MCP Jenkins

The Model Context Protocol (MCP) is an open-source implementation that bridges Jenkins with AI language models following Anthropic's MCP specification. This project enables secure, contextual AI interactions with Jenkins tools while maintaining data privacy and security.

Installation

Choose one of these installation methods:

# Using uv (recommended)
pip install uv

Configuration and Usage

Jetbrains Github Copilot

1. Open Jetbrains Settings
2. Navigate to Github Copilot > MCP > Configure
3. Add the following configuration:

{
  "servers": {
    "my-mcp-server": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "mcp-jenkins",
        "--jenkins-url=xxx",
        "--jenkins-username=xxx",
        "--jenkins-password=xxx"
      ]
    }
  }
}

VSCode Copilot Chat

1. Create .vscode folder with mcp.json file in you workspace for local setup or edit settings.json trough settings menu.
2. Insert the following configuration:

• SSE mode

{
    "servers": {
        "jenkins": {
            "url": "http://localhost:9887/sse",
            "type": "sse"
        }
    }
}

• Streamable-Http mode

{
    "servers": {
        "mcp-jenkins-mcp": {
            "autoApprove": [],
            "disabled": false,
            "timeout": 60,
            "type": "streamableHttp",
            "url": "http://localhost:9887/mcp"
        }
    }
}

Run the Jenkins MCP server with the following command:

uvx mcp-jenkins \
  --jenkins-url xxx \
  --jenkins-username xxx  \
  --jenkins-password xxx \
  --transport sse

Health Check Endpoint

When running with --transport streamable-http or --transport sse, the server exposes a plain HTTP liveness endpoint:

GET /healthz  ->  200 OK

It always returns 200 and bypasses the x-jenkins-* auth headers, so it is safe to use directly as a Kubernetes liveness/readiness probe without any Jenkins credentials. Example probe:

livenessProbe:
  httpGet:
    path: /healthz
    port: 9887
  initialDelaySeconds: 5
  periodSeconds: 10

Note: this is a liveness check only — it does not verify connectivity to the upstream Jenkins server.
