Varity MCP Server

Deploy any Node or Python app, AI agent, or LLM straight from your AI coding tool — one command, live in 60 seconds.

@varity-labs/mcp is the Model Context Protocol server for Varity. It gives AI coding tools — Claude Code, Cursor, Codex, Windsurf — the tools to scaffold, build, and deploy your app for you. Ask your editor to ship your project and it goes from local code to a live URL, with the database and backend services it needs wired automatically.

Varity is a fixed monthly cost per app, 60-80% cheaper than Vercel, Render, or Railway — your bill does not change with traffic.

Install

Add the server to your AI tool's MCP config:

{
  "mcpServers": {
    "varity": {
      "command": "npx",
      "args": ["-y", "@varity-labs/mcp@beta"]
    }
  }
}

• Claude Code: claude mcp add varity -- npx -y @varity-labs/mcp@beta
• Cursor / Windsurf / Codex: add the JSON above to your MCP settings.

Then ask your editor: "Deploy this app with Varity."

What you can do

Once connected, your AI tool can:

• Deploy your code — varitykit app deploy equivalent, one step, returns a live URL
• Estimate cost before you ship, with the built-in calculator
• Migrate from Vercel in seconds
• Deploy curated AI agent templates with one command
• Scaffold, build, and run projects locally
