Vox runs locally on your hardware. Your conversations, files, and data never leave your device. No cloud, no telemetry.

What can Vox do that ChatGPT cannot?

Vox controls your desktop — it manages files, sends emails, replies to iMessages, captures screen regions, and runs background agents. It works offline and keeps all data on your device.

Does Vox work on Windows or Linux?

Vox is Mac-first today. The core architecture is platform-agnostic, and Windows and Linux support is the top contributor priority.

How to Connect an MCP Server to Vox

Vox has a built-in MCP panel that lets you connect any MCP-compatible server in seconds. Once connected, Vox automatically discovers the server's tools and makes them available to the agent — no extra configuration needed.

Step 1: Open the Tools panel

Click the wrench icon in the left sidebar to open the Tools panel, then switch to the MCP Servers tab.

Step 2: Connect your server

Click Connect. A drawer slides in asking for three things:

Display Name

A name for this server

Something you'll recognise — "Figma", "My Postgres DB", "GitHub".

Transport

How Vox talks to the server

stdio for local processes (run with a command like "npx figma-mcp"), SSE or HTTP for remote servers with a URL.

Auth Token

Optional authentication

If the server requires a bearer token, paste it here. It's encrypted and never exposed.

Step 3: Sync tools

After connecting, hit Sync. Vox connects to the server, discovers all its tools, and imports them into your tool library with embeddings generated automatically. This makes them searchable by the agent.

Tip

Popular MCP servers you can connect right now:
• npx -y @modelcontextprotocol/server-github
• npx -y figma-developer-mcp
• npx -y @modelcontextprotocol/server-postgres
• npx -y @modelcontextprotocol/server-brave-search

Step 4: Use your tools

That's it. Just describe what you want in natural language. Vox will find the right tool from your library and call it.

Note

MCP tools sync on demand. If the server adds new tools, just hit Sync again to pull them in.

What Is MCP? The Protocol That Lets AI Use Any Tool

MCP (Model Context Protocol) is the open standard that lets AI assistants connect to external tools and data sources. Here's what it is, why it matters, and how Vox uses it.

Guides

Creating Custom Tools for Vox

Build your own tools for Vox — JS functions, webhooks, or desktop actions. Add secrets, write code, and let the agent discover and call your tool automatically.
