dsh-multicad

把 AutoCAD / 中望 ZWCAD / 浩辰 GstarCAD / BricsCAD 接进 DeepSeek Harness 的 MCP 连接器插件。

内置 multiCAD-mcp，提供 7 个统一工具、覆盖 56 条 CAD 命令：画线/圆/矩形/多段线/样条/表格、图层管理、图块、实体选择与变换、导出 Excel/JSON、存 DWG/DXF/PDF。

安装

dsh plugin add dsh-multicad

装完完全退出 DSH 再打开，工具会以 mcp__multicad__* 出现。不需要单独安装 multiCAD-mcp，也不需要手动配 Python 环境。

它怎么工作

插件是一个 DSH bundle，包含四样东西：

  1. Python 源码（python/）：内置的 multiCAD-mcp 服务端；

  2. 启动器（bin/run.ps1 + bin/setup.ps1）：运行时按 %LOCALAPPDATA% 定位环境，缺了就建、坏了就修；

  3. 环境：首次启动在 %LOCALAPPDATA%\dsh-multicad\venv 建私有 venv 并装依赖（需联网，几分钟）；

  4. 挂载：cordis.patch.yml 往 DSH 里插一条 MCP 客户端记录，启动 bin/run.ps1。

所有路径都在运行时解析，跟用户名、安装位置无关。venv 被删掉后，下次启动会自动重建。

日志：

  • %LOCALAPPDATA%\dsh-multicad\plugin.log —— 插件加载与铺文件

  • %LOCALAPPDATA%\dsh-multicad\setup.log —— 环境安装

  • <项目>\logs\multicad_mcp.log —— 服务端日志

前提

  • Windows

  • 本机装了 AutoCAD 2018+、ZWCAD 2020+、GstarCAD 2020+ 或 BricsCAD 21+

  • PATH 上有 Python 3.10+（py -3 或 python 能跑）

  • CAD 必须和 DSH 用同一个 Windows 用户、同样权限级别运行

想用自己已有的 Python 环境，可不装依赖：

setx MULTICAD_PYTHON "E:\your-venv\Scripts\python.exe"

工具

mcp__multicad__* 一共 7 个：manage_session、draw_entities、manage_layers、manage_entities、manage_blocks、manage_files、export_data。

排错

现象

处理

工具没出现

看 plugin.log 和 setup.log；确认 PATH 上有 Python 3.10+

连不上 CAD

确认 CAD 已打开、非管理员运行、与 DSH 同用户

首次启动很慢

正常，正在装依赖；之后秒开
