+title: Token optimization goes Kubernetes-native
+sidebar_label: 'Mar 9: MCP Optimizer in K8s'
+description:
+  MCP Optimizer capabilities are now available directly inside vMCP, bringing
+  intelligent tool discovery and token reduction to Kubernetes-native
+  deployments.
+---
+
+MCP Optimizer capabilities are now embedded directly in vMCP, bringing the same
+token reduction and improved tool selection per request from desktop to
+Kubernetes-native deployments. Instead of every developer configuring a local
+optimizer instance, platform teams deploy it once and every connected client
+benefits automatically.
+
+{/* truncate */}
+
+- **On-demand tool discovery** means agents no longer receive hundreds of tool
+  descriptions in context. Instead, tools are discovered at request time and
+  only the relevant ones are surfaced (up to 8 by default, configurable) via
+  hybrid (semantic + keyword search), cutting token usage by 60-85% per request
+  while improving tool selection accuracy.
+- **Team-wide token savings from a single deployment** means the 60-85%
+  per-request reduction the Optimizer delivers on desktop now applies to every
+  developer connected to vMCP. Deploy it once, and the savings multiply across
+  the entire team without anyone managing a local optimizer instance.
+- **No per-developer configuration required.** Developers point their MCP client
+  at the vMCP endpoint and get optimized routing automatically, with no local
+  embedding models, no search parameter tuning, and no setup drift across the
+  team.
+
+The setup is GitOps-friendly: `EmbeddingServer` and `VirtualMCPServer` CRDs
+deploy through your existing CI/CD pipeline. For the full configuration
+reference and quickstart examples, check out the
+[vMCP optimizer guide](/toolhive/guides-vmcp/optimizer) to get started. For
+desktop users, MCP Optimizer remains available through the ToolHive UI and CLI
+as before.
