About im-mcp

im-mcp (本地绿泡泡 & DuangDuang AI 检索 MCP Server)

基于 Model Context Protocol (MCP) 规范构建的本地 IM(绿泡泡 & DuangDuang)聊天记录与通讯录检索服务。 极简、只读、完全离线本地运行,让 Claude Desktop、Cursor、Cline、Pi 等 AI Agent 能够安全、高速地检索与总结你的工作沟通、群聊记录和知识库。

注:原底层参考项目以 Git Submodule 形式统一归档在 reference/ 目录下(reference/wechat-local-viewer 与 reference/dingwave-V3)。

- ⚡ 超低延迟:直接基于本地解密 SQLite 数据库,毫秒级响应。 - 🔒 纯本地与只读:所有数据均在本地,绝不上云;以只读方式运行,不破坏原始数据。 - 📦 按需安装(Optional Dependencies):一个仓库,两套独立入口;支持只装绿泡泡、只装DuangDuang或全量安装。 - 💬 丰富格式解析: - 绿泡泡:支持普通文本、引用消息、富文本卡片、小程序、传输文件(PDF/Excel/Word等)。 - DuangDuang:支持多表分片聚合(tbmsg000~tbmsg127)、联系人实名映射、Markdown卡片、协同日程通知、文件附件提取。
