+description:
+  Improved proxy configuration in the ToolHive UI, bearer token authentication
+  for remote servers, backend health monitoring for vMCP, and MCP client sync
+  from Cloud UI.
+---
+
+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.
