• Teams wanting AI assistants that truly understand their Jenkins setup

🚀 Quick Start

📋 Prerequisites

• Python 3.10+ (modern Python features)
• Docker & Docker Compose (production deployment)
• Jenkins API access (any version with Pipeline plugin)
• Jenkins API token (generate from user profile)

⚡ 60-Second Setup

Option 1: Install from PyPI (Recommended)

# 1. Install the package
pip install jenkins_mcp_enterprise

# Optional: enable vector/semantic search (large ML deps; not installed by default)
# pip install "jenkins_mcp_enterprise[vector]"

# 2. Create configuration file
mkdir -p config
cp config/mcp-config.example.yml config/mcp-config.yml

Option 2: Install from Source

# 1. Clone and install
git clone https://github.com/Jordan-Jarvis/jenkins-mcp-enterprise
cd jenkins-mcp
python3 -m pip install -e .

# 2. (Optional) Enable semantic/vector search
# Note: this installs large ML dependencies and runs a local Qdrant instance.
# If you skip this, vector search stays disabled by default.
python3 -m pip install -e ".[vector]"
./scripts/start_dev_environment.sh

# 3. Configure your Jenkins instances
cat > config/mcp-config.yml << 'EOF'
jenkins_instances:
  production:
    url: "https://jenkins.yourcompany.com"
    username: "[email protected]"
    token: "your-api-token"
    display_name: "Production Jenkins"
settings:
  fallback_instance: "production"
EOF

# 4. Launch the server
jenkins_mcp_enterprise --config config/mcp-config.yml

🎯 Connect to Claude Desktop

Add to ~/.claude_desktop_config.json:

{
  "mcpServers": {
    "jenkins": {
      "command": "jenkins_mcp_enterprise",
      "args": ["--config", "config/mcp-config.yml"]
    }
  }
}

That's it! Your AI assistant now has enterprise-grade Jenkins capabilities.

💬 Basic Usage Guide

Once connected to your AI assistant (Claude, etc.), you can start diagnosing build failures immediately:

🎯 Simple Build Diagnosis

Hello, will you help me diagnose why this build failed? 
https://jenkins.company.com/job/MyApp/job/feature-branch/123/

⚠️ Important: Always provide the full Jenkins URL including:

• Complete hostname (enables multi-Jenkins routing)
• Full job path with folders
• Build number

🔍 Common Usage Patterns

# Basic failure analysis
"Can you analyze this failed build? https://jenkins.company.com/job/api-service/456/"

# Deep sub-build investigation  
"This pipeline has nested failures, can you find the root cause? https://jenkins.company.com/job/monorepo/job/main/789/"

# Search for similar issues
"Find similar authentication failures in recent builds"

# Get specific log sections
"Show me the test failure logs from lines 2000-2500 in this build: https://jenkins.company.com/job/tests/321/"

🌐 Multi-Jenkins Support

The server automatically routes requests based on the URL:

# Production Jenkins
"Analyze: https://jenkins-prod.company.com/job/deploy/456/"

# Development Jenkins  
"Debug: https://jenkins-dev.company.com/job/feature/123/"

# EU Jenkins instance
"Check: https://jenkins-eu.company.com/job/service/789/"

🔄 URL Resolution: The MCP server matches URLs to your configured Jenkins instances and uses the appropriate credentials automatically.

📊 What You'll Get

• Failure Analysis: AI-powered root cause identification
• Sub-Build Hierarchy: Navigate complex pipeline structures
• Smart Recommendations: Actionable fixes based on your tech stack
• Relevant Log Sections: Key failure points highlighted
• Similar Issue Search: Find patterns across build history

🛠️ Advanced Features
