+# KMCP Helm Chart
+
+A Helm chart for deploying the KMCP (Kubernetes MCP Server Controller) to Kubernetes clusters.
+
+## Overview
+
+KMCP is a Kubernetes controller that manages MCP (Model Context Protocol) servers. It provides a declarative way to deploy and manage MCP servers in your Kubernetes environment.
+
+## Prerequisites
+
+- Kubernetes 1.11.3+
+- Helm 3.0+
+
+## Installation
+
+### Add the Helm Repository
+
+```bash
+# Add the repository (once available)
+helm repo add kmcp https://charts.kagent.dev
+helm repo update
+```
+
+### Install the Chart
+
+```bash
+# Install with default values
+helm install kmcp kmcp/kmcp
+
+# Install in a specific namespace
+helm install kmcp kmcp/kmcp --namespace kmcp-system --create-namespace
+
+# Install with custom values
+helm install kmcp kmcp/kmcp --values values.yaml
+```
+
+## Configuration

+| `controller.metrics.enabled` | Enable metrics endpoint | `true` |
+| `controller.metrics.bindAddress` | Metrics bind address | `:8443` |
+
+### RBAC Configuration
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `rbac.create` | Create RBAC resources | `true` |
+| `serviceAccount.create` | Create service account | `true` |
+| `serviceAccount.name` | Service account name | `""` (generated) |
+| `serviceAccount.annotations` | Service account annotations | `{}` |
+
+### Resource Configuration
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `resources.limits.cpu` | CPU limit | `500m` |
+| `resources.limits.memory` | Memory limit | `128Mi` |
+| `resources.requests.cpu` | CPU request | `10m` |
+| `resources.requests.memory` | Memory request | `64Mi` |
+
+### Security Configuration
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `podSecurityContext.runAsNonRoot` | Run as non-root user | `true` |

+
+### Custom Resource Definition
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `crd.create` | Create CRDs | `true` |
+
+## Usage
+
+After installation, you can create MCP servers using the `MCPServer` custom resource:
+
+```yaml
+apiVersion: kagent.dev/v1alpha1
+kind: MCPServer
+metadata:
+  name: my-mcp-server
+spec:
+  transportType: http
+  deployment:
+    image: my-mcp-server:latest
+    port: 8080
+  httpTransport:
+    targetPort: 8080
+```
+
+## Monitoring
+
+The controller exposes metrics on port 8443 by default. These metrics can be scraped by Prometheus or other monitoring systems.
+
+## Upgrading
+
+To upgrade the chart:
+
+```bash
+helm upgrade kmcp kmcp/kmcp
+```
+
+## Uninstalling
+
+To uninstall the chart:
+
+```bash
+helm uninstall kmcp
+```
+
+**Note**: This will remove all the Kubernetes resources associated with the chart and delete the release.
