v0.0.103

🌟 Release Highlights

This release enhances operational visibility with per-server logging and includes workflow stability improvements.

✨ What's New

Per-ServerID Log Files (#724)
MCP Gateway now creates separate log files for each backend server (e.g., github.log, slack.log), making it significantly easier to troubleshoot individual server issues. Logs are written to both the per-server file and the unified mcp-gateway.log for comprehensive debugging.

Better Debugging Experience:

• Find server-specific issues faster without searching through unified logs
• Thread-safe concurrent logging with automatic fallback
• Zero disruption to existing logging workflows

🔧 Test & Workflow Improvements

• Updated smoke tests to use latest gateway version (#719, #720)
• Fixed Serena MCP server image and runtime-import paths in smoke test workflow (#721)

v0.0.98

🌟 Release Highlights

This release focuses on improving Docker container management and debugging capabilities, making it easier to diagnose and troubleshoot MCP backend server issues.

✨ What's New

• Real-time Container Logs (#621): MCP Gateway now streams container stderr output in real-time during operation, not just on failures. This provides immediate visibility into backend server behavior and makes debugging significantly easier.

• Improved Docker API Compatibility (#620): The gateway now uses the Docker server's current API version instead of requiring a minimum version. This resolves compatibility issues with different Docker daemon configurations and reduces connection errors.

🔧 Performance & Reliability

• MCP Stress Testing (#616): Added comprehensive stress testing to validate gateway stability under heavy load conditions, ensuring reliable operation in production environments.

• Gateway Updates (#617, #618): Internal improvements and dependency updates to the gateway core for better stability and maintainability.

v0.0.94

🌟 Release Highlights

This release focuses on enhanced observability, testing infrastructure, and reliability for MCP Gateway. Key improvements include upgraded SDK observability, comprehensive test coverage for critical components, and refined logging capabilities.

✨ What's New

• 🔍 Enhanced SDK Observability (#590) - Upgraded to go-sdk v1.2.0, bringing improved resource management, built-in request/response logging, and better error tracking for MCP server interactions. This provides deeper visibility into backend server behavior and simplifies debugging.

• 🔐 Authentication Debug Logging (#587) - Added detailed debug logging to the authentication middleware, making it easier to troubleshoot authorization issues and track session management. Enable with DEBUG=auth:* for real-time auth flow visibility.

• 💾 Large Payload Storage (#593) - Comprehensive tests now validate the large payload storage system and session isolation. The gateway stores oversized tool responses in /tmp/jq-payloads (configurable via --payload-dir), ensuring agents can access full payloads when responses exceed size limits.

🐛 Bug Fixes & Improvements

• ✅ Test Infrastructure - Multiple improvements to test reliability:
  • Added comprehensive timeout tests for launcher operations (#578)
  • Enhanced logger package test coverage (#589)
  • Fixed linting errors and test logic in JSONL logger (#591)
  • Updated test expectations to match actual error messages (#592)
