Deploy production apps and AI agents from Cursor, Claude Code, VS Code, Windsurf, or ChatGPT. Flat predictable pricing — your bill stays the same as your app grows.

The Varity MCP Server lets your AI editor build, deploy, and manage apps in production for you. Flat monthly cost per app, locked at deploy time based on hardware reserved — no usage-based billing, no surprise overages. One server, every AI client, zero commands.

Browser usage: see the browser usage guide for Claude.ai or ChatGPT browser. Quick start: pick your editor below and run one command.

What you can do from your AI editor

The MCP exposes Varity's deploy surface so your AI tool can take action — not just generate code. Try prompts like:

Deploy your own code

• "Deploy this project to production"
• "Ship this app live"
• "What would it cost to deploy this on Varity?"

Deploy a ready-made AI agent (one command, no code required)

• "Deploy a Telegram chatbot for me"
• "Spin up Agent Zero"
• "I want a Claude-compatible chat UI"
• "What AI agents can Varity deploy?"

Manage live deployments

• "Show my deployments"
• "What's the URL of my last deploy?"
• "Stop my-app and stop billing it"
• "Get the build logs for my deployment"

Migrate from Vercel

• "Migrate my Vercel app at github.com/me/my-app to Varity"
• "Preview what changes the migration will make"

Docs and pricing

• "Search Varity docs for environment variables"
• "How much would it cost to host a 5,000-user API on Varity?"
• "What's my monthly cost going to be if my app gets traction?"

AI agent templates

Varity ships 5 curated AI agent templates that deploy with one command and no code from you:

| Agent | What it is | |---|---| | hermes | Self-hosted Telegram chatbot powered by an LLM | | openclaw | Claude-compatible web chat UI with persistent history | | agent-zero | General-purpose AI agent framework — zero required env vars | | autoresearch | GPU-backed CUDA workstation (SSH access) | | eliza-venice | ElizaOS agent for Twitter/X automation |

Ask your AI editor "what AI agents can I deploy?" or "deploy hermes for me" and it will use the agent tools above. Each agent reserves different hardware — use varity_agent_info <name> to see current monthly cost. Each agent also has a small set of required environment variables (e.g. a Telegram bot token, an API key) that the AI editor will prompt you for.

End-to-end example

From empty folder to deployed app, all in natural language:

You: "Make me a simple landing page for my coffee shop and deploy it"
AI:  Wrote the landing page, ran the build, deployed live at
     https://varity.app/coffee-shop/

You: "Now deploy a Telegram bot I can chat with"
AI:  Need three things: an OpenAI API key, a Telegram bot token (get
     one from @BotFather), and your Telegram user ID.
You: (provides them)
AI:  Deployed hermes agent at https://varity.app/my-bot/
     Send a message to your bot on Telegram to chat with it.

How Varity is priced

• Flat monthly cost per app: locked at deploy time, based on the hardware your app reserves. Your bill on day 1 equals your bill on day 1000.
• No usage-based billing: cost doesn't change with traffic, requests, bandwidth, or build minutes. No surprise overages.
• No plan tiers: every feature is in every account; you don't pay for "Pro" to unlock anything.

Ask your AI editor "how much would this app cost on Varity?" and it will use varity_cost_calculator to estimate before you deploy.
