+## MCP Gateway
+
+[MCP Gateway](https://portkey.ai/docs/product/mcp-gateway) provides a centralized control plane for managing MCP (Model Context Protocol) servers across your organization.
+
+- **Authentication** — Single auth layer at the gateway. Users authenticate once; your MCP servers receive verified requests
+- **Access Control** — Control which teams and users can access which servers and tools. Revoke access instantly
+- **Observability** — Every tool call logged with full context: who called what, parameters, response, latency
+- **Identity Forwarding** — Forward user identity (email, team, roles) to MCP servers automatically
+
+Works with Claude Desktop, Cursor, VS Code, and any MCP-compatible client. [Get started →](https://portkey.ai/docs/product/mcp-gateway/quickstart)
