@replyz/cli

An email inbox for your AI agent, from the command line. The agent signs itself up, gets its own address on youreplyz.com, and waits for verification codes and links. It receives mail; the only mail it can send is a short note to your own human (tell-human).

Status: early access (0.2.0). Whether signups are open right now is shown on https://replyz.io; while they are closed, signup answers signups_disabled.

npx -y @replyz/cli@0.2.0 signup --name scout --json      # once: account + inbox, key saved for you
npx -y @replyz/cli@0.2.0 wait --otp --from "*@service.com" --json

Node.js 22 or newer. No runtime dependencies.

Commands

Command	What it does
signup --name <name> [--force] [--print-key]	Creates a sandbox account (7 days) with one inbox. Solves a small proof of work. Saves the API key to ~/.config/replyz/credentials.json (mode 0600); --print-key also prints it. Refuses if this machine already has an account, unless --force
status	Account status, expiry, limits and usage
inbox ls / inbox create [--name] [--display-name]	List or create inboxes
messages ls [--inbox] [--unread] [--from] [--since] [--limit]	Recent messages, newest first
read <message_id> [--html]	One message in full
wait [--inbox] [--from] [--subject] [--since] [--timeout 0-600] [--otp] [--link] [--new]	Waits for mail. Mail from the last 10 minutes counts. --otp/--link return the code and/or verification link
tell-human [--inbox] --subject <s> <text>	Emails the human who claimed this account (only them; at most 10 a day; queued, not delivered): POST /v1/inboxes/{id}/email-human. Until Replyz switches sending on, or for an unclaimed account, it answers sender_unavailable / not_claimed: tell your human in your own chat. Errors carry fix and, when the API sends a Retry-After, retry_after_s
mcp install [--client claude-code|cursor|print]	Adds the Replyz remote MCP server (https://mcp.replyz.io/mcp, live; needs an API key) to an MCP client (default: prints the config)

Every command takes --json: one JSON document on stdout, errors as {"error": {"code", "status", "message", "fix"}}. Exit codes: 0 ok, 1 error, 2 usage, 3 wait timed out.

Environment: REPLYZ_API_KEY (overrides the saved key), REPLYZ_API (API address, default https://api.replyz.io), REPLYZ_MCP_URL, REPLYZ_CONFIG_DIR.
