* test(harness): read agent plan from the scoped store
The store-scoping change moved an agent's plan from the default table
key agent/{name}/plan to its own table (database "agent", table {name},
key "plan"). The plan-delegate harness tests still read the old key and
failed with 'not found'; read through store.Scope(mem, "agent", name)
like the agent does.
* docs: orient agents-first across README, landing, and docs overview
Lead with agents (then services and flows), surface MCP + A2A as the
interop story, and frame agents as services. Landing hero and feature
grid reordered agents-first with an A2A gateway card.
* v6: module path go-micro.dev/v6, TLS secure by default, NewService
Cut v6. Three breaking changes, bundled so the major bump is paid once:
- Module path go-micro.dev/v5 -> go-micro.dev/v6 across all imports + go.mod.
- TLS verification on by default (was off). MICRO_TLS_SECURE removed;
MICRO_TLS_INSECURE=true opts out for self-signed/dev.
- micro.NewService(name, opts...) is the canonical service constructor,
symmetric with NewAgent/NewFlow; micro.New kept as a deprecated alias;
the old name-less NewService(opts...) removed. Generators emit NewService.
Also ports the JWT auth token provider in-module (go-micro.dev/v6/auth/jwt/token
on golang-jwt/jwt/v5), dropping the v5-pinned github.com/micro/plugins/v5/auth/jwt
and the deprecated dgrijalva/jwt-go.
Docs/README/landing updated to v6 and @latest; v5->v6 migration guide added;
CHANGELOG cut as [6.0.0]. Blog posts left at their historical versions.

MCP Hello World Example
The simplest possible MCP-enabled go-micro service.
What This Shows
- ✅ Automatic documentation extraction from Go comments
- ✅ MCP gateway setup with 3 lines of code
- ✅ Ready for Claude Code integration
- ✅ HTTP endpoint for testing
Run It
cd examples/mcp/hello
go run main.go
Test It
Option 1: HTTP API
# List available tools
curl http://localhost:3000/mcp/tools | jq
# Call the SayHello tool
curl -X POST http://localhost:3000/mcp/call \
-H "Content-Type: application/json" \
-d '{
"tool": "greeter.Greeter.SayHello",
"input": {"name": "Alice"}
}' | jq
Option 2: Claude Code
In a separate terminal:
micro mcp serve
Add to ~/.claude/claude_desktop_config.json:
{
"mcpServers": {
"greeter": {
"command": "micro",
"args": ["mcp", "serve"]
}
}
}
Restart Claude Code and ask:
"Say hello to Bob using the greeter service"
How It Works
1. Write Normal Go Code
// SayHello greets a person by name. Returns a friendly greeting message.
//
// @example {"name": "Alice"}
func (g *Greeter) SayHello(ctx context.Context, req *HelloRequest, rsp *HelloResponse) error {
rsp.Message = "Hello " + req.Name + "!"
return nil
}
2. Register the Handler
// Documentation is extracted automatically!
handler := service.Server().NewHandler(new(Greeter))
service.Server().Handle(handler)
3. Start MCP Gateway
go mcp.ListenAndServe(":3000", mcp.Options{
Registry: service.Options().Registry,
})
That's it! Your service is now AI-accessible.
What Gets Extracted
From this code:
// SayHello greets a person by name. Returns a friendly greeting message.
//
// @example {"name": "Alice"}
func (g *Greeter) SayHello(...)
type HelloRequest struct {
Name string `json:"name" description:"Person's name to greet"`
}
Claude sees:
{
"name": "greeter.Greeter.SayHello",
"description": "SayHello greets a person by name. Returns a friendly greeting message.",
"inputSchema": {
"type": "object",
"properties": {
"name": {
"type": "string",
"description": "Person's name to greet"
}
},
"examples": ["{\"name\": \"Alice\"}"]
}
}
