What is Quarkus-mcp-servers?

Quarkus-mcp-servers is a project that hosts various Model Context Protocol (MCP) servers built with Java and the Quarkus MCP server framework. These servers are designed to enhance the functionality of Large Language Model (LLM) AI applications that are MCP-enabled, such as Claude Desktop.

How to use Quarkus-mcp-servers?

The servers within this project can be easily run using jbang everywhere, which supports Java, JavaScript, Python, and more. You can replace jbang with npx @jbangdev/jbang, uvx jbang, or pipx jbang depending on your preferred environment. Each server has a specific command to run it, for example, jbang jdbc@quarkiverse/quarkus-mcp-servers for the JDBC server.

To contribute a new server, you can clone the repository, build it with mvn clean install, and then use jbang init -t mcp [server-name] to generate a new server directory. After adding your content and updating the README.md, you can add the new module to the root pom.xml and open a pull request.

Key Features of Quarkus-mcp-servers

• Extensible LLM Capabilities: Extends the functionality of MCP-enabled LLM AI applications.
• Multiple Server Types: Offers a variety of servers for different functionalities, including:
  • JDBC: Connects to and interacts with any JDBC-compatible database (MySQL, PostgreSQL, Oracle, SQL Server, SQLite, etc.).
  • JVMInsight: Inspects running JVM processes.
  • Filesystem: Serves files from a file system.
  • JFX: Exposes a JavaFX canvas for drawing.
  • Kubernetes: Interacts with Kubernetes clusters.
  • Containers: Works with Docker, Podman, and OCI-compatible container engines.
  • Wolfram: Performs web searches optimized for LLMs via the Wolfram Alpha LLM API.
• Easy Deployment: Servers can be run with jbang everywhere for cross-platform compatibility.
• Community Contributions: Encourages and provides a clear process for contributing new server ideas and implementations.

Use Cases of Quarkus-mcp-servers

• Database Interaction for LLMs: An LLM application can use the JDBC server to query, insert, update, and delete data from various databases.
• JVM Monitoring: Developers can use the JVMInsight server to monitor and inspect running Java applications through their LLM.
• File System Access: LLMs can interact with local file systems using the Filesystem server to retrieve or manage files.
• Graphical Output: The JFX server allows LLMs to generate visual outputs or drawings.
• Container and Kubernetes Management: LLMs can manage and interact with Docker containers and Kubernetes clusters.
• Enhanced Web Search: The Wolfram server enables LLMs to perform advanced, optimized web searches.

FAQ from Quarkus-mcp-servers

Q: What is MCP? A: MCP stands for Model Context Protocol, which is a protocol designed to extend the capabilities of LLM AI applications.

Q: How can I run these servers? A: You can run these servers using jbang everywhere. Simply use the command jbang [server-name]@quarkiverse/quarkus-mcp-servers for the desired server.

Q: Can I contribute my own server? A: Yes, the project encourages contributions. You can follow the steps outlined in the "Contributing" section of the README to develop and submit your own MCP server.

Model Context Protocol Servers in Quarkus/Java

This project contains Model Context Protocol servers, implemented in Java using the Quarkus MCP server framework.

These lets you extend the capabilities of your MCP enabled LLM (Large Language Model) AI applications.

These also work in MCP enabled LLM applications, like Claude Desktop. You can find other clients on Awesome MCP Clients page.

Running the servers

All of these servers are available to run with jbang everywhere: Java, JavaScript, Python and more. Where it says jbang it can be replaced with npx @jbangdev/jbang or uvx jbang or pipx jbang dependent on your preference.

Servers

jdbc

The jdbc server can be used to store and retrieve data from a database given just a JDBC URL. You can use any JDBC database, like Postgres, MySQL, Oracle, Sqlite, etc.

jbang jdbc@quarkiverse/quarkus-mcp-servers

See more in the jdbc readme.

jvminsight

The jvminsight server is a server that can be used to inspect a running JVM process.

jbang jvminsight@quarkiverse/quarkus-mcp-servers

See more in the jvminsight readme.

filesystem

The filesystem server is a file system server that can be used to serve files from a file system.

jbang filesystem@quarkiverse/quarkus-mcp-servers [path1] [path2] ...

See more in the filesystem readme.

jfx

The jfx server exposes a canvas that can be used to make drawings using JavaFX.

jbang jfx@quarkiverse/quarkus-mcp-servers

See more in the jfx readme.

kubernetes

The kubernetes server can be used to interact with a Kubernetes cluster.

jbang kubernetes@quarkiverse/quarkus-mcp-servers

containers

The 'containers' server lets you work with Docker/Podman/OCI compatible container engines.

jbang containers@quarkiverse/quarkus-mcp-servers

wolfram

The wolfram server can be used to perform web search optimized for use by a large language model through the Wolfram Alpha LLM API.

jbang wolfram@quarkiverse/quarkus-mcp-servers

Other Quarkus MCP based servers

WildFly

A WildFly MCP server that allows you to interact with WildFly running servers.

You can check this WildFly vlog that demonstrates its capabilities.

Read more in the WildFly MCP Server readme.

Ideas for other servers

If you have ideas for other servers, feel free to contribute them to this project.

If missing ideas, then look at the reference servers at https://github.com/modelcontextprotocol/servers and see if you can implement them in this project.

Other ideas:

• zulip
• jfr/java hooked to jmx/jfr
• quarkus dev mode
• ...

Contributing

If you have ideas for other servers, feel free to contribute them to this project.

To get started, clone the repository and build it:

git clone https://github.com/quarkiverse/quarkus-mcp-servers
cd quarkus-mcp-servers
mvn clean install

Then run the following command to generate a new server for i.e. jfr:

mkdir jfr
cd jfr
jbang init -t mcp jfr

This will create the jfr directory with a Hello World MCP server.

You can then build it:

mvn clean install

To wire it into the full project you need to add <module>jfr</module> to the root pom.xml file.

Make sure you have added some useful content to the README.md file + updated the demo image.

Then open a PR :)
