Jenkins MCP Server

An MCP server for interacting with a Jenkins server. Allows you to trigger jobs, check build statuses, and manage your Jenkins instance through MCP.

Installation

Add the following to your MCP client configuration file.

  "mcpServers": {
    "ashwinighuge3012-jenkins-mcp-server": {
      "command": "jenkins-mcp",
      "args": [],
      "env": {
        "JENKINS_URL": "http://your-jenkins-server:8080",

    }
  }
}

You deploy and run a production-ready MCP server to manage Jenkins CI/CD workflows through a programmable API. This server lets AI assistants and automation tools trigger jobs, monitor builds, fetch logs, manage artifacts, and perform advanced queries against your Jenkins instance in a scalable, secure way.

How to use

You run the MCP server locally or in your environment and connect your MCP client to it. Use the provided tools to trigger jobs, check build statuses, stream console logs, manage artifacts, and monitor queues. If you enable HTTP transport, you can expose the MCP API over HTTP for integration with gateways or webhooks. The server handles authentication, validation, and retries to ensure reliable interactions with Jenkins.

How to install

Prerequisites: Node.js 14.0.0 or higher, Python 3.12 or higher, and Jenkins 2.401+ with an API token.

# Global installation (recommended)
npm install -g @ashwinighuge/jenkins-mcp-server

# Or use directly with npx
npx @ashwinighuge/jenkins-mcp-server --help

Configuration and start guidance

Configure access to Jenkins by setting the required environment variables when you start the server. The MCP server reads Jenkins connection details from these variables and uses them to authenticate and interact with Jenkins.

      "env": {

      }
    }

Using the server with an MCP client

You can operate the Jenkins MCP server from an MCP client to perform a wide range of actions. The server exposes a set of endpoints for job control, status retrieval, artifact management, batch operations, caching controls, and more. Use the client to call these endpoints in your automation scripts, chat assistants, or workflow orchestrators.

Additional setup notes

When running in STDIO mode, you interact with the server via standard input/output, which is ideal for local desktop integrations. In HTTP mode, you expose the MCP API over a port and can integrate with MCP Gateways or web services.

Troubleshooting

If you encounter connection issues to Jenkins, verify the URL, the API token’s validity, and your network access. For 2FA or CSRF challenges, prefer using API tokens and ensure the MCP server handles CSRF protection automatically.

Enable verbose logging during setup to diagnose issues: set DEBUG=jenkins-mcp and run the server to view detailed output.

Notes on usage patterns

Trigger a job with parameters and monitor its progress
Query for jobs with filtering by status, date, or last result
Stream or fetch console logs for in-progress or completed builds
List and download artifacts across builds
Run multiple jobs in parallel with priority controls
Inspect queue status and manage waiting builds
Cache frequently accessed data to improve response times
Handle retry logic with exponential backoff for reliability
