+title: Introducing Registry Server and Virtual MCP Server
+sidebar_label: Registry Server & vMCP
+description:
+  Introducing the ToolHive Registry Server, Virtual MCP Server (vMCP), and new
+  management features for the ToolHive UI
+---
+
+A big week for ToolHive: we shipped a new **Registry Server** for managing and
+curating MCP servers at scale, expanded the **ToolHive UI** with registry-based
+installs and richer tool controls, and introduced **Virtual MCP Server (vMCP)**
+for consolidating many MCP backends into one secure, workflow-aware endpoint.
+
+{/* truncate */}
+
+### ToolHive Registry Server: Unified registry management and discovery
+
+ToolHive now includes a dedicated [Registry Server](/toolhive/guides-registry/)
+that aggregates multiple registry sources, keeps them in sync, and helps teams
+publish a curated "desired" registry. This enables you to:
+
+- Connect multiple registry backends (Git repositories, local or remote files,
+  internally-managed entries, Kubernetes workloads, or upstream MCP Registry API
+  servers).
+- Auto-discover MCP servers deployed in Kubernetes.
+- Automatically synchronize changes across registry sources.
+- Curate what users see via include/exclude filtering.
+- Use an authenticated
+  [cloud-based UI](https://github.com/stacklok/toolhive-cloud-ui) to view
+  running MCP servers.
+
+### ToolHive UI: Registry groups and tool customization (GA)
+
+The [ToolHive UI](/toolhive/guides-ui/) gained new features to standardize
+installs and tailor tool experiences. You can now:
+
+- Install **MCP server groups** directly from a custom registry.
+- **Customize tools** to disable unnecessary tools and edit their names and
+  descriptions for better AI performance and token/cost savings.
+
+### Virtual MCP Server: One endpoint for many servers and workflow automation
+
+[Virtual MCP Server (vMCP)](/toolhive/guides-vmcp/) simplifies operating many
+MCP servers in Kubernetes and building cross-system workflows. It enables you
+to:
+
+- Aggregate multiple MCP servers behind a single endpoint and automatically
+  resolve tool name conflicts.
+- Define declarative, multi-step tool workflows with parallel execution,
+  conditionals, error handling, and approval gates.
+- Filter, rename, and wrap upstream tools to enforce policies and present
+  simpler interfaces.
+- Pre-configure defaults for common parameters to reduce repetition and prevent
+  mistakes.
+- Separate auth boundaries: clients authenticate once to vMCP while vMCP manages
+  backend credentials for SSO, centralized access control, and auditing.
+
+### Ecosystem updates
+
+The ToolHive ecosystem continues to grow with support for new clients and MCP
+server integrations.
+
+Client support:
+
+- **Zed**: ToolHive now supports managing MCP configurations in Zed
+
+New MCP servers in the built-in registry:
+
+- **PagerDuty**: Monitor and manage incidents
+- **Prometheus**: Query metrics and monitor systems
+- **Redfish** (from Nokia): Manage server hardware
+- **SonarQube**: Analyze code quality
+- **ToolHive Documentation Search**: Search ToolHive docs directly
+
