM duty cycle (0-100%) for motors, LEDs, servos

Sensors & I2C

Tool

Description

read_sensor

Read value from a sensor (temperature, humidity, etc.)

i2c_scan

Scan I2C bus for connected devices

Serial Communication

Tool

Description

serial_send

Send data over serial port (UART)

serial_read

Read data from serial port

Robotics

Tool

Description

robot_arm_move

Move a robotic arm to specified joint positions

gripper_control

Open or close a robotic gripper

Device Management

Tool

Description

list_devices

List all connected hardware devices

device_info

Get device details (CPU, memory, IP, temperature)

Camera

Tool

Description

camera_capture

Capture a single image from a camera

Mesh Network

Tool

Description

list_nodes

List all nodes in the mesh network

ping_node

Ping a node and measure network latency

send_to_node

Send a message/command to a specific node

broadcast_message

Broadcast a message to all nodes

find_by_capability

Find nodes with a specific capability

Premium tools with additional capabilities are available separately.

Connection Modes

Local Mode (Recommended)

Requires regennexus package installed on the same machine. Directly imports UAP modules for minimal latency. No API server needed.

pip install regennexus-mcp[local] REGENNEXUS_MODE=local regennexus-mcp

This is the recommended mode for most users.

Remote Mode (Advanced)

Connects to a UAP instance running as a service via HTTP API. Requires UAP API server to be running (regen server).

# On the UAP server machine: regen server --port 8080 # On the Claude Code machine: pip install regennexus-mcp[remote] REGENNEXUS_MODE=remote \ REGENNEXUS_ENDPOINT=http://uap-server:8080 \ regennexus-mcp

Auto Mode (Default)

Tries local first, falls back to remote if UAP not installed.

regennexus-mcp # Auto-detects best mode

Running Standalone

# Run MCP server regennexus-mcp # Or via Python python -m regennexus_mcp
