smart-mcp-proxy/mcpproxy-go v0.34.0 on GitHub

This release brings comprehensive configuration improvements and enhanced security features, with major usability upgrades for macOS users.

New Features

Native macOS Settings Editor (Personal Edition) - The macOS tray app now includes a full native settings interface with a REST config editor, making configuration management seamless without needing external tools (#537)
Form-Based Settings Page - New user-friendly settings page with form controls, plus PATCH /config endpoint support for partial configuration updates without overwriting entire configs (#536)
Output Schema Validation - Tool call responses are now validated against their declared output schemas (MCP Spec 054 Track A), ensuring responses conform to expected formats and catching malformed data early (#525)
Output Sanitization Enforcement - Security enhancement that sanitizes all tool outputs at the response chokepoint, providing an additional layer of protection against malicious or malformed content (#535)

Improvements

Repaired end-to-end API tests following removal of legacy 'call tool' functionality (#534)
