Civil 3D MCP · for Autodesk Civil 3D · coming soon

Let AI read your Civil 3D drawings.

Civil 3D MCP is an MCP server for AI assistants such as Claude, Codex and Cursor to read the Civil 3D drawing open on your PC — surfaces, alignments, profiles, corridors, pipe networks, points, parcels, feature lines and data shortcuts. It has never been tested in a real Civil 3D.
