mcp-agent-java is a Java example agent that demonstrates using the Model Context Protocol (MCP) to let LLM-based agents discover and call external tools at runtime. It targets Java developers building AI agents or Spring Boot services that need structured, typed access to external services (databases, APIs, internal tools). Key points: - Implements the full agent loop: receive query → send LLM available tools → LLM returns answer or tool call → execute tool → synthesize result. - Two integration paths: Spring AI (auto-wired MCP tools, recommended for Spring Boot) and LangChain4j (manual McpToolProvider for more control). - Shows dependencies, config examples, a REST /ask endpoint, SSE/streaming support, and architecture connecting to a lazarus-mcp server and Lazarus DB. - MIT licensed.
