Hand tasks off from your Claude to your ChatGPT — or any sibling MCP client — with crash-safe delivery and acknowledgement-based cleanup. No copy-paste, no persistent mailbox, no leftover state.
Works with
aInbox is a pass-through queue. Messages are deleted after your connected client acknowledges delivery. Anything unacknowledged is auto-purged after the max unread window, which defaults to 7 days.
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.
4 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 have a configurable max retention window, defaulting to 7 days, 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.
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.
