stephanj/LSP4J-MCP
A Java MCP (Model Context Protocol) server that wraps JDTLS (Eclipse JDT Language Server) using LSP4J to provide Java IDE features to AI assistants like Claude.
Exposes five Java code intelligence tools (symbol search, references, definitions, document structure, interface discovery) by bridging JDTLS through LSP4J's JSON-RPC stdio transport into the MCP protocol. The server spawns JDTLS as a subprocess and routes AI assistant queries through JavaTools, enabling semantic code navigation without reimplementing language analysis. Integrates directly with Claude Code via `.mcp.json` configuration and supports any Java project workspace.
