Unified MCP server for AutoCAD — File IPC, COM (multi-CAD), and headless DXF backends. 22 tools, ~130+ operations. Apache 2.0.
概览
A unified MCP (Model Context Protocol) server for AutoCAD that combines three backend strategies into a single, extensible package. Set the backend via environment variable: For AutoCAD LT, load the LISP dispatcher: 1. Open AutoCAD LT 2. In the command line, type: (load "/path/to/autocad-mcp/lisp-code/mcp_dispatch.lsp") 3. The MCP server will automatically detect the running AutoCAD instance - Python 3.10+ - mcp[cli] -- MCP protocol framework - ezdxf -- DXF read/write - matplotlib + Pillow -- Screenshot rendering - structlog -- Structured logging - pywin32 -- Windows COM + Win32 API (Windows only) - openpyxl -- Excel export Built by combining the best of: - puran-water/autocad-mcp -- Dual backend architecture, File IPC, execute_lisp - ngk0/autocad-mcp -- 19 tool categories, xref/layout/electrical, 232 tests - AnCode666/multiCAD-mcp -- COM multi-CAD support, batch operations, NLP, Excel export Licensed under the Apache License, Version 2.0.
