+# MCP Gateway Integration
+
+This guide describes how to integrate the StackRox MCP server with [MCP Gateway](https://github.com/Kuadrant/mcp-gateway), enabling tool aggregation behind a centralized gateway endpoint.
+
+## Overview
+
+MCP Gateway is an Envoy-based system that aggregates multiple MCP servers behind a single endpoint. It uses Gateway API resources and a custom `MCPServerRegistration` CRD to discover and route requests to backend MCP servers.
+
+When enabled, the Helm chart creates:
+- **HTTPRoute** — routes `/mcp` traffic from the gateway to the StackRox MCP service
+- **MCPServerRegistration** — registers the server with the gateway using a tool prefix to avoid naming conflicts
+
+## Prerequisites
+
+- [MCP Gateway](https://github.com/Kuadrant/mcp-gateway) installed on the cluster ([OpenShift installation guide](https://github.com/Kuadrant/mcp-gateway/tree/main/config/openshift))
+
+The Helm chart validates that the required CRDs are available and fails with a descriptive error if they are not.
+
+## Installation
+
+**Important:** When MCP Gateway is enabled, `replicaCount` must be set to `1`. The Gateway API's HTTPRoute bypasses Kubernetes Service-level session affinity, so multiple replicas would cause MCP client connections to land on different pods, breaking stateful MCP sessions.
+
+```bash
+helm install stackrox-mcp charts/stackrox-mcp \
+  --namespace stackrox-mcp \
+  --create-namespace \
+  --set replicaCount=1 \
+  --set mcpGateway.enabled=true \
+  --set mcpGateway.hostname=stackrox-mcp.mcp.local \
+  --set config.central.url=<your-central-url>
+```
+
+## Configuration Reference
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `mcpGateway.enabled` | Enable MCP Gateway integration | `false` |
+| `mcpGateway.gateway.name` | Name of the MCP Gateway resource | `mcp-gateway` |
+| `mcpGateway.gateway.namespace` | Namespace of the MCP Gateway resource | `gateway-system` |
+| `mcpGateway.hostname` | Internal routing hostname for the HTTPRoute | `<fullname>.mcp.local` |
+| `mcpGateway.toolPrefix` | Prefix for tools exposed via the gateway | `stackrox_` |
+
+## Verification
+
+```bash
+curl -X POST https://$(oc get routes -n gateway-system -o jsonpath='{ .items[0].spec.host }')/mcp \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","method":"initialize","id":1,"params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}'
+```
+
+## Architecture
+
+```
+MCP Client
+  → MCP Gateway (gateway-system namespace)
+    → HTTPRoute (/mcp)
+      → StackRox MCP Service (stackrox-mcp namespace)
+        → StackRox MCP Pod(s)
+          → StackRox Central API
+```
+
+The gateway aggregates tools from all registered MCP servers. StackRox MCP tools are exposed with the configured prefix (e.g., `stackrox_get_deployments_for_cve`).
