Model Context Protocol Servers in Quarkus/Java

What is Model Context Protocol Servers in Quarkus/Java?

This project provides multiple Model Context Protocol (MCP) servers implemented in Java using the Quarkus MCP server framework. These servers extend the capabilities of MCP‑enabled LLM AI applications, such as Claude Desktop, by allowing them to interact with databases, JVM processes, filesystems, drawing canvases, Kubernetes, containers, and web search.

How to use Model Context Protocol Servers in Quarkus/Java?

All servers are run with jbang everywhere (Java, JavaScript, Python, etc.). For example, jbang jdbc@quarkiverse/quarkus-mcp-servers runs the JDBC server. Specific server commands are provided in their respective directories.

Key features of Model Context Protocol Servers in Quarkus/Java

• Implements MCP servers in Java with Quarkus framework.
• Runs via jbang on any platform supporting Java, JavaScript, or Python.
• Includes seven ready‑to‑use servers (jdbc, jvminsight, filesystem, jfx, kubernetes, containers, wolfram).
• Supports any JDBC database (Postgres, MySQL, SQLite, etc.).
• Allows inspection of running JVM processes.
• Provides filesystem access, JavaFX drawing canvas, Kubernetes cluster interaction, container engine management, and LLM‑optimized web search.

Use cases of Model Context Protocol Servers in Quarkus/Java

• Give an LLM the ability to query and store data in any JDBC database.
• Let an LLM inspect and monitor a live JVM application.
• Enable an LLM to read and write files on a local filesystem.
• Allow an LLM to draw graphics using a JavaFX canvas.
• Have an LLM manage Kubernetes cluster resources.
• Let an LLM operate Docker/Podman/OCI containers.
• Provide LLM‑optimized web search results via Wolfram Alpha.

FAQ from Model Context Protocol Servers in Quarkus/Java

What is the Model Context Protocol (MCP)?

MCP is a protocol that allows LLM applications to extend their capabilities by connecting to servers that provide specific tools or data.

What runtime do these servers require?

They run on any system that supports Java and jbang. jbang also works with Node.js (via npx), Python (via pipx), and others.

Which MCP clients can use these servers?

Any MCP‑enabled LLM application, such as Claude Desktop. A list of clients is available at Awesome MCP Clients.

How do I run a specific server?

Use the jbang command provided in each server’s directory. For example, jbang filesystem@quarkiverse/quarkus-mcp-servers [path1] [path2] ... for the filesystem server.

How can I contribute a new server?

Clone the repository, run mvn clean install, then jbang init -t mcp <server-name> to scaffold a new server, and open a pull request.
