## 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

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

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

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

4. 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](#mcp-client-integration) instructions

### Verify Installation

Once installed, test with a simple query:

```
"List all namespaces in my Kubernetes cluster"
```

## Prerequisites

- **MCP Client** - One of:
  - [Claude Desktop](https://claude.ai/download)
  - [Claude Code CLI](https://github.com/anthropics/claude-code)
  - [Gemini CLI](https://github.com/google/generative-ai-cli)
  - [Cursor IDE](https://cursor.sh/)

### 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)

```bash
# 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

```bash
# 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:

```bash
python main.py
```

### Kubernetes Mode (HTTP streaming transport)

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

```bash
export KUBERNETES_NAMESPACE=my-namespace
python main.py
```

The server automatically detects the environment and switches transport modes.

### Workflow

1. **User Query** → AI assistant receives natural language request
2. **MCP Translation** → Assistant converts query to appropriate tool calls
3. **LUMINO Processing** → Server executes Kubernetes/Prometheus operations
4. **Data Analysis** → ML/statistical algorithms process raw data
5. **AI Synthesis** → Assistant formats results into human-readable insights

### Key Features

- **Stateless Design** - No data persistence, queries cluster in real-time
- **Automatic Transport Detection** - Switches between stdio (local) and HTTP (K8s) modes
- **Token Budget Management** - Adaptive strategies to handle large log volumes
- **Intelligent Caching** - Smart caching for frequently accessed data
- **Security First** - Uses existing kubeconfig RBAC permissions, no separate auth

## MCP Client Integration

### Method 1: Using MCPM (Recommended for Claude Code CLI / Gemini CLI)

The easiest way to install LUMINO MCP Server for Claude Code CLI or Gemini CLI is using [MCPM](https://github.com/spre-sre/mcpm) - an MCP server package manager.

#### Install MCPM

```bash
# Clone and build MCPM
git clone https://github.com/spre-sre/mcpm.git
cd mcpm
go build -o mcpm .

# Optional: Add to PATH
sudo mv mcpm /usr/local/bin/
```

**Requirements**: Go 1.23+, Git, Python 3.10+, uv (or pip)

#### Install LUMINO MCP Server

```bash
# Install from GitHub repository (short syntax)
mcpm install @spre-sre/lumino-mcp-server

# Or use full GitHub URL
mcpm install https://github.com/spre-sre/lumino-mcp-server.git

# For GitLab repositories (if hosted on GitLab)
mcpm install gl:@spre-sre/lumino-mcp-server

# Install for specific client
mcpm install @spre-sre/lumino-mcp-server --claude  # For Claude Code CLI
mcpm install @spre-sre/lumino-mcp-server --gemini  # For Gemini CLI

# Install globally (works with both Claude and Gemini)
mcpm install @spre-sre/lumino-mcp-server --global
```

**Short syntax explained**:
- `@owner/repo` - Installs from GitHub (default: `https://github.com/owner/repo.git`)
- `gl:@owner/repo` - Installs from GitLab (`https://gitlab.com/owner/repo.git`)
- Full URL - Works with any Git repository

This will:
- Clone the repository to `~/.mcp/servers/lumino-mcp-server/`
- Auto-detect Python project and install dependencies using `uv` (or pip)
- Register with Claude Code CLI or Gemini CLI configuration automatically

#### Manage LUMINO

```bash
# List installed servers
mcpm list

# Update LUMINO
mcpm update lumino-mcp-server

# Remove LUMINO
mcpm remove lumino-mcp-server
```

      "env": {
        "PYTHONUNBUFFERED": "1"
      }
    }
  }
}
```

**Important**: Replace `/absolute/path/to/lumino-mcp-server` with the actual absolute path where you cloned the repository (e.g., `/Users/username/projects/lumino-mcp-server`).

3. **Verify installation**:

```bash
# Check MCP servers
claude mcp list

# Test with a query
claude "List all namespaces in my cluster"
```

In Cursor's MCP settings, add:

```json
{
  "mcpServers": {
    "lumino": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/lumino-mcp-server",
        "python",
        "main.py"
      ],
      "env": {
        "PYTHONUNBUFFERED": "1"
      }
    }
  }
}
```

**Alternative - Using Cursor's settings.json**:

1. Open Command Palette (`Cmd+Shift+P` or `Ctrl+Shift+P`)
2. Type "Preferences: Open User Settings (JSON)"
3. Add the MCP configuration:

```json
{
  "mcp.servers": {
    "lumino": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/lumino-mcp-server",
        "python",
        "main.py"
      ],
      "env": {
        "PYTHONUNBUFFERED": "1"
      }
    }
  }
}
```

3. **Restart Cursor IDE**

4. **Verify**: Open Cursor's AI chat and check if LUMINO tools are available

### Configuration Notes

**Replace `/path/to/lumino-mcp-server`** with the actual path where you cloned the repository:

```bash
# Example paths:
# macOS/Linux: /Users/username/projects/lumino-mcp-server
# Windows: C:\Users\username\projects\lumino-mcp-server

# If installed via MCPM:
# ~/.mcp/servers/lumino-mcp-server/
```

**Environment Variables** (optional):

Add these to the `env` section if needed:

```json
{
  "env": {
    "PYTHONUNBUFFERED": "1",
    "KUBERNETES_NAMESPACE": "default",
    "PROMETHEUS_URL": "http://prometheus:9090",
    "LOG_LEVEL": "INFO"
  }
}
```

---

### Using Alternative Python Package Managers

#### With pip instead of uv

```json
{
  "command": "python",
  "args": [
    "/path/to/lumino-mcp-server/main.py"
  ]
}
```

**Note**: Ensure you've activated the virtual environment first:

```bash
cd /path/to/lumino-mcp-server
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -e .
```

#### With poetry

```json
{
  "command": "poetry",
  "args": [
    "run",
    "python",
    "main.py"
  ],
  "cwd": "/path/to/lumino-mcp-server"
}
```

### Testing Your Configuration

After configuring any client, test the connection:

1. **Check if tools are loaded**:
   - Claude Desktop: Look for 🔨 hammer icon
   - Claude Code CLI: `claude mcp list`
   - Gemini CLI: `gemini mcp list`
   - Cursor: Check AI chat for available tools

2. **Test a simple query**:

```
"List all namespaces in my Kubernetes cluster"
```

3. **Check server logs** (if issues):

```bash
# Run server manually to see errors
cd /path/to/lumino-mcp-server
uv run python main.py
```

Expected output:
```
MCP Server running in stdio mode
Available tools: 37
Waiting for requests...
```

---

### Advanced Configuration

#### Multiple Clusters

Configure multiple LUMINO instances for different clusters:

```json
{
  "mcpServers": {
    "lumino-prod": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/lumino-mcp-server", "python", "main.py"],
      "env": {
        "KUBECONFIG": "/path/to/prod-kubeconfig.yaml"
      }
    },
    "lumino-dev": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/lumino-mcp-server", "python", "main.py"],
      "env": {
        "KUBECONFIG": "/path/to/dev-kubeconfig.yaml"
      }
    }
  }
}
```

#### Custom Log Level

```json
{
  "env": {
    "LOG_LEVEL": "DEBUG",
    "MCP_SERVER_LOG_LEVEL": "DEBUG"
  }
}
```

### Supported Transports

The server automatically detects the appropriate transport:

- **stdio** - For local desktop integrations (Claude Desktop, Claude Code CLI, Gemini CLI, Cursor)
- **streamable-http** - For Kubernetes deployments (when `KUBERNETES_NAMESPACE` is set)

## Performance Considerations

### Optimizing for Large Clusters

LUMINO is designed to handle clusters of any size efficiently:

| Cluster Size | Recommendation | Tool Strategy |
|--------------|----------------|---------------|
| **Small** (< 50 pods) | Use default settings | All tools work optimally |
| **Medium** (50-500 pods) | Use namespace filtering | Leverage adaptive tools with auto-sampling |
| **Large** (500+ pods) | Specify time windows and namespaces | Use conservative and streaming tools |
| **Very Large** (1000+ pods) | Combine filters and pagination | Progressive analysis with targeted queries |

### Token Budget Management

LUMINO automatically manages AI context limits:

- **Adaptive Sampling** - Smart tools auto-sample data when volumes are high
- **Progressive Loading** - Stream analysis processes data in chunks
- **Token Budgets** - Configurable limits prevent context overflow
- **Hybrid Strategies** - Automatically selects best analysis approach

### Query Optimization Tips

**Use Namespace Filtering**
```
✅ "Analyze logs for pods in namespace production"
❌ "Analyze all pod logs in the cluster"
```

**Specify Time Windows**
```
✅ "Show events from the last 2 hours"
❌ "Show all events" (might return thousands)
```

**Leverage Smart Tools**
```
✅ "smart_summarize_pod_logs" - Adaptive analysis
❌ Direct log dumps - No processing
```

**Use Progressive Analysis**
```
✅ Start with "overview" → drill down to "detailed"
❌ Jump directly to "deep_dive" on large datasets
```

### Performance Metrics

| Operation | Typical Response Time | Scalability |
|-----------|----------------------|-------------|
| List namespaces | < 1s | O(1) |
| Get pod logs (1 pod) | 1-3s | O(log size) |
| Analyze pipeline run | 2-5s | O(task count) |
| Cluster-wide search | 5-15s | O(namespace count) |
| ML anomaly detection | 3-10s | O(data points) |
| Topology mapping | 5-20s | O(resource count) |

### Caching Strategy

LUMINO uses intelligent caching for frequently accessed data:

- **15-minute cache** - For web-fetched content
- **Session cache** - For hybrid log analysis
- **No persistence** - All data queries cluster in real-time

### Concurrent Requests

The server handles multiple concurrent requests efficiently:

- **Thread-safe operations** - Safe parallel tool execution
- **Connection pooling** - Reuses Kubernetes API connections
- **Async HTTP** - Non-blocking Prometheus queries

### Resource Usage

**Server Resource Requirements**

| Deployment | CPU | Memory | Disk |
|------------|-----|--------|------|
| Local (stdio) | 100-500m | 256-512Mi | Minimal |
| Kubernetes | 200m-1 | 512Mi-1Gi | Minimal |
| High-load | 1-2 | 1-2Gi | Minimal |

**Note**: LUMINO is stateless and requires minimal resources. Most processing happens in the AI assistant.

## Troubleshooting

### Common Issues

**No Kubernetes cluster found**
```
Error: Unable to load kubeconfig
```
Ensure you have a valid kubeconfig at `~/.kube/config` or are running inside a cluster.

**Permission denied for resources**
```
Error: Forbidden - User cannot list resource
```
Check your RBAC permissions. The server needs read access to the resources you want to query.

**Tool timeout**
For large clusters, some tools may timeout. Use filtering options (namespace, labels) to reduce scope.
