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
