DWG MCP Server
Gives Claude read-only access to AutoCAD DWG files through LibreDWG. Each opened file spawns a dedicated Rust worker that builds an in-memory index of objects, handles, types, blocks, layouts, and spaces, then answers queries against that index instead of rescanning the file. You get eight tools: list accessible folders, open and close files, enumerate types globally or per-document, describe type schemas, fetch objects by handle, and run filtered queries with scope traversal, sorting, and pagination. The query engine supports filters on type, block membership, layout, model versus paper space, and property values. Ships as a Python stdio server that launches a Docker container with a prebuilt static worker binary. Useful when you need an AI agent to inspect drawing structure, search for entities, or navigate block and layer hierarchies without manual parsing.

Readme
DWG MCP Server
DWG and DXF file format access for AI via MCP.
Connect DWG and DXF files to Claude, ChatGPT, Codex, Cursor, and other MCP clients. DWG MCP Server provides structured access to DWG data so AI can understand and reason about drawings. Source files remain read-only; supported entity properties can be changed in memory for inspection and rendering.
Quick Start
Use DWG MCP Server from the MCP client of your choice. The npm package downloads the matching native build from GitHub Releases on first use, verifies its SHA-256 checksum, caches it, and runs it directly. Docker and a separate Python installation are not required.
Native installers
macOS Apple Silicon:
curl -fsSL https://raw.githubusercontent.com/dimitrovakulenko/dwg-mcp-server/main/scripts/install.sh | sh
Windows x64 (PowerShell):
irm https://raw.githubusercontent.com/dimitrovakulenko/dwg-mcp-server/main/scripts/install.ps1 | iex
Both installers download the latest native release and verify its SHA-256 checksum before installation.
