What is research?
This project is a demonstration of building an agentic application using Quarkus, LangChain4j, and the Model Context Protocol. It leverages Quarkus' supersonic subatomic Java framework and LangChain4j's capabilities for interacting with language models. It uses multiple MCP servers such as Brave web search, OpenAI, Google Maps, and Slack to enable agent functionalities.
How to use research?
To use this application, you need to install Node, NPM and either Podman or Docker. Clone the repository, configure the required API keys in a .env file, and run the application in dev mode using ./mvnw compile quarkus:dev. You can also package the application using ./mvnw package for runnable jar and create native executable using ./mvnw package -Dnative. Access the application through http://localhost:8080 to interact after either running jar or native executable.
