aInbox gives ChatGPT, Claude or any MCP assistant its own @ainbox.io address. People email it, attachments included, and your assistant reads, summarizes and replies when you ask.
For example
Forward a customer email → ChatGPT drafts the reply.
It mirrors your tone and waits for your sign-off before sending.
Works with
Email, webhooks, schedules, sibling agents — they all converge into one address. Your Claude, ChatGPT, or any MCP client pulls context from the same place. One bus, every channel, both directions.
Add aInbox as an MCP integration in Claude, ChatGPT, or any MCP client.
Enter your email and a one-time verification code. Your account and agent addresses are created automatically.
Your agents pass context to each other async. Delivered messages are deleted after acknowledgement; unacknowledged messages can reappear safely.
Focused MCP tools. Crash-safe delivery, presence-aware discovery, ephemeral by design.
Hand a task off from your Claude to your ChatGPT — or any sibling MCP client — with send_message. Async, durable, no copy-paste.
Read with pull_messages, confirm with ack_messages. If your agent crashes before the ack, the message reappears on the next pull. No lost work, no hand-rolled retry logic.
Delivered messages are deleted on acknowledgement. Unread messages are kept for at least 31 days, then expire, so queues cannot accumulate forever.
Humans can email your agent at you@ainbox.io. Their messages land in the same queue and obey the same crash-safe delivery and max-unread retention rules.
Each sibling gets its own sub-address. Call list_agents at session start to learn your own address, who your siblings are, and which ones are currently listening for replies.
We can't train on messages we don't keep. aInbox is a relay, not a mailbox: your data passes through, then it's gone. Your data, your control. Delete your account anytime.
aInbox gives your AI assistant its own email address. You get an @ainbox.io address; anything emailed to it, attachments included, waits there until your assistant reads it, summarizes it and, if you ask, replies.
ChatGPT, Claude (claude.ai, Claude Desktop and Claude Code), WorkBuddy, OpenClaw, and any other client that can add a remote MCP server over Streamable HTTP with OAuth. Assistants you connect with the same sign-in share one inbox.
Add the connection URL mcp.ainbox.io as a custom connector (remote MCP server) in your assistant and sign in. Your @ainbox.io address is created on first sign-in. Step-by-step guides: ainbox.io/setup/chatgpt and ainbox.io/setup/claude.
Read messages and the text of PDF, Word, Excel and OFD attachments, fetch attachment originals, reply, or send new email within per-account limits (by default 20 per hour and 100 per day). Your assistant checks the inbox when you ask; aInbox does not start it on its own.
Message content is deleted as soon as your assistant confirms it has read it. Unread messages are kept for at least 31 days, then expire. You can delete messages or your whole account in account settings at any time.
Yes. aInbox is free to use; there is nothing to install. Sign in with Google, an email code or WeChat.
Pass context between your AI agents with acknowledgement-based cleanup and configurable max-unread retention. Works with Claude, ChatGPT, Claude Code, and any MCP platform.
