## What it does

This plugin launches a standalone MCP server that runs in a distinct process. Because it stays isolated, it survives unexpected crashes in your target application. Coding agents can generate project layouts, inspect extension skills, direct application lifecycles, and forward Dev MCP calls.

Documentation lookup relies on `quarkus_searchDocs`, which requires an active Docker or Podman engine. Scaffolding works via Quarkus CLI or Maven, and your environment must run Java 21+. Without Java 21, the server will fail to launch.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin install quarkus-agent@claude-plugins-official
```
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install quarkus-agent@claude-community
```
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-official
```

## When to use it
- Scaffold a Quarkus project from scratch
- Query official Quarkus documentation directly through the agent
- Maintain active MCP sessions when the target app crashes
- Proxy dev tools and inspect extension skills

## Example prompts
- Create a new Quarkus service with Maven and a REST endpoint
- Search the Quarkus docs for how to configure a reactive client
- Check for extension updates in the current Quarkus project

# Quarkus Agent MCP

[![MCP Toplist](https://mcptoplist.com/badge/pulsemcp%2Fquarkus-agent-mcp.svg)](https://mcptoplist.com/server/pulsemcp%2Fquarkus-agent-mcp)

</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](https://github.com/quarkusio/quarkus/discussions/53093) working group.

## Prerequisites

- Java 21+
- Docker or Podman (for documentation search)
- One of: [Quarkus CLI](https://quarkus.io/guides/cli-tooling), [Maven](https://maven.apache.org), or [JBang](https://www.jbang.dev/download/) (for creating new projects)

## Installation

### Claude Code plugin

Add the marketplace and install the plugin:

```bash
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](https://www.jbang.dev/download/).

### Via JBang (recommended)

[JBang](https://www.jbang.dev/download/) resolves the uber-jar from Maven Central automatically — no build step needed.

#### Claude Code

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

#### VS Code / GitHub Copilot

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

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

#### IBM Bob

Add to `.bob/mcp.json`:

```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](#jbang-or-java-not-found-enoent) below.

#### Cursor

Add to `.cursor/mcp.json`:

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

#### Windsurf

Add to `~/.codeium/windsurf/mcp_config.json`:

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

#### JetBrains IDEs (IntelliJ IDEA, WebStorm, etc.)

In **Settings → Tools → AI Assistant → MCP Servers** (or the GitHub Copilot MCP settings), add a server with an **absolute path** to `jbang`:

```json
{
  "mcpServers": {
    "quarkus-agent": {
      "type": "stdio",
      "command": "/home/you/.jbang/bin/jbang",
      "args": ["quarkus-agent-mcp@quarkusio"]
    }
  }
}
```

> **Why absolute paths?** JetBrains IDEs launched from the desktop inherit the **system PATH**, not your shell PATH (`~/.bashrc` / `~/.zshrc`). Tools installed via SDKMAN!, JBang's default installer, asdf, or mise are typically on the shell PATH only — so the IDE can't find them. See [Troubleshooting](#jbang-or-java-not-found-enoent) below.

Alternatively, use the direct download method with an absolute path to `java`:

```json
{
  "mcpServers": {
    "quarkus-agent": {
      "type": "stdio",
      "command": "/path/to/java",
      "args": ["-jar", "/path/to/quarkus-agent-mcp-runner.jar"]
    }
  }
}
```

### Via direct download

Download the uber-jar from the [latest GitHub Release](https://github.com/quarkusio/quarkus-agent-mcp/releases/latest), then:

```bash
claude mcp add -s user quarkus-agent -- java -jar /path/to/quarkus-agent-mcp-runner.jar
```
