Jenkins MCP

MCP server for managing Jenkins operations.

Installation

Installing via Smithery

To install Jenkins MCP for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @kjozsa/jenkins-mcp --client claude

Installing Manually

uvx install jenkins-mcp

Configuration

Add the MCP server using the following JSON configuration snippet:

{ "mcpServers": { "jenkins-mcp": { "command": "uvx", "args": ["jenkins-mcp"], "env": { "JENKINS_URL": "https://your-jenkins-server/", "JENKINS_USERNAME": "your-username", "JENKINS_PASSWORD": "your-password", "JENKINS_USE_API_TOKEN": "false" } } } }

CSRF Crumb Handling

Jenkins implements CSRF protection using "crumbs" - tokens that must be included with POST requests. This MCP server handles CSRF crumbs in two ways:

  1. Default Mode: Automatically fetches and includes CSRF crumbs with build requests
    • Uses session cookies to maintain the web session
    • Handles all the CSRF protection behind the scenes
  2. API Token Mode: Uses Jenkins API tokens which are exempt from CSRF protection
    • Set JENKINS_USE_API_TOKEN=true
    • Set JENKINS_PASSWORD to your API token instead of password
    • Works with Jenkins 2.96+ which doesn't require crumbs for API token auth

You can generate an API token in Jenkins at: User → Configure → API Token → Add new Token

Features

  • List Jenkins jobs
  • Trigger builds with optional parameters
  • Check build status
  • CSRF crumb handling for secure API access

Development
