langchain4j-mcp-server-patterns

Standardized MCP server implementation patterns with LangChain4j for extending AI capabilities. Use this skill to design and implement Model Context Protocol (MCP) integrations with LangChain4j. The main concerns are: Keep SKILL.md focused on the implementation flow. Use the bundled references for expanded examples and API-level detail. Use this skill when: Typical trigger phrases include langchain4j mcp , java mcp server , mcp tool provider , spring boot mcp , and connect langchain4j to mcp . Decide what the server should expose: Keep names stable, descriptions concrete, and schemas small enough for a client or model to understand quickly. Use separate classes for each concern: Validate arguments before execution and return clear error messages for invalid input or unavailable dependencies. Use: Pin external server versions and document how the process is started, authenticated, and monitored.
