smart-mcp-proxy/mcpproxy-go v0.48.1 on GitHub

This maintenance release fixes critical configuration persistence issues on Linux systems for the Teams edition.

Bug Fixes

Teams Edition:

Fixed web UI configuration saves on Linux by making /etc/mcpproxy writable by the service user
Resolved permission issues that prevented the MCPProxy service from persisting configuration changes through the web interface

These fixes ensure that configuration changes made through the Teams web UI are properly saved and persist across service restarts on Linux deployments.
