Overview

What is Langchain4j APP MCP HOST/Client For Spring boot MCP server?

It is a Java-based MCP (Model Context Protocol) client/host built with Langchain4j, designed to connect to Spring Boot MCP servers. The server demonstrates integration with private LLMs like Ollama (Qwen2.5-coder:14b) and supports both SSE and STDIO transport modes. It is intended for developers building AI assistants that leverage MCP tools.

How to use Langchain4j APP MCP HOST/Client For Spring boot MCP server?

The project provides branches with step‑by‑step examples. The final branch (03‑use‑mcp‑server‑stadio) shows the complete setup. You run an MCP server demo image in podman in either SSE or STDIO mode, obtain the server URL (SSE) or STDIO transport, then create a ChatLanguageModel for Ollama, an MCP Transport, an MCP Client, a ToolProvider to fetch tools from the server, and finally an AI services instance (Bot) to call the assistant with a tool.
