📦 MCP Box

A local Kubernetes playground for Model Context Protocol (MCP) servers, powered by Kind, the MCP Lifecycle Operator, and MCP Gateway.

Spin up a fully working MCP environment on your machine — a Kind cluster, Gateway API with Istio, the MCP Gateway for federated tool access, and the MCP Launcher web UI for browsing and deploying MCP servers from a catalog.

✨ Features

• 🌐 MCP Gateway — Federated access to all MCP servers through a single endpoint
• 🚪 Gateway API + Istio — Envoy-based gateway with ext_proc routing, no service mesh required
• 🚀 MCP Launcher — Web UI to browse, configure, and deploy MCP servers from a catalog
• 🔌 Auto-registration — Launcher automatically creates HTTPRoute and MCPServerRegistration for each deployed server
• 🧩 MCP Lifecycle Operator — Manages MCP server pods via MCPServer custom resources
• 📦 Single command setup — ./mcp-box.sh gets you from zero to a working MCP gateway

📋 Prerequisites

• Kind installed
• kubectl installed
• A container runtime — Podman (Linux) or Docker (macOS)

🚀 Getting Started

Run everything with a single command:

./mcp-box.sh

This installs the full platform: Kind cluster, MCP Lifecycle Operator, Istio, MCP Gateway, and the Launcher UI.

➕ Optional: Kubernetes MCP Server

Deploy the Kubernetes MCP Server with gateway integration (kube_ tool prefix):

./scripts/05-kubernetes-mcp-server.sh

🔧 Gateway infrastructure only

Use install-base.sh to set up the gateway stack without the Launcher:

./install-base.sh

📁 Individual Scripts

./scripts/00-installer-kind.sh          # 1️⃣  Create Kind cluster (NodePort on 7001)
./scripts/01-mcp-lifecycle-operator.sh  # 2️⃣  Install MCP Lifecycle Operator
./scripts/02-gateway-api-istio.sh       # 3️⃣  Install Istio as Gateway API provider
./scripts/03-mcp-gateway.sh            # 4️⃣  Install MCP Gateway
./scripts/04-mcp-launcher.sh           # 5️⃣  Deploy MCP Launcher (web UI + catalog)
./scripts/05-kubernetes-mcp-server.sh  # 6️⃣  Deploy Kubernetes MCP Server (optional)

🔍 What Each Script Does

Script	Description
mcp-box.sh	🎁 Wrapper that runs scripts 00–04 in order
install-base.sh	🔧 Runs scripts 00–03 (gateway infrastructure only)
00-installer-kind.sh	🏗️ Creates a Kind cluster with NodePort mapping (host 7001 → container 30080), patches CoreDNS for external resolution
01-mcp-lifecycle-operator.sh	⚙️ Installs the MCP Lifecycle Operator and waits for readiness
02-gateway-api-istio.sh	🚪 Installs Istio as a Gateway API provider (no service mesh, just the gateway)
03-mcp-gateway.sh	🌐 Installs MCP Gateway (broker, router, controller) with NodePort service
04-mcp-launcher.sh	🚀 Installs the MCP Launcher web UI with sample catalog entries
05-kubernetes-mcp-server.sh	🧩 Deploys the Kubernetes MCP Server with HTTPRoute + MCPServerRegistration (kube_ prefix). Not run by mcp-box.sh

✅ Verifying the Setup

Check that all pods are running:

kubectl get pods -A

Check registered MCP servers on the gateway:

kubectl get mcpserverregistrations.mcp.kagenti.com -A

🌐 Accessing the Gateway

The gateway is exposed via NodePort on localhost:7001:

http://localhost:7001/mcp

Or via port-forward:

kubectl port-forward -n gateway-system svc/mcp-gateway-istio 8001:8080
# → http://localhost:8001/mcp

🚀 Accessing the MCP Launcher

kubectl port-forward -n mcp-system svc/mcp-launcher 9090:8080

Then open http://localhost:9090 in your browser.

🔎 MCP Inspector

Test the gateway with the MCP Inspector:

podman run --rm --network host ghcr.io/modelcontextprotocol/inspector:latest

Open http://localhost:6274 and connect to http://localhost:7001/mcp.

🧹 Cleanup

Delete the entire Kind cluster:

kind delete cluster
