Jenkins MCP Tool

🚀 Introduction

Jenkins MCP is an multi-Jenkins server management and automation tool developed based on the FastMCP framework, designed for DevOps processes. It supports intelligent scenario mapping, multi-server management, complete CI/CD lifecycle operations, and dynamic job creation.

✨ Core Features

🏢 Multi-Server Management

Dynamic Configuration: Supports configuration and dynamic addition/removal of multiple Jenkins servers
Environment Isolation: Supports management of multiple environments such as development, testing, and production
Secure Authentication: Supports token and environment variable-based authentication

🎯 Intelligent Scenario Mapping

Pre-configured Scenarios: Built-in common DevOps scenarios (user permission sync, app deployment, image sync)
Smart Recommendation: Automatically selects server and job path based on scenario
Personalized Guidance: Each scenario provides customized operation guidance

⚙️ Full CI/CD Support

Job Search: Supports fuzzy and exact search across multi-level directories
Parameterized Build: Automatically detects and validates required parameters
Real-time Monitoring: Build status query and log retrieval
Build Control: Supports build trigger, stop, and management
Job Creation: Create/update Jenkins jobs from Jenkinsfile with automatic directory management

🔧 Developer Friendly

MCP Standard: Complies with Model Context Protocol specification
Dockerized: Containerized deployment for easy integration
Multiple Operation Modes: Supports stdio, SSE, and HTTP transport modes

⚙️ Configuration Guide

📁 Config File Structure

Create a config.yaml file to configure Jenkins servers and application scenarios:

# Jenkins server configuration
servers:
  - name: maglev-sre           # Server alias
    uri: https://jenkins.server
    user: xhuaustc@gmail.com
    tokenEnv: JENKINS_TOKEN  # Recommended: get token from environment variable

# Pre-configured application scenarios
scenarios:
  "Sync User Permissions":
    description: "User permission sync scenario"
    server: "shlab"
    job_path: "maglev/tool/permission-replicate/"
    prompt_template: "Execute user permission sync task. Job path: {job_path}. Please confirm which users' permissions to sync?"

  "Deploy Application":
    description: "Application deployment scenario, supports diff/sync/build operations"
    server: "maglev-sre"
    job_path: "release/deploy/"
    prompt_template: "Execute application deployment task. Job path: {job_path}. Please confirm the app name, version, and environment to deploy?"

  "Sync Image to mldc":
    description: "Sync container image to mldc environment"
    server: "shlab"
    job_path: "mldc-prod/sync-container-image-to-docker-af"
    prompt_template: "Execute image sync task. Please provide the image address to sync?"

🔐 Security Configuration

Recommended: Use environment variables to manage sensitive information

export PROD_BLSM_JENKINS_TOKEN="your-production-token"
export SHLAB_JENKINS_TOKEN="your-shlab-token"

Configuration Priority:

Environment variable (variable name specified by tokenEnv)
Direct configuration (token field)
Interactive input (if neither is configured)

🚀 Quick Start

🐳 Docker Method (Recommended)

1. Build Image

cd mcps/jenkins
docker build -t jenkins-mcp .

2. Prepare Configuration

Create a config.yaml file (refer to the configuration guide above)

3. Run Container

# Use config file from current directory
docker run -i --rm \
  -v ./config.yaml:/app/config.yaml \
  -e PROD_BLSM_JENKINS_TOKEN="${PROD_BLSM_JENKINS_TOKEN}" \
  -e SHLAB_JENKINS_TOKEN="${SHLAB_JENKINS_TOKEN}" \
  jenkins-mcp

# Or specify custom config path
docker run -i --rm \
  -v /path/to/your/config.yaml:/app/config.yaml \
  -e JENKINS_TOKEN="${JENKINS_TOKEN}" \
  jenkins-mcp

🎨 MCP Client Integration

Cursor Integration

Set Environment Variables:
export JENKINS_TOKEN="your-jenkins-token"
Create Config File: Create jenkins-config.yaml in the project root:
servers: - name: your-jenkins uri: https://your-jenkins.company.com user: your-username tokenEnv: JENKINS_TOKEN scenarios: "Deploy Application": description: "Application deployment scenario" server: "your-jenkins" job_path: "deploy/"
Configure Cursor MCP Settings: Add to Cursor's MCP config:
{ "mcpServers": { "jenkins": { "command": "docker", "args": [ "run", "--rm", "-i", "-v", "/path/to/your/jenkins-config.yaml:/app/config.yaml", "-e", "JENKINS_TOKEN=${JENKINS_TOKEN}", "docker.io/mpan083/jenkins-mcp" ], "env": { "JENKINS_TOKEN": "your-jenkins-token" } } } }
Usage Example: In Cursor, ask:
"Get the list of available Jenkins scenarios" "Trigger a build for Deploy Application" "Check the status of the latest build" "Create a new test job from Jenkinsfile"

Method 2: Local Installation

Install Dependencies:
cd mcps/jenkins pip install -e .
Configure Cursor MCP Settings:
{ "mcpServers": { "command": "docker", "args": [ "run", "-i", "--rm", "-v", "~/.jenkinscliconfig:/app/config.yaml", "docker.io/mpan083/jenkins-mcp" ] } } }

Deploy Application	Application deployment, supports diff/sync/build	maglev-sre	`release/deploy/`
Sync Image to mldc	Sync container image to mldc environment	shlab	`mldc-prod/sync-container-image-to-docker-af`

🎨 Custom Scenario Configuration

📁 Scenario File Support

Jenkins MCP supports multiple ways to configure custom scenarios:

Standalone Scenario File (Recommended):
# Create custom scenario file cp scenarios.example.yaml scenarios.yaml # Specify scenario file at startup jenkins --scenarios scenarios.yaml
Environment Variable:
export JENKINS_MCP_SCENARIOS_FILE="/path/to/my-scenarios.yaml" jenkins
Configure in config.yaml:
scenarios: "Custom Deployment": description: "Custom application deployment scenario" server: "your-jenkins" job_path: "custom/deploy/" prompt_template: "Execute custom deployment task. Please confirm deployment parameters?"

🔄 Scenario Merge Rules

Default Scenarios: Load built-in scenarios from scenarios.default.yaml
User Scenarios: Load from custom scenario file
Merge Strategy: User scenarios take precedence, same-name scenarios override defaults

📝 Scenario File Example

Create a scenarios.yaml file:

scenarios:
  "Database Backup":
    description: "Execute database backup task"
    server: "production"
    job_path: "backup/database/"
    prompt_template: "Execute database backup task. Please select the database and backup type?"

  "Performance Test":
    description: "Run application performance test"
    server: "test"
    job_path: "test/performance/"
    prompt_template: "Execute performance test. Please select test scenario and load parameters?"

  # Override default scenario
  "Deploy Application":
    description: "My custom deployment process"
    server: "my-jenkins"
    job_path: "custom/deploy/"
    prompt_template: "Execute custom deployment. Please confirm deployment configuration?"

🆘 Troubleshooting

Common Issues

Q: Failed to connect to Jenkins server?
A: Check network, URL, and authentication info. Use validate_jenkins_config() to validate config.

Q: Build parameter validation failed?
A: Use get_job_parameters() to check required parameters and ensure all are provided.

Q: Docker container failed to start?
A: Check config file mount path and environment variable settings.

Q: Job creation failed with 500 error?
A: Check Jenkins permissions and CSRF settings. The tool automatically handles CSRF tokens.

Q: Cannot create job in specified folder?
A: Ensure you have permission to create folders and jobs. Jobs are automatically organized under MCPS/{username}/.

Log Debugging

# Enable detailed logs
export JENKINS_MCP_LOG_LEVEL=DEBUG
jenkins --transport stdio

Performance Optimization

Multi-level Directory Support: Efficiently handles nested Jenkins folders
Intelligent Parameter Detection: Reduces API calls through smart caching
CSRF Token Management: Automatic token handling for secure Jenkins instances
