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/yourusername/jenkins-server-mcp.git
cd jenkins-server-mcp

2. Install dependencies:

npm install

3. Build the project:

npm run build

Configuration

The server requires the following environment variables:

• JENKINS_URL: The URL of your Jenkins server (defaults to ‘http://sohoci.rd.tp-link.net/jenkins’)
• JENKINS_USER: Jenkins username for authentication
• JENKINS_TOKEN: Jenkins API token for authentication

Configure these in your MCP settings 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"
      }
    }
  }
}

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.
