OpenSumi 是一个开源的、高性能和高度可定制的 IDE 研发框架，它为开发者提供了一套工具和组件，用以构建双端（Web 和 Electron）的集成开发环境，着重于降低定制难度，使开发者能够轻松组合功能模块，以满足特定的业务需求。OpenSumi 的定位是让 IDE 定制化研发变得简单丝滑。

重点进展

MCP（Model Context Protocol）

近期，OpenSumi 在 3.8 版本中新增支持 MCP 协议，是国内在 MCP 官网（https://modelcontextprotocol.io/clients）首个实现 MCP 协议的 Client。

OpenSumi 目前通过 MCP 作为 Agent 的基础协议，包含如下能力：

• 内置 OpenSumi MCP Server，实现 IDE 中基本操作的各种 tools：

  • 文件操作

    • readFile：读取文件内容，支持行范围

    • editFile：改写文件，可对接 fast-apply 模型

    • listDir：列出目录内容

    • createNewFileWithText：创建带有指定内容的新文件

    • findFilesByNameSubstring：按名称搜索文件

    • getFileTextByPath：通过路径获取文件内容

    • replaceOpenEditorFile：替换当前编辑器中的内容

    • replaceOpenEditorFileByDiffPreviewer：使用差异预览替换内容

  • 编辑器

    • getCurrentFilePath：获取当前打开文件的路径

    • getSelectedText：获取当前选中的文本

    • getOpenEditorFileText：获取打开编辑器中的文本

  • 诊断

    • getDiagnosticsByPath：获取特定文件的诊断信息

    • getOpenEditorFileDiagnostics：获取打开编辑器的诊断信息

  • 终端

    • runTerminalCmd：执行命令

• 支持自定义 tools 接入，包含前端 UI 的扩展

• 支持三方 MCP Server 接入，支持 command / sse 类型的 MCP Server

• 支持自动获取 IDE 操作的上下文

• 支持任意兼容 OpenAI 模型、DeepSeek、claude 3.5 sonnet 等模型接入
