* Initial plan
* Add MCP per-tool scopes, tracing, rate limiting, and audit logging
- Add Scopes field to Tool struct for per-tool scope requirements
- Add Auth (auth.Auth) integration to Options for token inspection
- Add trace ID generation (UUID) propagated via metadata to downstream RPCs
- Add per-tool rate limiting with configurable requests/sec and burst
- Add AuditFunc callback for immutable tool-call audit records
- Extract tool scopes from registry endpoint metadata ("scopes" key)
- Update both HTTP and stdio transports with auth/trace/rate/audit
- Add comprehensive tests for all new functionality

* Revert unrelated example go.mod changes
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Remove auto-generated example go.sum files
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Add WithEndpointScopes helper, gateway-level ToolScopes, and documentation
- Add server.WithEndpointScopes() for declaring per-endpoint auth scopes at
handler registration time
- Add mcp.Options.ToolScopes for gateway-level scope overrides without
changing individual services
- Update documented example to show WithEndpointScopes usage
- Update examples/mcp/README.md with scopes, tracing, and rate-limiting docs
- Update gateway/mcp/DOCUMENTATION.md with scopes section and FAQ
- Add tests for both new features

* Fix ToolScopes doc comment: clarify override (not merge) semantics
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Revert unrelated example go.mod/go.sum changes
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Rename ToolScopes to Scopes in MCP Options
The field name "Scopes" is more universal and consistent with how
auth scopes are used throughout go-micro. Updated all code references,
tests, and documentation.

Go Micro Examples
This directory contains runnable examples demonstrating various go-micro features and patterns.
Quick Start
Each example can be run with go run . from its directory.
Examples
hello-world
Basic RPC service demonstrating core concepts:
- Service creation and registration
- Handler implementation
- Client calls
- Health checks
Run it:
cd hello-world
go run .
web-service
HTTP web service with service discovery:
- HTTP handlers
- Service registration
- Health checks
- JSON REST API
Run it:
cd web-service
go run .
Coming Soon
The following examples are planned:
- pubsub-events - Event-driven architecture with NATS
- grpc-integration - Using go-micro with gRPC
- production-ready - Complete production-grade service with observability
Prerequisites
Some examples require external dependencies:
- NATS:
docker run -p 4222:4222 nats:latest - Consul:
docker run -p 8500:8500 consul:latest agent -dev -ui -client=0.0.0.0 - Redis:
docker run -p 6379:6379 redis:latest
Contributing
To add a new example:
- Create a new directory
- Add a descriptive README.md
- Include working code with comments
- Add to this index
- Ensure it runs with
go run .
