v0.0.76

🌟 Release Highlights

This release brings significant improvements to configuration flexibility, security, and developer experience with enhanced CLI capabilities and better debugging tools.

✨ What's New

• Extensible Server Types: MCP Gateway now supports customSchemas for validating custom server configurations beyond the standard stdio and http types. Define your own server types with JSON schema validation for maximum flexibility. (#414)

• Enhanced CLI Experience: New Cobra-based CLI with validation hooks, verbosity control (-v/--verbose), and shell completion support for bash/zsh/fish. Get better feedback and faster workflows. (#415)

• Debug Logging Infrastructure: Added comprehensive debug logging to request handlers, making it easier to troubleshoot MCP routing and backend communication issues. Use DEBUG=server:* to see detailed request flows. (#411)

🔒 Security Improvements

• Credential Sanitization: Docker command logs now automatically sanitize sensitive environment variables (tokens, passwords, secrets) to prevent accidental credential exposure in log files. (#419)

🐛 Bug Fixes & Improvements

• Variable Expansion Fix: Environment variable expansion (${VAR_NAME}) now happens before schema validation, allowing dynamic configuration values in the container field. (#416)

• Simplified Authentication: Removed unnecessary authentication wrapper layer, clarifying the authentication flow and improving maintainability. (#418)

• Smoke Test Improvements: Updated MCP testing prompts and requirements for more reliable integration testing. (#401, #402, #403)

🧪 Testing & Quality

• Expanded Test Coverage: Added comprehensive tests for DIFC AgentRegistry and AgentLabels methods, plus improved configuration package test suite. (#405, #413)

v0.0.74

🌟 Release Highlights

A maintenance release focused on improving documentation accuracy, fixing test infrastructure, and reducing code complexity through refactoring.

🐛 Bug Fixes & Improvements

Session Management in Gateway Tests (#391)

• Fixed MCP session persistence across gateway test scenarios - session IDs now properly survive shell subprocesses and are correctly included in subsequent requests
• Enhanced Docker API version detection to dynamically query daemon capabilities instead of hardcoding versions
• Eliminated "method is invalid during session initialization" errors in test suites

Code Quality Improvements (#388)

• Reduced ~70 lines of duplicate code by centralizing authorization header parsing into auth.ExtractSessionID()
• Refactored HTTP transport connection boilerplate with function parameter pattern, making future transport additions simpler
• Improved maintainability by eliminating authorization logic duplication across routed.go and transport.go

📚 Documentation

Accurate Compatibility Information (#394)

• Updated MCP server compatibility documentation to reflect that both GitHub MCP and Serena MCP servers pass comprehensive test suites
• Added "Gateway Tests" column to compatibility tables showing both servers passing all gateway integration tests
• Removed misleading stateless vs stateful architecture discussions - both servers use identical stdio transport

Streamlined Feature Documentation (#393)

• Removed DIFC (Decentralized Information Flow Control) documentation as the feature is not yet production-ready
• Cleaned up README, AGENTS.md, and CONTRIBUTING.md to focus on supported, stable features
