Quarkus Agent

Quarkus Agent MCP

<p align="center"> <img src="logo.png" width="250" alt="Quarkus Agent MCP Logo"> </p>

A standalone MCP server that enables AI coding agents to create, manage, and interact with Quarkus applications. It runs as a separate process that survives app crashes, giving agents the ability to create projects, check for updates, read extension skills, control application lifecycle, proxy Dev MCP tools, and search Quarkus documentation.

Part of the DevStar working group.

Prerequisites

• Java 21+
• Docker or Podman (for documentation search)
• One of: Quarkus CLI, Maven, or JBang (for creating new projects)

Installation

Claude Code plugin

Add the marketplace and install the plugin:

claude plugin marketplace add quarkusio/quarkus-agent-mcp
claude plugin install quarkus-agent@quarkus-tools

This installs the plugin and configures the MCP server automatically. Requires JBang.

Via JBang (recommended)

JBang resolves the uber-jar from Maven Central automatically — no build step needed.

Claude Code

claude mcp add -s user quarkus-agent -- jbang quarkus-agent-mcp@quarkusio

VS Code / GitHub Copilot

Add to .vscode/mcp.json in your workspace:

{
  "servers": {
    "quarkus-agent": {
      "type": "stdio",
      "command": "jbang",
      "args": ["quarkus-agent-mcp@quarkusio"]
    }
  }
}

IBM Bob

Add to .bob/mcp.json:

{
  "mcpServers": {
    "quarkus-agent": {
      "command": "${env:JBANG_HOME}/bin/jbang",
      "args": [
        "quarkus-agent-mcp@quarkusio"
      ],
      "env": {
        "JAVA_HOME": "${env:JAVA_HOME}"
      },
      "disabled": false
    }
  }
}

Why absolute paths? Bob inherits system PATH, not your shell PATH. See Troubleshooting below.

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "quarkus-agent": {
      "command": "jbang",
      "args": ["quarkus-agent-mcp@quarkusio"]
    }
  }
}
