remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Integrations

Allows management of Jenkins operations including listing jobs, triggering builds with parameters, and checking build status

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
