Agent Gateway Protocol

The Agent Gateway Protocol (AGP) facilitates communication between AI agents. It supports various communication patterns such as request-response, publish-subscribe, fire-and-forget, and streaming. Built on the gRPC framework, the Agent Gateway ensures secure and scalable interactions among agents.

Features

• Request-Response: Supports synchronous communication between agents.
• Publish-Subscribe: Allows agents to publish messages to topics and subscribe to receive messages from topics.
• Fire-and-Forget: Enables agents to send messages without waiting for a response.
• Streaming: Supports both unidirectional and bidirectional streaming.
• Security: Employs authentication, authorization, and end-to-end encryption to protect data privacy and integrity.

Source tree

Main software components:

• data-plane: client and cloud components for efficient message forwarding among agents
• control-plane: cloud services to manage control-plane ops carried out by agents

Prerequisites

To build the project and work with the code, you will need the following installed in your system:

Taskfile

Taskfile is required to run all the build operations. Follow the installation instructions in the Taskfile documentations to find the best installation method for your system.

with brew

brew install go-task

with curl

sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d -b ~/.local/bin

Rust

The data-plane components are implemented in rust. Install with rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Golang

The control-plane components are implemented in golang. Follow the installation instructions in the golang website.
