What is it?

Go Micro is a Go framework for building distributed systems. It provides the building blocks most microservice setups need: RPC with streaming, message encoding, service discovery, messaging, storage, and configuration. Each component is defined as a Go interface with a default implementation, so the parts can be swapped out.

The framework also includes an agent layer. Agents can use services as tools, keep conversation history, and run through configured models. Workflows coordinate ordered steps with retries and checkpoints, mixing service calls and agent tasks.

A gateway exposes services over HTTP and MCP, so other applications and AI agents can call them. Developers can start with plain Go services and RPC without using any model, or add the agent and gateway pieces as needed.

Key features

  • 01RPC with streaming and message encoding
  • 02Service discovery and messaging
  • 03Storage and configuration components behind Go interfaces
  • 04Agents that use services as tools and keep conversation history
  • 05Workflows with ordered steps, retries and checkpoints
  • 06Gateway exposing services over HTTP and MCP

Use cases

  • Building microservices in Go that need RPC and service discovery
  • Exposing internal Go services to AI agents through MCP
  • Orchestrating multi-step tasks that combine service calls and agent work

Quick start

  1. 1

    Install the framework with Go

    go get go-micro.dev/v6@latest
  2. 2
