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.

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 -q jdbc@quarkiverse/quarkus-mcp-servers

See more in the jdbc readme.

filesystem

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

jbang -q 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 -q 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 -q kubernetes@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](https://github.com/wildfly-extras/wildfly-mcp/blob/main/wildfly-mcp-server/README.md).

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 -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 jfr 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 :)
