smart-mcp-proxy/mcpproxy-go v0.24.0 on GitHub

This release introduces a major new security scanner plugin system and implements privacy-respecting telemetry, along with several important bug fixes.

New Features

Security Scanner Plugin System — A comprehensive plugin architecture for scanning MCP servers and tools for security vulnerabilities, enabling extensible security analysis capabilities
Telemetry tier 2 — Privacy-respecting usage signals now collected via REST API, requiring daemon for payload viewing. Telemetry configuration now properly honors the --config flag

Bug Fixes

Security scanner routing — Non-CVE security findings are now correctly routed outside the Supply Chain Audit section for better organization
Quarantine auto-approval — Fixed critical issue where quarantine_enabled=false would incorrectly auto-approve new servers without user review. This affected both editions
Feature flag emission — The enable_web_ui flag is now properly emitted alongside enable_prompts in feature flag responses
Security scanner QA — Resolved 13 quality assurance findings in the security scanner plugin system, improving reliability and accuracy
Homebrew auto-update — Personal edition Homebrew cask now automatically updates on release

Breaking Changes

Telemetry payload viewing — The show-payload command now requires the daemon to be running to serve telemetry data via REST instead of direct file access
