- Create docs/releasing.md with hotfix/x.y.z workflow - Add PR template with hotfix backport reminders - Document GitHub environments setup for production/staging - Establish next branch for development aggregation This implements the P0 branching model to keep main hotfixable while aggregating refactor work in next branch.
This document outlines the complete refactoring strategy from core+tray split through v1 REST API, embedded Web UI, hardened OAuth/storage, and robust tests/observability while preserving hotfix/release workflow.
- Update release.yml for stable releases from main with production environment - Add prerelease.yml for next branch with staging environment - Prerelease workflow excludes latest assets to prevent auto-updates - Environment separation for production vs staging secrets - Both workflows include codesigning and notarization - Only stable releases update Homebrew tap Implements P1 from refactoring plan for proper release management.
- Add MCPPROXY_ALLOW_PRERELEASE_UPDATES environment flag (default: false) - Modify getLatestRelease to respect prerelease flag - Add getLatestReleaseIncludingPrereleases for canary behavior - Update GitHubRelease struct to include Prerelease field - Comprehensive unit tests for asset selection logic - Update AUTOUPDATE.md with prerelease/canary mode documentation Safety features: - Prerelease workflow excludes latest assets (prevents auto-update) - Default behavior only updates to stable releases - Opt-in flag required for prerelease updates - All existing functionality preserved Implements P2 from refactoring plan for updater safety.
- Create new cmd/mcpproxy-tray binary for macOS system tray - Add HTTP API endpoints in internal/api/handlers.go for inter-process communication - Implement SSE (Server-Sent Events) for real-time status updates - Create HTTPServerClient adapter implementing ServerInterface via HTTP calls - Remove tray integration from core mcpproxy binary - Delete tray_gui.go and tray_stub.go build-tagged files This enables: - CGO-free core binary for better cross-platform compatibility - Independent tray binary that communicates via HTTP API - Preserved functionality while eliminating build complexity - Clean separation of concerns between core and UI Core binary now builds with CGO_ENABLED=0 for full static linking. Tray binary uses CGO for native macOS UI integration.

Phase 2 - Typed DTOs:
✅ Created internal/contracts package with typed data structures
✅ Replaced map[string]interface{} with proper contracts throughout HTTP API
✅ Added conversion functions between generic and typed data
✅ All endpoints now return strongly-typed responses
Phase 6 - Contract Tests & TypeScript Generation:
✅ Generated TypeScript types for frontend from Go contracts
✅ Added comprehensive contract tests with golden file validation
✅ Implemented automated type generation via cmd/generate-types
✅ Created test coverage for all API endpoints

Resolved two critical bugs causing the UI to show incorrect "Stopped" status: 1. **StatusSnapshot running state inconsistency**: - Modified runtime.StatusSnapshot() to accept serverRunning parameter - Ensures authoritative server running state is used instead of runtime copy - Updated server.GetStatus() and enqueueStatusSnapshot() calls - Fixed test cases to pass correct running state 2. **Phase transition during background initialization**: - Modified runtime background initialization to preserve "Running" phase - Added condition to prevent phase change from "Running" to "Connecting" - Server now maintains "Running" status while upstream connections happen **Impact**: SSE endpoint now correctly sends: - "running": true (was false) - "phase": "Running" (was "Connecting") **Files modified**: - internal/runtime/runtime.go: StatusSnapshot signature and logic - internal/server/server.go: GetStatus and enqueueStatusSnapshot calls - internal/runtime/lifecycle.go: Background initialization logic - internal/runtime/runtime_test.go: Test parameter updates **Testing**: All unit tests pass, SSE endpoint verified with curl
- Add context cancellation to OAuth event monitor to stop infinite loop during shutdown - Reduce stderr and process monitoring timeouts from 2s to 500ms during disconnect - Add proper shutdown context to upstream manager DisconnectAll method - OAuth event monitor now responds to context cancellation and stops cleanly - Background processes no longer hang during graceful shutdown Resolves manual testing issue where Ctrl+C would hang indefinitely due to: 1. OAuth event monitor running infinite loop without cancellation 2. Long timeouts during stderr monitoring cleanup 3. Missing shutdown coordination between components
- Add 1 second timeout to stopBackgroundMonitoring WaitGroup.Wait() - Prevents indefinite hanging during shutdown when background health check is stuck - Allows complete shutdown sequence to proceed properly - HTTP server now shuts down cleanly and process exits completely This resolves the issue where Ctrl+C would stop upstream connections but never reach HTTP server shutdown, leaving the process running and accepting new connections without returning control to terminal.
- Prevents caching files from being tracked in version control - Ensures a cleaner repository and avoids unnecessary clutter
Remove global 60-second timeout middleware that was causing SSE connections to terminate prematurely. Apply timeout selectively to API routes only, keeping SSE endpoint unrestricted. Add 30-second heartbeat mechanism to SSE handler to maintain connection stability and prevent proxy/load balancer timeouts. This resolves periodic reconnect messages in the web UI.
- Fix frontend status reading to check top-level running field first - Fix HTTP server shutdown by running ListenAndServe in goroutine with context - Add force quit mechanism on second Ctrl+C signal within 10 seconds - Improve graceful shutdown handling with proper timeout - Add debug logging for SSE status updates to help diagnose issues Resolves critical UI status display showing 'Stopped 0/0 servers' when running Resolves Ctrl+C not freeing shell due to HTTP server blocking shutdown
- Add troubleshooting entries for the fixed UI status and shutdown issues - Improve Servers.vue empty state message formatting - Enhance Settings.vue with comprehensive settings management UI - Add documentation for force quit mechanism and status display fixes
Updated NavBar component to use the SVG logo from assets directory instead of the text-based placeholder for better branding.
Implement comprehensive secrets management system for secure storage
of API keys, tokens, and other sensitive configuration values using
the operating system's native keyring (Keychain/Secret Service/WinCred).
Core Features:
- SecretRef syntax: ${env:NAME}, ${keyring:alias} for config files
- Multi-provider architecture (Environment, OS Keyring)
- Secret resolution with automatic expansion in configurations
- Automatic detection and analysis of potential secrets for migration
CLI Commands:
- mcpproxy secrets set/get/del/list - Full secrets lifecycle management
- mcpproxy secrets migrate - Analyze and migrate plaintext secrets
REST API:
- GET /api/v1/secrets/refs - List secret references (values masked)
- POST /api/v1/secrets/migrate - Migration analysis (dry-run only)
Web UI:
- New Secrets page (/secrets) for managing stored secrets
- Display unresolved references and migration candidates
- Integration with system keyring via CLI workflows
Security:
- No plaintext secrets in config files or logs
- All secret values masked in API responses and UI
- OS keyring integration for cross-platform security
- Automatic secret detection with confidence scoring
Dependencies:
- Added zalando/go-keyring for cross-platform keyring support
Tests:
- Comprehensive unit tests for all secret resolution components
- Mock providers for testing secret operations
- Parser and resolver functionality validation
This implementation fulfills P8-SEC requirements for secure secret
storage and provides a foundation for eliminating plaintext secrets
from MCPProxy configurations.
