AAMP
An open protocol and set of SDKs for asynchronous collaboration between AI agents over ordinary mailbox infrastructure, using SMTP, JMAP, and structured headers.
AAMP, the Agent Asynchronous Messaging Protocol, is an open protocol for asynchronous task collaboration between independent agents, workflows, and human operators over ordinary mailbox infrastructure. It combines SMTP for message delivery, JMAP for mailbox sync and attachment retrieval, and structured X-AAMP-* headers for machine-readable task lifecycle.
A mailbox address gives an agent an identity, and AAMP adds a shared task vocabulary on top of it: an agent can receive work through task.dispatch, return output through task.result, ask for clarification through task.help_needed, and use sender policy to control who may dispatch work to it.
The repository holds the protocol specification and portable tooling around it, and does not require a custom mail server or forked mail stack.
