smart-mcp-proxy/mcpproxy-go v0.46.0 on GitHub

This release introduces Profiles v2, enabling users to manage multiple MCP server configurations and switch between them dynamically, plus enhanced security isolation options.

New Features

Profiles v2 (Teams edition)

Per-profile tool indexes: Each profile now maintains its own Bleve search index for faster, isolated tool discovery
Profile switching via MCP tool: Agents can now switch profiles programmatically using the new set_profile MCP tool
Profile management REST API: New /api/v1/profiles endpoint for profile CRUD operations
Profile pinning per agent token: Pin specific agents to profiles with server-side enforcement to prevent unauthorized profile switching
Real-time profile updates: Server-Sent Events (SSE) broadcast active profile changes to connected clients
Web UI profile switcher: New header control for selecting active profiles in the dashboard

Profiles v2 (Personal edition)

System tray profile switcher: Quick profile switching directly from the macOS/Windows system tray menu

Security & Isolation

Configurable isolation modes: New isolation.mode enum setting allows choosing between Docker, Landlock, or no sandboxing
Landlock sandbox (experimental): Proof-of-concept Linux kernel-based sandboxing for MCP servers without Docker dependency
Per-server initialize timeout: Configure custom MCP protocol initialization timeouts for individual servers to handle slow-starting tools

Bug Fixes

Fixed index pagination when rebuilding or clearing per-profile indexes that exceed search page limits

Improvements

Mode-aware server selector automatically filters available servers based on configured isolation mode
Enhanced observability with proper user_id and profile label values in metrics (Teams edition)
