## What it is
Go Micro is a Go framework and CLI that combines an AI agent harness with a microservices framework, giving agents tools, memory, guardrails, planning, and service discovery on one runtime. Service endpoints automatically become AI-callable tools via MCP, agents are reachable over the A2A protocol, and deterministic work is orchestrated with durable, checkpointed flows.

## Use cases
- build AI agents in Go with tools and memory
- expose microservice endpoints as MCP tools for LLMs
- generate services from a natural language prompt
- orchestrate multi-agent workflows with durable flows
- make agents discoverable via the A2A protocol
- scaffold and hot-reload microservices locally with a CLI
- build a chatbot that talks to backend services

## When to choose
- you're building agents or agent-backed services in Go
- you want MCP/A2A interoperability out of the box
- you need a batteries-included microservices runtime with pluggable discovery, RPC, and pub/sub
- you want deterministic workflows that hand off to LLM agents

## When to avoid
- you need a lightweight agent library without a full service framework
- your stack is Python or TypeScript rather than Go
- you want a minimal HTTP framework without AI/agent features
- you need a very mature, conservative framework — the agent features are new and evolving
