DWG MCP Server
Inspect AutoCAD DWG drawings from your agent with a read-only MCP server so you can summarize layers, entities, or metadata without opening desktop CAD for every question.
Overview
DWG MCP Server is a MCP server for the Build phase that provides read-only inspection of AutoCAD DWG files for agent-driven CAD workflows.
What is this MCP server?
- Read-only MCP access to AutoCAD DWG files for safe agent inspection
- npm package @dmytro-prototypes/dwg-mcp-server v0.1.4 with stdio transport
- DWG_MCP_HOST_FOLDERS env var limits opens to semicolon-separated absolute host paths
- Defaults toward ~/Documents when using the npm Docker launcher if folders are omitted
- Open-source GitHub repo dimitrovakulenko/dwg-mcp-server for setup and scope
- Server version 0.1.4
- npm identifier @dmytro-prototypes/dwg-mcp-server with stdio transport
- DWG_MCP_HOST_FOLDERS environment variable for allowlisted host paths
Community signal: 6 GitHub stars.
What problem does it solve?
Agents cannot interpret binary DWG files with normal text tools, so builders waste time manually opening AutoCAD for every drawing question.
Who is it for?
Indie builders shipping AEC-adjacent tools or internal agents that must quote layer or entity facts from DWGs on allowed paths.
Skip if: Teams that need write/edit CAD operations, cloud DWG hosting, or workflows with no local DWG files on the dev machine.
What do I get? / Deliverables
After you configure host folders and register the stdio server, your agent can read-only inspect DWGs and return structured drawing context in chat.
- Agent-accessible read-only DWG inspection results
- Bounded filesystem access via configured host folders only
- CAD context for downstream summarization, ticketing, or vertical features
Recommended MCP Servers
Journey fit
DWG inspection supports build-time tooling, documentation, and vertical features that reference CAD deliverables, not early idea validation. Integrations fits because the server bridges proprietary DWG binaries into MCP tools with explicit host folder allowlists rather than replacing your CAD editor.
How it compares
Read-only CAD file MCP bridge, not a full BIM platform or browser-based DWG editor.
Common Questions / FAQ
Who is DWG MCP Server for?
Developers and solo builders who need Claude or Cursor to inspect local AutoCAD DWG files read-only inside agent workflows.
When should I use DWG MCP Server?
Use it during Build when integrating CAD-aware features, support bots, or docs that require grounded answers from DWG content on disk.
How do I add DWG MCP Server to my agent?
Install @dmytro-prototypes/dwg-mcp-server, set DWG_MCP_HOST_FOLDERS to your allowed absolute paths, add the stdio MCP entry, and restart the client.
