What is JBang MCP Examples?

JBang MCP Examples is a collection of example MCP servers implemented in Java using JBang, enabling zero‑install execution. It provides ready‑to‑run servers such as a calculator, real‑weather, and stopwatch, aimed at developers exploring the Model Context Protocol.

How to use JBang MCP Examples?

Run the servers directly with jbang commands, e.g., jbang ./src/main/java/MCPCalculator.java or using shorthand jbang mcp-calculator@jabrena. Build and run Docker images with docker build and docker run. Use docker compose up to start multiple services, and view the web UI at http://localhost:3000/. An example AI application (AIApp.java) is also included.

Key features of JBang MCP Examples

  • Multiple example MCP servers: Calculator, RealWeather, StopWatch
  • Zero‑install Java execution via JBang
  • Docker and Docker Compose support for containerized deployment
  • Includes a sample AI application integrating with MCP
  • Shorthand JBang aliases (mcp-calculator@jabrena, mcp-realweather@jabrena)

Use cases of JBang MCP Examples

  • Running a calculator MCP server for demonstration or testing
  • Fetching real‑world weather data through an MCP server
  • Using a stopwatch MCP server for timing operations
  • Deploying MCP servers in Docker containers for production‑like setups
  • Building an AI‑powered Java application that consumes MCP tools

常见问题

1

What example servers are included?

The repository includes MCPCalculator, MCPRealWeather, and MCPStopWatch servers, each implemented in Java.

2

How do I run the servers?

Use `jbang ./src/main/java/MCPCalculator.java` (or the other Java files) or the shorthand `jbang mcp-calculator@jabrena`. For Docker, use `docker build` and `docker run` or `docker compose up`.

3

Do I need to install anything to use JBang MCP Examples?

You need a Java SDK (SDKMAN is shown with `sdk env`) and JBang installed. Maven (via `./mvnw`) is used for building and verifying.

4

Can I run the servers in a container?

Yes. A Dockerfile is provided for MCPStopWatch, and a `docker-compose.yml` launches all servers. The web UI runs on port 3000.

5

Where can I find more MCP servers and references?

The README links to a Quarkus MCP JDBC server, the awesome‑mcp‑servers list, the JBang GitHub action, and a Discord channel for MCP discussions.
