Quick Start

English | Espanol

Prerequisites

OpenShift cluster with OLS (OpenShift Lightspeed) installed
oc CLI authenticated to the cluster
helm CLI (optional, for Helm-based installation)

Option 1: Helm Chart (recommended)

helm repo add showroom-docs-mcp \
  https://maximilianopizarro.github.io/showroom-docs-mcp/

helm install showroom-docs-mcp showroom-docs-mcp/showroom-docs-mcp \
  --namespace openshift-lightspeed \
  --set image.pullPolicy=Always

Helm Chart Values

The chart includes a values.schema.json for input validation. Key configurable values:

Parameter	Default	Description
`replicaCount`	`1`	Number of replicas
`image.repository`	`quay.io/maximilianopizarro/showroom-docs-mcp`	Container image
`image.tag`	`latest`	Image tag
`image.pullPolicy`	`Always`	Pull policy (`Always`, `IfNotPresent`, `Never`)
`namespace`	`openshift-lightspeed`	Target namespace
`service.type`	`ClusterIP`	Service type
`service.port`	`8080`	Service port
`resources.requests.cpu`	`100m`	CPU request
`resources.requests.memory`	`256Mi`	Memory request
`resources.limits.cpu`	`500m`	CPU limit
`resources.limits.memory`	`512Mi`	Memory limit
`inspector.enabled`	`true`	Enable MCP Inspector deployment
`inspector.route.timeout`	`300s`	Route timeout for MCP connections
`olsConfig.enabled`	`false`	Enable OLSConfig integration
`olsConfig.mcpServerName`	`showroom-docs-mcp`	MCP server name in OLSConfig
`olsConfig.mcpServerTimeout`	`10`	MCP timeout (seconds)

Example with custom values:

helm install showroom-docs-mcp showroom-docs-mcp/showroom-docs-mcp \
  --namespace openshift-lightspeed \
  --set image.pullPolicy=Always \
  --set resources.limits.memory=1Gi \
  --set replicaCount=2

Option 2: Direct Manifests

# Clone the repository
git clone https://github.com/maximilianoPizarro/showroom-docs-mcp.git
cd showroom-docs-mcp

# Apply manifests
oc apply -f k8s/deployment.yaml

Configure OLSConfig

Add the MCP server to your OLSConfig. Note: use /mcp (Streamable HTTP), not /mcp/sse:

apiVersion: ols.openshift.io/v1alpha1
kind: OLSConfig
metadata:
  name: cluster
spec:
  featureGates:
    - MCPServer
  mcpServers:
    - name: showroom-docs-mcp
      timeout: 10
      url: 'http://showroom-docs-mcp.openshift-lightspeed.svc.cluster.local:8080/mcp'

Apply:

oc apply -f cluster-ols.yml

The OLS operator will automatically restart pods with the new configuration.

Verify

# Check that the pod is running
oc get pods -n openshift-lightspeed -l app=showroom-docs-mcp

# Verify health
oc exec -n openshift-lightspeed deploy/showroom-docs-mcp -- \
  curl -s http://localhost:8080/q/health/ready

# Check logs (should show no errors)
oc logs -n openshift-lightspeed -l app=showroom-docs-mcp

# Verify MCP tools are loaded by OLS
oc logs -n openshift-lightspeed deploy/lightspeed-app-server \
  -c lightspeed-service-api | grep "showroom-docs-mcp"

Test

Once deployed, open the OpenShift Lightspeed chat in the console and try these questions:

Red Hat Product Questions

“How do I install OpenShift Service Mesh 3.3?”
“Explain the architecture of Red Hat Developer Hub”
“What are the steps to deploy a model with OpenShift AI?”
“How do I configure Connectivity Link gateway policies?”
“How do I set up OpenTelemetry collectors for distributed tracing?”
“How does OpenShift Lightspeed OLSConfig work?”
“How do I create a Tekton pipeline with Pipelines as Code?”
“How do I manage APIs with Red Hat OpenShift API Management?”
“What monitoring tools are available in OpenShift Observability?”

Neuralbank Workshop Questions

“What is the Neuralbank workshop about?”
“How do I build an MCP agent with Quarkus?”
“Explain the Golden Path template in Developer Hub”
“How is Keycloak used for user management in the workshop?”
“What is RAG and how does it work with vector databases?”
“How do I use DevSpaces for development?”

Architecture Overview

Architecture: OpenShift Lightspeed + MCP

Developer Sandbox Quick Start

For Red Hat Developer Sandbox, deploy the MCP server with the Inspector to test tools with Granite:

helm repo add showroom-docs-mcp \
  https://maximilianopizarro.github.io/showroom-docs-mcp/

helm install showroom-docs-mcp showroom-docs-mcp/showroom-docs-mcp \
  --set namespace=$(oc project -q) \
  --set image.pullPolicy=Always

The Inspector auto-connects to the MCP server. To enable the LiteLLM proxy for OpenAI-compatible access to Granite:

helm upgrade showroom-docs-mcp showroom-docs-mcp/showroom-docs-mcp \
  --set namespace=$(oc project -q) \
  --set litellm.enabled=true \
  --set litellm.granite.apiKey=$(oc whoami -t)

Test the proxy:

LITELLM_HOST=$(oc get route showroom-docs-mcp-litellm -o jsonpath='{.spec.host}')

curl -s https://${LITELLM_HOST}/v1/chat/completions \
  -H "Authorization: Bearer sk-showroom-mcp-1234" \
  -H "Content-Type: application/json" \
  -d '{"model":"granite","messages":[{"role":"user","content":"Hello"}]}'

Note: The OAuth token expires after ~24h. Refresh with --set litellm.granite.apiKey=$(oc whoami -t).
