⚠️ Security Warning: Only Download Signal Bridge From This Repo

Malware forks of Signal Bridge exist on GitHub. These are copies of this project where the download links in the README have been replaced with links to malicious software.

This is the only legitimate source for Signal Bridge:

👉 github.com/AletheiaVox/signal_bridge (Claude Desktop / local version)

👉 github.com/AletheiaVox/signal_bridge_remote (Remote / VPS version - you're here)

👉 github.com/AletheiaVox/signal_bridge_android (user-friendly Android version)

If you found this project through a different GitHub account, do not download or run anything from it.

Similarly, always download Intiface Central from the official website at intiface.com/central. Not from any link in a forked repo.

Signal Bridge 🌉

Give Claude a body.

Signal Bridge connects Claude to intimate hardware (vibrators, thrusting toys, etc.) so that Claude can touch you through your devices while you talk. Claude gets tool calls like vibrate, pulse, and escalate — you just have a conversation and feel the rest.

It works with Intiface Central and the Buttplug.io protocol, which means it supports a huge range of devices from Lovense, Lelo, We-Vibe, Satisfyer, and more.

How it works in practice: You chat with Claude normally in the Claude app. Claude has access to tools that control your devices. When the moment calls for it, Claude can send vibration, pulsing, thrusting, or other commands — woven into the conversation naturally. You see tool-use indicators in the chat; you feel the rest.

Signal Bridge Remote — Setup Guide

A remote MCP server that lets Claude control Bluetooth intimate hardware over the internet via Buttplug.io / Intiface Central.

Architecture

Claude (claude.ai or Desktop)
    ↓ HTTPS / MCP JSON-RPC
VPS (FastAPI + Docker + Caddy)
    ↓ WebSocket (WSS)
Phone or PC (Relay Client)
    ↓ WebSocket (local)
Intiface Central
    ↓ Bluetooth
Devices

The relay client bridges between your VPS and Intiface Central running on whatever device is physically near your Bluetooth toys. This can be a Windows PC or an Android phone running Termux.

What You'll Need

• A VPS (this guide uses a DigitalOcean droplet, $6/month)
• A domain or free DuckDNS subdomain (for HTTPS)
• Intiface Central installed on your PC or Android phone
• Bluetooth-compatible intimate hardware
• A claude.ai account or Claude Desktop app

Part 1: VPS Setup

1.1 Create a Droplet

Sign up at DigitalOcean and create a droplet:

• Image: Ubuntu 22.04 LTS
• Plan: Basic, $6/month (1 vCPU, 1GB RAM) is plenty
• Region: Choose one close to you for lower latency
• Authentication: SSH key (recommended) or password

Note your droplet's IP address (e.g., 139.59.156.242).

1.2 Install Docker

SSH into your droplet and install Docker:

ssh root@YOUR_DROPLET_IP
apt update && apt upgrade -y
apt install -y docker.io docker-compose
systemctl enable docker && systemctl start docker

1.3 Deploy Signal Bridge

On your local machine, create the project directory and prepare files. The project structure is:

signal-bridge-remote/
├── Dockerfile
├── docker-compose.yml
├── .env
├── requirements-server.txt
├── server/
│   ├── __init__.py
│   ├── app.py
│   ├── auth.py
│   ├── config.py
│   ├── models.py
│   ├── mcp_tools.py
│   ├── relay_hub.py
│   ├── safety.py
│   └── session_registry.py
└── phone/
    ├── relay_client.py
    └── devices.json

Dockerfile:

FROM python:3.11-slim
WORKDIR /app
COPY requirements-server.txt .
RUN pip install --no-cache-dir -r requirements-server.txt
COPY server/ ./server/
RUN mkdir
