mcp-language-server

概述

mcp-language-server 是一个 MCP 服务器，通过模型上下文协议 (MCP) 将语言服务器协议 (LSP) 功能暴露给 LLM 客户端。它使 AI 模型能够访问语义代码分析工具，包括符号定义、引用、诊断、悬停信息和重命名功能，支持 Go、Rust、Python、TypeScript 和 C++ 等多种编程语言。该实现通过 stdio 处理 LSP 通信，并将环境变量和参数传递给语言服务器。

FAQ

支持哪些语言服务器？

该服务器已测试 gopls (Go)、rust-analyzer (Rust)、pyright (Python)、typescript-language-server (TypeScript) 和 clangd (C/C++)。它应该适用于任何通过 stdio 通信的 LSP 服务器。

如何调试问题？

将 LOG_LEVEL 环境变量设置为 DEBUG，以启用所有组件的详细日志记录，包括与语言服务器的消息。
