This release brings version visibility, better Docker control, and improved error diagnostics for MCP server connectivity issues.
New Features
- Version display and update checking: The web UI now shows the current MCPProxy version below the sidebar logo with a built-in update checker, making it easier to stay on the latest release (Teams edition)
- Per-server Docker isolation overrides: macOS users can now configure Docker isolation settings on a per-server basis through the system tray and API, providing more granular control over security quarantine (Personal edition)
Bug Fixes
- Better MCP initialization error messages: Fixed an issue where MCP server initialization failures would show generic error messages. MCPProxy now surfaces stderr output and the actual failure reason, making it much easier to diagnose connectivity and configuration problems with upstream MCP servers
