MCP Server for Kubernetes Support Bundles

A Model Context Protocol (MCP) server for AI models to interact with Kubernetes support bundles. This server enables AI models to analyze and troubleshoot Kubernetes clusters by exploring support bundles generated by the Troubleshoot tool.

Features

• 🚀 Bundle Management: Initialize and manage Kubernetes support bundles
• 🎮 Command Execution: Run kubectl commands against bundle's API server
• 📁 File Explorer: Navigate and search files within the bundle
• 🔐 Secure Authentication: Token-based authentication for bundle access
• 🐳 Container Support: Run as a containerized application

Quick Start

Using Podman

The easiest way to get started is using Podman:

# Build the image (uses melange/apko instead of Containerfile)
./scripts/build.sh

# Run the server
podman run -i --rm \
  -v "/path/to/bundles:/data/bundles" \
  -e SBCTL_TOKEN="your-token" \
  troubleshoot-mcp-server-dev:latest

See the for comprehensive container configuration details.

Manual Installation

1. Ensure you have Python 3.13 installed
2. Set up environment with UV (recommended):

# Automatically creates and sets up environment with best available Python
./scripts/setup_env.sh

# OR create manually with UV
uv venv -p python3.13 .venv
uv pip install -e ".[dev]"  # For development with testing tools

3. Set up your authentication token:

export SBCTL_TOKEN=your-token

4. Run the server using UV:

uv run python -m troubleshoot_mcp_server

Container Image Variants

This project provides two distinct container image variants:

Development Image: troubleshoot-mcp-server-dev:latest

• Purpose: Local development and testing
• Built by: ./scripts/build.sh (default)
• Usage: When building from source or developing locally
• Example:

  ./scripts/build.sh
  podman run -i --rm troubleshoot-mcp-server-dev:latest
  

Production Image: troubleshoot-mcp-server:latest

• Purpose: Official releases and production deployments
• Built by: CI/CD pipeline with IMAGE_NAME=troubleshoot-mcp-server ./scripts/build.sh
• Usage: In production environments or when using official releases
• Example:

  IMAGE_NAME=troubleshoot-mcp-server ./scripts/build.sh
  podman run -i --rm troubleshoot-mcp-server:latest
  

Why Two Variants?

The -dev suffix prevents conflicts between local development images and official production releases. This allows users to:

• Use official container releases without interference from local builds
• Develop and test locally without overwriting production images
• Maintain clear separation between development and production environments

Tools

The MCP server provides the following tools for AI models:

Bundle Management

• initialize_bundle: Initialize a support bundle for use

Kubectl Commands

• kubectl: Execute kubectl commands against the bundle

File Operations

• list_files: List files and directories
• read_file: Read file contents
• grep_files: Search for patterns in files

Example Usage

AI models can interact with the server using the MCP protocol:

// Request to list files
{
  "name": "list_files",
  "input": {
    "path": "/kubernetes/pods",
    "recursive": false
  }
}

// Response (simplified)
{
  "content": "Listed files in /kubernetes/pods non-recursively:\n```json\n[\n  {\n    \"name\": \"kube-system\",\n    \"path\": \"/kubernetes/pods/kube-system\",\n    \"type\": \"directory\",\n    \"size\": null,\n    \"modified\": \"2025-04-10T12:30:45Z\"\n  },\n  {\n    \"name\": \"pod-definition.yaml\",\n    \"path\": \"/kubernetes/pods/pod-definition.yaml\",\n    \"type\": \"file\",\n    \"size\": 1254,\n    \"modified\": \"2025-04-10T12:30:45Z\"\n  }\n]\n```\nDirectory metadata:\n```json\n{\n  \"path\": \"/kubernetes/pods\",\n  \"recursive\": false,\n  \"total_files\": 1,\n  \"total_dirs\": 1\n}\n```"
}

Testing

# Run all tests
uv run pytest

# Run with verbose output
uv run pytest -v

# Run a specific test type using markers
uv run pytest -m unit
uv run pytest -m integration
uv run pytest -m functional  # MCP protocol validation
uv run pytest -m e2e

# Run tests with detailed warnings
uv run pytest -W all

# Run tests with warnings as errors
uv run pytest -W error

# Or use the helper script
./scripts/run_tests.sh unit
./scripts/run_tests.sh integration

Requirements

• Python 3.13
