PCBridge

Use your computer like a coding agent — from any AI chatbot.

PCBridge is a web-hosted MCP bridge that lets ChatGPT, Claude, Gemini, and other compatible chatbots execute code, edit files, run commands, and use Git on your computer through a secure connection.

How It Works

┌─────────────────┐     ┌──────────────────┐     ┌─────────────────┐
│   AI Chatbot    │────▶│  PCBridge Cloud  │────▶│  Your Computer  │
│ (ChatGPT, etc.) │◀────│  (Vercel + MCP)  │◀────│  (Local Runner) │

1. Cloud (pcbridge.vercel.app): Hosts the dashboard, MCP gateway, and request routing

2. Local Runner: Lightweight agent on your computer that executes tool calls

3. Secure Connection: Token-based pairing with configurable approval for destructive operations

Related MCP server: ArenaBridge

Quick Start

1. Install the Runner

curl -fsSL https://pcbridge.vercel.app/setup.sh -o setup.sh && bash setup.sh

2. Get a Pairing Code

Go to pcbridge.vercel.app/dashboard and click "Generate Code".

3. Start PCBridge

pcbridge start --code XXXXXX

4. Configure Your Chatbot

Add to your chatbot's MCP configuration:

{
  "mcpServers": {
    "pcbridge": {
      "url": "https://pcbridge.vercel.app/api/mcp",
      "headers": {
        "X-Device-Id": "YOUR_DEVICE_ID"
      }
    }
  }
}

Features

• File Operations: Read, write, edit, list, and delete files

• Terminal: Execute commands with configurable approval for destructive operations

• Git: Status, diff, log, and commit (with approval)

• Secure: Token-based pairing, path sandboxing, approval system

• MCP Native: Works with any MCP-compatible chatbot

• Cross-Platform: Linux (including Omarchy), macOS, Windows (WSL2)

Architecture

Security

• All execution stays on your computer

• Token-based device pairing

• Path sandboxing (operations restricted to project directory)

• Configurable approval for destructive operations

• Encrypted cloud communication

Development

# Install dependencies
npm install

# Run locally
npm run dev

# Build
npm run build

# Type check
npm run typecheck

Deployment

The cloud gateway keeps runtime state (paired devices, pending approvals) in a store. On serverless hosts each request can hit a different instance, so state must be shared:

1. Deploy to Vercel.

2. Add an Upstash Redis database (Vercel → Storage → Upstash, or the Marketplace integration). This injects KV_REST_API_URL and KV_REST_API_TOKEN automatically.

3. Redeploy. /api/health reports "storage": "shared".

Without a shared store, the app falls back to in-memory state — fine for local development and single-instance hosting, but on Vercel the dashboard may not show a connected runner. The dashboard warns when in-memory mode is active.
