Jenkins MCP server

The Jenkins Server MCP provides a Model Context Protocol server that enables AI assistants to interact with Jenkins CI/CD servers. It allows checking build statuses, triggering builds, and retrieving build logs through a standardized interface, making it easier to integrate Jenkins operations into AI workflows.

Installation

To install the Jenkins Server MCP:

1. Clone the repository and navigate to the project directory:

   git clone https://github.com/hekmon8/jenkins-server-mcp.git
   cd jenkins-server-mcp
   

2. Install the required dependencies:

   npm install
   

3. Build the project:

   npm run build
   

Configuration

The server requires the following environment variables for proper operation:

• JENKINS_URL: URL of your Jenkins server
• JENKINS_USER: Jenkins username for authentication
• JENKINS_TOKEN: Jenkins API token for authentication

Claude Desktop Configuration

You'll need to add the MCP server to your Claude Desktop configuration file:

MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%/Claude/claude_desktop_config.json

Add the following configuration:

{
  "mcpServers": {
    "jenkins-server": {
      "command": "node",
      "args": ["/path/to/jenkins-server-mcp/build/index.js"],
      "env": {
        "JENKINS_URL": "https://your-jenkins-server.com",
        "JENKINS_USER": "your-username",
        "JENKINS_TOKEN": "your-api-token"
      }
    }
  }
}

Available Tools

Get Build Status

Retrieves the status of a Jenkins build.

Usage:

const result = await mcpClient.useTool("jenkins-server", "get_build_status", {
  jobPath: "view/xxx_debug",
  buildNumber: "lastBuild"  // Optional, defaults to lastBuild
});

Input Schema:

{
  "jobPath": "string",  // Path to Jenkins job
  "buildNumber": "string"  // Optional, build number or "lastBuild"
}

Trigger Build

Initiates a new Jenkins build with optional parameters.

Usage:

const result = await mcpClient.useTool("jenkins-server", "trigger_build", {
  jobPath: "view/xxx_debug",
  parameters: {
    BRANCH: "main",
    BUILD_TYPE: "debug"
  }
});

Input Schema:

{
  "jobPath": "string",  // Path to Jenkins job
  "parameters": {
    // Build parameters as key-value pairs
  }
}

Get Build Log

Retrieves the console output from a Jenkins build.

Usage:

const result = await mcpClient.useTool("jenkins-server", "get_build_log", {
  jobPath: "view/xxx_debug",
  buildNumber: "lastBuild"
});

Input Schema:

{
  "jobPath": "string",  // Path to Jenkins job
  "buildNumber": "string"  // Build number or "lastBuild"
}

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "jenkins-server" '{"command":"node","args":["/path/to/jenkins-server-mcp/build/index.js"],"env":{"JENKINS_URL":"https://your-jenkins-server.com","JENKINS_USER":"your-username","JENKINS_TOKEN":"your-api-token"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "jenkins-server": {
            "command": "node",
            "args": [
                "/path/to/jenkins-server-mcp/build/index.js"
            ],
            "env": {
                "JENKINS_URL": "https://your-jenkins-server.com",
                "JENKINS_USER": "your-username",
                "JENKINS_TOKEN": "your-api-token"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "jenkins-server": {
            "command": "node",
            "args": [
                "/path/to/jenkins-server-mcp/build/index.js"
            ],
            "env": {
                "JENKINS_URL": "https://your-jenkins-server.com",
                "JENKINS_USER": "your-username",
                "JENKINS_TOKEN": "your-api-token"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
