Quick Start

Get started with LUMINO in under 2 minutes:

For Claude Code CLI Users (Easiest)

Simply ask Claude Code to provision the Lumino MCP server for you by pasting this prompt:

Provision the Lumino MCP server as a project-local MCP integration:

1. Clone the repository: git clone https://github.com/spre-sre/lumino-mcp-server.git

1. Install Python dependencies using uv: cd lumino-mcp-server && uv sync

1. Create .mcp.json in the current project root (NOT inside lumino-mcp-server) with this configuration. IMPORTANT: Replace with the actual absolute path to the cloned lumino-mcp-server directory:

{ "mcpServers": { "lumino": { "type": "stdio", "command": " /.venv/bin/python", "args": [" /main.py"], "env": { "PYTHONUNBUFFERED": "1" } } } }

1. After creating .mcp.json, inform the user to:

• Exit Claude Code completely
• Connect to their Kubernetes or OpenShift cluster (kubectl/oc login)
• Restart Claude Code in this project directory
• They will see a prompt to approve the Lumino MCP server
• Once approved, Lumino tools will be available (check with /mcp command)

For Other MCP Clients

Choose your preferred installation method:

• MCPM (Recommended): mcpm install @spre-sre/lumino-mcp-server
• Manual Setup: See detailed MCP Client Integration instructions

Verify Installation

Once installed, test with a simple query:

"List all namespaces in my Kubernetes cluster"

Prerequisites

Required

• Python 3.10 or higher - Core runtime
• MCP Client - One of:
• Claude Desktop
• Claude Code CLI
• Gemini CLI
• Cursor IDE

For Kubernetes Features

• Kubernetes/OpenShift Access - Valid kubeconfig with read permissions
• RBAC Permissions - Ability to list pods, namespaces, and other resources

Optional (Recommended)

• [uv](https://docs.astral.sh/uv/) - Faster dependency management than pip
• [MCPM](https://github.com/spre-sre/mcpm) - Easiest installation experience
• Prometheus - For advanced metrics and forecasting features

Installation

Using uv (recommended)

# Clone the repository

git clone https://github.com/spre-sre/lumino-mcp-server.git cd lumino-mcp-server

Install dependencies

uv sync

Run the server

uv run python main.py

Using pip

# Clone the repository

git clone https://github.com/spre-sre/lumino-mcp-server.git cd lumino-mcp-server

Create virtual environment

python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate

Install dependencies

pip install -e .

Run the server

python main.py

Usage

Local Mode (stdio transport)

By default, the server runs in local mode using stdio transport, suitable for direct integration with MCP clients:

python main.py

Kubernetes Mode (HTTP streaming transport)

When running inside Kubernetes, set the namespace environment variable to enable HTTP streaming:

export KUBERNETES_NAMESPACE=my-namespace

python main.py

The server automatically detects the environment and switches transport modes.

Usage Examples

🔍 Intelligent Root Cause Analysis

Investigate and diagnose complex failures with automated analysis:

"Generate a comprehensive RCA report for the failed pipeline run 'build-api-pr-456' in namespace ci-cd"

"Analyze what caused pod crashes in namespace production over the last 6 hours and correlate with resource events"

"Investigate the TLS certificate issues affecting services in namespace ingress-nginx"

🎯 Predictive Intelligence & Forecasting

Anticipate problems before they impact your systems:

"Predict resource bottlenecks across all production namespaces for the next 48 hours"

"Analyze historical pipeline performance and detect anomalies in build times for the last 30 days"

"Check cluster certificate health and alert me about any certificates expiring in the next 60 days"

"Use predictive log analysis to identify potential failures in namespace monitoring before they occur"

🧪 Simulation & What-If Analysis

Test changes safely before applying them to production:

"Simulate the impact of increasing memory limits to 4Gi for all pods in namespace backend-services"
