smart-mcp-proxy/mcpproxy-go v0.42.0 on GitHub

This release introduces enhanced control over tool approval workflows with per-server auto-approval settings and new CLI commands for managing quarantined tools.

New Features

Per-Server Auto-Approve Toggle: Configure auto-approval of tool changes independently for each MCP server through the UI (Personal & Teams)
Trust Baseline & Rug-Pull Detection: New trust-baseline approval mode automatically flags suspicious tool changes that may indicate malicious updates (Personal & Teams)
CLI Tool Management: Added tools approve and tools reject commands for managing pending quarantined tools from the command line (Personal & Teams)
Batch Tool Approval: Approve or reject multiple pending tools at once from the global Tools page (Personal & Teams)
Auto-Approve Configuration: New auto_approve_tool_changes flag replaces the deprecated skip_quarantine setting, providing clearer control over tool approval behavior (Personal & Teams)

Improvements

Tool approval settings are now exposed and persisted through the REST API for programmatic configuration (Teams)
Pending tools are now prominently displayed in the ServerDetail approval banner for better visibility (Personal & Teams)

Breaking Changes

The skip_quarantine configuration flag is deprecated in favor of auto_approve_tool_changes. Existing configurations will be automatically migrated, but you should update your config files to use the new flag name.
