- 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

* 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.

Implement Q2 2026 roadmap items for AI-native microservices:
MCP stdio transport:
- JSON-RPC 2.0 over stdio for Claude Code integration
- Methods: initialize, tools/list, tools/call
- Auto-detection: stdio (no address) vs HTTP/SSE (with address)
micro mcp command:
- 'micro mcp serve' - start MCP server (stdio or HTTP)
- 'micro mcp list' - list available tools
- 'micro mcp test' - test a tool (placeholder)
- Enables Claude Code users to add microservices as tools
Gateway refactor:
- Created gateway/api package (reusable, 150 lines)
- Moved gateway logic from cmd/micro/server/gateway.go
- HandlerRegistrar pattern for flexibility
- cmd/micro/server/gateway.go now compatibility wrapper (72 lines)
- 50% code reduction, better separation of concerns
- Library users can now use gateway in custom apps
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Major Features:
- Unified gateway architecture (micro run + micro server use same code)
- MCP (Model Context Protocol) integration as library package
- AI-accessible microservices with 3 lines of code
Gateway Unification:
- Created reusable gateway module (cmd/micro/server/gateway.go)
- Updated micro run to use unified gateway (removed duplicate code)
- Conditional authentication (disabled in dev, required in prod)
- Reduced code duplication, simplified maintenance
MCP Integration:
- New library package: gateway/mcp
- Automatic service discovery → MCP tools
- HTTP/SSE transport support (stdio coming soon)
- Works for both library users and CLI users
- CLI flags: --mcp-address for micro run and micro server
Documentation:
- ADR-010: Unified Gateway Architecture
- CLI & Gateway Guide for users
- MCP Gateway README and examples
- Blog post: Making Your Microservices AI-Native with MCP
Breaking Changes: None (fully backward compatible)

* Initial plan
* Fix insecure TLS configuration - make secure by default
- Changed util/tls/Config() to be secure by default (InsecureSkipVerify=false)
- Added MICRO_TLS_INSECURE=true environment variable for development/testing
- Updated documentation to emphasize security-first approach
- Added comprehensive tests for TLS configuration
- All existing broker tests pass
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Revert to backward-compatible TLS defaults to avoid breaking changes
- Reverted default to InsecureSkipVerify=true for backward compatibility
- Changed environment variable to MICRO_TLS_SECURE=true (opt-in security)
- Added deprecation warning that logs once per process
- Updated tests to reflect backward-compatible behavior
- Added comprehensive migration guide
- No breaking changes - production systems safe to upgrade
- Security improvement is opt-in via environment variable
- Planned breaking change for v6 with proper major version bump

* Add TLS security update documentation

* Initial plan
* Apply rate limiting before singleflight to prevent blocking
- Check rate limiting BEFORE entering singleflight
- If rate-limited AND stale cache exists, return stale cache immediately
- This prevents all goroutines from blocking when etcd is down/slow
- Maintains stampede prevention via singleflight for non-rate-limited requests
- All existing tests pass
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Fix variable shadowing in rate limiting check
- Rename shadowed variables to currentLastRefresh and currentMinimumRetryInterval
- Improves code clarity and prevents potential bugs
- All tests still pass

- /blog/ - Blog index page
- /blog/1 - First post announcing micro deploy
- /docs/deployment.md - Deployment guide in website docs
- Updated navigation to include Blog link
- New blog layout template

* Add systemd-based deployment support
- micro init --server: Initialize server to receive deployments
- Creates /opt/micro/{bin,data,config} directories
- Generates systemd template unit (micro@.service)
- Creates 'micro' system user
- micro deploy: Deploy services via SSH + systemd
- Builds linux/amd64 binaries automatically
- Copies via rsync/scp to server
- Manages services via systemctl
- Helpful error messages for common issues
- micro status --remote: Check remote service status
- micro logs --remote: Stream remote logs via journalctl
- micro stop --remote: Stop services on remote server
- Config: Added 'deploy' blocks to micro.mu for named targets
The deployment model:
- systemd is the process supervisor (battle-tested)
- SSH is the transport (standard, secure)
- No custom daemons or platforms needed

micro build:
- Default: builds Go binaries to ./bin/
- Cross-compile with --os and --arch
- Docker is optional via --docker flag
micro deploy:
- Requires --ssh user@host
- Copies pre-built binaries (if ./bin/ exists)
- Or syncs source and builds on remote
- No Docker dependency
Go binaries are self-contained. No runtime needed.

Provides a test harness for running micro services in isolation:
h := testing.NewHarness(t)
defer h.Stop()
h.Name("users").Register(new(UsersHandler))
h.Start()
var rsp Response
h.Call("UsersHandler.Create", &req, &rsp)
Features:
- Isolated registry, transport, and broker per harness
- Simple API: Name(), Register(), Start(), Stop()
- Call helpers: Call(), CallContext()
- Assertions: AssertServiceRunning(), AssertCallSucceeds(), AssertCallFails()
- Access to underlying Client(), Server(), Registry()
Note: Due to go-micro's global defaults, each harness tests one service.
For multi-service testing, use integration tests or mocks.
Also fixes README.md example showing conflicting port 8080.

micro run now starts an HTTP gateway alongside your services:
- Web dashboard at http://localhost:8080
- API proxy at /api/{service}/{method}
- Health checks at /health
- Service listing at /services
The experience is now:
$ micro new helloworld
$ cd helloworld
$ micro run
Open http://localhost:8080 to see and call your services.
New flags:
--address :3000 # Custom gateway port
--no-gateway # Disable gateway (services only)
Updated documentation to make this the central experience.

Adds a new health package providing:
- /health endpoint for overall health status
- /health/live for Kubernetes liveness probes
- /health/ready for Kubernetes readiness probes
- Built-in checks: PingCheck, TCPCheck, HTTPCheck, DNSCheck
- Critical vs non-critical checks
- Concurrent check execution
- Configurable timeouts
- Service info metadata
Integrates with micro run's health check waiting when services
specify a port in their micro.mu configuration.
Example usage:
health.Register("database", health.PingCheck(db.Ping))
health.Register("redis", health.TCPCheck("localhost:6379", time.Second))
health.RegisterHandlers(mux)
