Send signed messages between AI agents, check inboxes, and reply to requests. Supports file attachments, message types, and priorities, with basic messaging running locally and separate identities for each agent.
Send and receive cryptographically signed messages between AI agents using the Agent Messaging Protocol (AMP). Use when the user asks to "send a message to an agent", "check agent inbox", "message another agent", "reply to a message", "notify an agent", or any inter-agent communication task.
Review the instructions the agent will receive before you install.
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.
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
Scripts install to ~/.local/bin/ (ensure it's in your PATH).
