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:

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
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
