A collection of Quarkus-based Model Context Protocol servers offering diverse capabilities, including database interaction, JVM introspection, file system access, and container management.
The safety of these servers varies greatly depending on the specific server being used. Read-only servers like jvminsight pose minimal risk. Servers that interact with infrastructure, like kubernetes or containers, require careful configuration and monitoring to prevent unintended consequences. Ensure proper access controls are in place to mitigate risks.
Performance depends on the specific server and the resources it accesses. Consider optimizing database queries, file system access, and network communication to improve performance.
Cost depends on the resources used by the servers, such as database storage, API calls to Wolfram Alpha, and cloud infrastructure. Monitor resource usage to control costs.
npx @jbangdev/jbangjdbcStores and retrieves data from a database using a JDBC URL.
Can perform arbitrary database operations, including data modification and deletion, depending on the provided JDBC URL and credentials.
jvminsightInspects a running JVM process.
Primarily read-only, providing insights into JVM internals without modifying state.
filesystemServes files from a file system.
Exposure of files can lead to information disclosure; write access depends on file system permissions.
jfxExposes a canvas for drawing using JavaFX.
Potential for code execution if the JavaFX canvas is used to render untrusted content.
kubernetesInteracts with a Kubernetes cluster.
Can perform any action allowed by the configured Kubernetes credentials, including deploying, modifying, and deleting resources.
containersWorks with Docker/Podman/OCI compatible container engines.
Can manage containers, potentially leading to resource exhaustion or security breaches if not properly controlled.
wolframPerforms web search optimized for use by a large language model through the Wolfram Alpha LLM API.
Limited to web search via the Wolfram Alpha API; no direct access to system resources.

The safety of these servers varies greatly depending on the specific server being used. Read-only servers like `jvminsight` pose minimal risk. Servers that interact with infrastructure, like `kubernetes` or `containers`, require careful configuration and monitoring to prevent unintended consequences. Ensure proper access controls are in place to mitigate risks.
Autonomy depends entirely on the specific server and its configuration. Exercise caution when granting access to servers with write or execute capabilities.
Production Tip
Implement robust access controls and monitoring to protect sensitive resources and detect potential security breaches.
Currently, most servers do not implement authentication by default. It is crucial to implement your own authentication and authorization mechanisms.
Use role-based access control (RBAC) in Kubernetes to limit the permissions granted to the server's service account. Avoid granting cluster-admin privileges.
Yes, but you must carefully configure and monitor them to ensure security and stability. Implement proper access controls, logging, and error handling.
Follow the instructions in the Contributing section of the README.md file. Make sure to include a clear description of the server's functionality and potential risks.
No, these servers are not sandboxed by default. You must implement your own sandboxing mechanisms if required.
Use standard Java monitoring tools, such as JConsole or VisualVM, to monitor the JVM's performance. You can also add custom logging and metrics to track server activity.
Check the README.md file for each server. You can also find examples in the project's test suite.
