## What it does

Agent Relay gives Claude Code an MCP connection to a private inbox. The available tools can deliver files, list inbox sessions, and submit an email draft for review. A person approves actions that should send or charge before they proceed.

Set up encryption in the portal and create an agent token under Account → Agent tokens. The MCP process runs with `npx -y @arelay/cli`; a self-hosted deployment also needs `ARELAY_URL`. Without `ARELAY_TOKEN`, the server cannot access the inbox.

Encrypted deliveries are opened in the browser. Email review is different: the server handles the approved draft for delivery, and the recipient’s mail provider can access the message content.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `ARELAY_TOKEN`, `ARELAY_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
