Connect LLMs to databases, containers, and JVM processes

Quarkus MCP Servers is a collection of Model Context Protocol servers implemented in Java on the Quarkus MCP server framework, each runnable standalone via jbang without a separate install step. jdbc stores and retrieves data from any JDBC-compatible database - Postgres, MySQL, Oracle, SQLite, and others - given just a JDBC URL. jvminsight inspects a running JVM process. filesystem serves files from one or more given filesystem paths. jfx exposes a canvas for making drawings with JavaFX. kubernetes interacts with a Kubernetes cluster. containers works with Docker, Podman, or other OCI-compatible container engines. wolfram performs LLM-optimized web search through the Wolfram Alpha LLM API. A related project, WildFly MCP, lets an AI client interact with running WildFly application servers.

Use these servers individually, picking the one matching the task: querying a database over JDBC, inspecting a live JVM, serving local files, drawing with JavaFX, managing Kubernetes resources, working with containers, or running Wolfram Alpha-powered computation and search. Each server is launched separately with its own jbang command targeting that server's coordinate on quarkiverse/quarkus-mcp-servers; there is no single combined server that exposes all seven at once. jbang itself can be run through several wrappers (npx @jbangdev/jbang, uvx jbang, pipx jbang) depending on the ecosystem already in use.

Each server is launched with a one-line jbang command, for example jbang jdbc@quarkiverse/quarkus-mcp-servers for the JDBC server or jbang filesystem@quarkiverse/quarkus-mcp-servers [path1] [path2] ... for the filesystem server, which accepts one or more paths to serve. The project welcomes new servers: contributors can scaffold one with jbang init -t mcp <name> after cloning and building the repository with Maven, then wire the new module into the root pom.xml. Ideas already noted for future servers include Zulip, JFR/JMX-based Java flight recording, and Quarkus dev-mode integration.

Run any server directly with jbang, no separate installation required:

jbang jdbc@quarkiverse/quarkus-mcp-servers

Substitute the server name - jvminsight, filesystem, jfx, kubernetes, containers, or wolfram - for jdbc as needed; jbang can be invoked via npx @jbangdev/jbang, uvx jbang, or pipx jbang if jbang itself is not already installed. Each server works with Claude Desktop or any other MCP-enabled client.

Java and Quarkus developers who want ready-made MCP servers for common infrastructure tasks - databases, JVM diagnostics, files, Kubernetes, containers, and Wolfram Alpha - runnable with a single jbang command, and who may want to contribute new ones.
