Solo Desktop Commander MCP

A completely free, open-source Desktop Commander MCP for solo developers and vibe coders. Give any MCP-compatible AI agent real filesystem, terminal, git, and process control over your own machine — inspect, diagnose, repair, and verify, all from chat. No accounts. No cloud. No telemetry. No login.

This package contains the web application that showcases the project: a polished, interactive landing page with real WebGL 3D motion graphics plus a working MCP-style server that genuinely inspects a live project.

Highlights

• Interactive 3D hero — a WebGL scene (Three.js / React Three Fiber) with a rotating wireframe "commander core", 22 orbiting module nodes, a 900-point particle field, and mouse-driven camera parallax. Respects prefers-reduced-motion.

• 3D tilt module cards — every module card tilts toward the pointer with layered translateZ depth and a glow border on hover.

• Cohesive motion — staggered hero entrance, scroll-triggered reveals, and a floating 3D architecture centerpiece (Framer Motion).

• Working MCP server — POST /api/commander exposes real tools that inspect the project.

• Security layer — path confinement + command allowlist (e.g. rm -rf / is refused).

The interactive MCP server

POST /api/commander is a real, working MCP-style tool server:

Security model (built-in, on by default)

• Path confinement — filesystem tools cannot escape the project root.

• Command allowlist — run_command only executes known-safe commands; everything else (e.g. rm -rf /) is refused with a clear message.

• Structured errors — every failure returns { ok: false, output }, never a 500.

• Every call is logged & timestamped in the on-screen activity log.

Run it locally

Requires Node 18+ and Bun (recommended) or npm/pnpm.

# 1. install dependencies (includes three, @react-three/fiber, @react-three/drei)
bun install        # or: npm install / pnpm install

# 2. configure the database url
cp .env.example .env

# 3. (optional) push the prisma schema
bun run db:push

# 4. start the dev server
bun run dev        # or: npm run dev

Then open http://localhost:3000.

The homepage is the only user-facing route (src/app/page.tsx). The MCP tool endpoint lives at /api/commander.

Tech stack

• Next.js 16 (App Router) + TypeScript 5

• Tailwind CSS 4 + shadcn/ui (New York)

• Three.js + @react-three/fiber + @react-three/drei — WebGL 3D hero scene

• Framer Motion — entrance, tilt, scroll-reveal, floating animations

• Prisma ORM (SQLite)

• lucide-react icons, sonner toasts

• Forced dark "terminal" theme with emerald/amber accents
