# Outbound Messenger Protocol • AI Agent SDK

> OutboundMessengerProtocol: Protocol for agent-facing proactive message delivery.

# OutboundMessengerProtocol

> Defined in the [**protocols**](https://praison.ai/docs/sdk/reference/praisonaiagents/modules/protocols.md) module.

AI Agent

Protocol for agent-facing proactive message delivery.

A concrete implementation is provided by the running gateway/bot (in the
praisonai wrapper) and registered into the per-turn context so the
built-in `send_message` tool can resolve it. It bridges to the existing
delivery stack (DeliveryRouter, HomeChannelRegistry, outbox, mirroring).

Example usage (implementation in praisonai\_bot.gateway)::

messenger = BotOutboundMessenger(bot, resolver, router)
token = register\_outbound\_messenger(messenger)
try:
...  # agent runs; send\_message tool resolves the messenger
finally:
clear\_outbound\_messenger(token)
