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)

v0.0.92

🌟 Release Highlights

This release focuses on developer experience improvements with a significant internal refactoring that makes the codebase easier to maintain and extend.

🔧 Developer Experience

Modular Flag and Config Registration (#575)

We've restructured the CLI flag and configuration registration system to dramatically reduce merge conflicts during parallel development:

• Decentralized flag registration: Each flag now lives in its own file with self-contained initialization
• Plugin-style architecture: Add new flags without touching shared files by creating flags_myfeature.go
• Cleaner codebase: Reduced coupling between CLI components across 15 files
• Conflict-free collaboration: Multiple developers can now add flags simultaneously without merge headaches

Developer Impact: This architectural improvement makes MCP Gateway easier to extend and maintain, especially important as we continue rapid development. Contributors can now add new CLI flags, configuration options, or features with minimal risk of conflicts.

v0.0.90

🌟 Release Highlights

This release focuses on improving documentation accuracy and enhancing payload handling for AI agents working with large tool responses.

✨ What's New

Session-Segmented Payload Directory (#569)

• Added configurable payload directory with session-based organization
• Enables agents to mount their session-specific subdirectory ({payload_dir}/{sessionID}/) for direct access to full tool response payloads
• Payloads stored as: {payload_dir}/{sessionID}/{queryID}/payload.json
• Configurable via --payload-dir flag, MCP_GATEWAY_PAYLOAD_DIR env var, or payload_dir in config
• Default location: /tmp/jq-payloads
• The jq middleware now returns: preview (first 500 chars), schema, payloadPath, queryID, originalSize, and truncated flag

This enhancement improves handling of large MCP tool responses by storing full payloads on disk while returning concise summaries to agents. Agents can then access the complete data when needed by mounting their session-specific directory.

📚 Documentation

Documentation Accuracy Improvements (#568)

• Fixed documentation to accurately reflect the current implementation
• Ensured consistency between docs and actual gateway behavior
