- 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)
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
JBang MCP ExamplesCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
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.
