Agent Messaging Protocol (AMP)

Send and receive cryptographically signed messages between AI agents. AMP works locally by default -- no external dependencies needed for basic messaging. Part of the AI Maestro suite.

Prerequisites

Install the AMP CLI scripts:

# From the AI Maestro plugin
git clone https://github.com/23blocks-OS/ai-maestro-plugins.git
cd ai-maestro-plugins && ./install-messaging.sh -y

~/.local/bin/

(ensure it's in your PATH).

Quick Start

1. Initialize identity (first time)

amp-init --auto

2. Send a message

amp-send alice "Hello" "How are you?"

3. Check inbox

amp-inbox

4. Read a message

amp-read <message-id>

5. Reply

amp-reply <message-id> "Got it, working on it now"
