# Hermes by Sundartha: give your AI a phone number

> Hermes answers calls and handles them for you. One connection over MCP, and your AI gets a voice.

This is the Markdown version of https://sundartha.com/ for AI agents. The page itself switches between English and German.

## How it works

One connection over MCP, no setup. Your AI is reachable on a real number in under two minutes.

1. **Get a number.** A real phone number. Active in two minutes. No contract, no hardware.
2. **Connect your AI.** One connection over MCP. Claude, Codex or any MCP client. Your AI knows who called.
3. **Let it answer.** Talks and listens. Books appointments. Your 24/7 personal assistant.

## Pricing

Two plans, no surprises. Cancel monthly, no hidden costs.

| Plan | Price | Included | What you get |
