Jenkins Server MCP

A Model Context Protocol (MCP) server that provides tools for interacting with Jenkins CI/CD servers. This server enables AI assistants to check build statuses, trigger builds, and retrieve build logs through a standardized interface.

Installation

1. Clone this repository:

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

1. Install dependencies:

npm install

1. Build the project:

npm run build

Configuration

The server requires the following environment variables:

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

Configure these in your MCP settings file:

For Claude Desktop

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

{ "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" } } } }

Tools and Usage

1. Get Build Status

Get the status of a Jenkins build:

// Example 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" }

2. Trigger Build

Trigger a new Jenkins build with parameters:

// Example 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 } }

3. Get Build Log

Retrieve the console output of a Jenkins build:

// Example 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" }

Development

For development with auto-rebuild:

npm run watch

Debugging

Since MCP servers communicate over stdio, you can use the MCP Inspector for debugging:

npm run inspector

This will provide a URL to access debugging tools in your browser.
