mcpls

概述

mcpls 是 AI 编程助手与语言服务器之间的通用桥接器。它通过模型上下文协议（MCP）展示了 LSP 的全部功能，包括类型推断、交叉引用分析和语义导航，使 AI 代理能够像 IDE 那样理解代码。该工具为 AI 代理提供类型信息、交叉引用、语义导航、实时诊断和安全重构能力。

  试试:What methods are available on this object?试试:Complete this function call
• get_document_symbols

  Structured outline — functions, types, constants, imports
