Client configuration and stability improvements
Welcome to 2026! The ToolHive team is back into the swing of things after the holiday break, focusing on improved operational resilience and streamlined developer workflows: vMCP gained backend health monitoring for production environments, the CLI and desktop UI added bearer token authorization for remote servers, the desktop UI added flexible proxy configuration, and Cloud UI now displays MCP configurations for your IDE clients, with one-click setup for Cursor.
Virtual MCP Server: Health monitoring and composite tool fixes
vMCP adds operational capabilities that teams need for production deployments:
- Backend health monitoring detects and handles unreachable servers gracefully, reducing user-facing errors when individual MCP servers restart or become temporarily unavailable.
- Composite tool fixes ensure type coercion in templates works correctly and error continuation behaves as expected, so multi-step workflows complete reliably even when intermediate steps encounter issues.
ToolHive desktop UI: Proxy configuration and stability
The desktop UI gives you more control over how MCP servers connect:
- Custom proxy ports simplify deployment in environments with specific port requirements or when running multiple instances.
- Stability improvements through upgraded core dependencies (Electron, ai-sdk) and fixes for form validation and environment variable handling reduce crashes and unexpected behavior.
Behind the scenes, we've expanded automated testing with Playwright, and work is underway to align CLI and Desktop UI versioning through bundling.
CLI and desktop UI: New auth option for remote servers
The CLI and desktop UI now support bearer token authentication for remote MCP servers, enabling secure connections to authenticated endpoints, such as enterprise APIs or hosted services, without manual credential handling in each request.
Cloud UI: Easier client setup
Cloud UI now displays client-specific configurations for MCP servers (Cursor, VS Code, and Claude Code), making setup easier. For Cursor, a single click opens the configuration directly; for VS Code and Claude Code, copy the ready-to-use config or command.
