Agent Inbox
Agent Inbox, from the open-source notification company Novu, gives an AI agent its own email address plus Slack and Telegram handles in one shared inbox, with a CLI and MCP server to send messages, reply, and ask people for approvals or choices.
Why it matters
For anyone running an AI agent that needs to reach real people, whether that's asking a teammate for approval, following up with a customer, or receiving one-time sign-up codes. It keeps email, Slack and Telegram conversations in one thread the agent can read.
Highlights
- One inbox per agent with an email address, plus optional Telegram and Slack connections that all share it; WhatsApp and iMessage are listed as coming soon.
- CLI commands (agentinbox setup, send, reply, list, contact invite) and a hosted MCP server, with guides for Claude Code, Codex, Cursor, OpenCode and others.
- Structured requests: start a message with ask, approve or choose to get a structured answer back, with --ttl deadlines (default 24h, max 5 days) and an --async mode.
- Contacts model: the agent writes to people you invite, and an email to a new address on a new conversation adds them as a contact.
- Runs on Novu's infrastructure, which the page says is SOC 2 Type II and ISO 27001 certified; enterprise options include sending from your own domain.unverified

Worth knowing: An agent with its own address can email people on your behalf, so limit who it can contact and review what it sends. The homepage is written for agents to follow as setup instructions.
