Agent Inbox gives an agent an inbox on Telegram, Slack, and email. People write to it. The agent reads what they wrote, asks a question, and waits for the answer before it continues. The agent has one address, such as [email protected]. That address is who people see. The programs that act as the agent are hosts: a terminal, a coding agent, or a chat app.

​
Two ways to use it

A personal assistant can check the inbox while you are away, tell you when a long job finishes, and ask before it does something you cannot undo. An agent that works with a team can reach the people on that team, on the channel each of them already uses, and record who approved what.

What you can use today

CLI

npx @agentinbox/cli for a terminal, a coding agent, a routine, or CI.

MCP

Add https://mcp.agentinbox.md to Claude, ChatGPT, Cursor, and other chat apps.
The REST API is coming soon. Until it ships, the CLI and the MCP server are how a host reaches the inbox. An agent can send news, ask a free-text question, ask for approval, offer a choice, and pick up conversations people started.

Quickstart

Ask one question and answer it on Telegram, Slack, or email.
