[crivetimihai]

📦 MCP Gateway v0.1.1 – 2025‑06‑15

This is a feature-packed minor release focused on stability, packaging, wrapper enhancements, and documentation polish. It builds upon the initial public release (v0.1.0) by refining the developer experience and broadening deployment capabilities.

✨ Highlights

• 🔁 New stdio-to-SSE wrapper (mcpgateway.wrapper) that allows legacy MCP clients to interact with modern gateways
• 📦 Run as a Python module: python3 -m mcpgateway.wrapper now supported thanks to package restructure
• 🧪 /ready endpoint for Kubernetes readiness probes
• 🧬 /version API and UI tab for runtime inspection
• 🚀 Helm charts, improved Makefile and CI/CD support
• 📚 Major documentation refresh: Quick starts, pip install, Docker, FAQs, debugging tips, ArgoCD

🆕 Added

• New mcpgateway.wrapper with CLI and stdio support to connect to authenticated SSE gateways
• /version endpoint (also available via UI tab and CLI --version)
• /ready endpoint for Kubernetes readiness probes
• New Helm charts and Kubernetes deployment assets
• Improved CLI entry point via mcpgateway script (uses Uvicorn under the hood)
• Python module now supports python3 -m mcpgateway.wrapper for stdio clients
• Documentation updates: quoting advice for zsh, docker quick start, dev container, FAQ, GitHub review process, PyPi setup, ArgoCD
• Makefile targets for ArgoCD
• Initial mcpgateway.translate support to turn stdio -> SSE. More features & protocol translation options coming soon.

🐛 Fixed

• Fixed errors when deleting gateways with active metrics
• Improved gateway addition logic when tools overlap — now adds missing tools without failure
• Resolved basic authentication header bugs for tools and gateways
• Captured detailed exceptions using ExceptionGroup support for better logs
• Corrected static path resolution when installing as a wheel

📦 Packaging & Deployment

• Renamed PyPi package to avoid conflicts (mcp-contextforge-gateway)
• Enhanced Makefile with docker-run-ssl-host and new publishing targets
• Added VS Code Dev Container + GitHub Codespaces support
• Added support for APP_ROOT_PATH when reverse proxying (e.g., behind /gateway)
