Improved monitoring and deployment automation for vMCP and Registry Server

This week ToolHive added production-ready features that teams need for enterprise deployment: audit logging and health monitoring for vMCP, API-driven registry management, and direct registry connections in the UI.

Virtual MCP Server: Audit logging, health checking, and composite tool improvements​

vMCP adds more operational capabilities that teams need for production deployments:

  • Health monitoring tracks which MCP servers behind vMCP are available and responding, the foundation for building alerts and dashboards that keep your AI workflows running smoothly.
  • Audit logging captures workflow events (started, completed, failed) via CRD configuration, giving you the compliance trail and debugging context required for regulated environments.
  • Composite tools are more powerful: Reference deeply nested fields using {{.steps.X.output.field.nested}} syntax, and use the new fromJson function to work with MCP servers (like GitHub) that return JSON as plain text. This enables cleaner conditional logic and more flexible workflows.

ToolHive Registry Server: API management and deployment improvements​

Managing registries is now more flexible and automated:

  • API-based management lets you add, update, or remove registries programmatically, useful for CI/CD pipelines and infrastructure-as-code approaches.
  • Simplified authentication: Configure auth settings directly in the Registry CRD instead of managing separate configuration files. Database credentials specified in the CRD automatically provision pgpass files, reducing manual setup.
  • Kubernetes deployment: A new Helm chart (publishing soon) makes cluster deployments more straightforward.

ToolHive UI: Live registry connections​

The ToolHive UI now connects directly to standards-compliant registry API servers like the ToolHive Registry Server. Instead of importing static JSON files, you get live registry data, making it easier to browse and discover available MCP servers in your environment.
