"Circle" matching MCP servers:

Enables AI agents to drive a live AutoCAD session over stdio with transactional, serialized writes: inspecting and saving documents, managing layers, creating and editing line/circle/arc/polyline/rectangle/text entities, querying selections, setting checkpoints, and exporting DXF. Every request is validated against strict schemas with document revision checks and save-reopen geometry readback, and a headless backend is available when no AutoCAD instance is running.

Enables controlling Autodesk Fusion 360 from any MCP-compatible AI client through natural language. Exposes tools for creating sketches, drawing rectangles and circles, extruding, revolving, filleting, shelling, drilling holes and bolt-circle patterns, managing user parameters, and exporting STEP/STL files, plus batch generation of parametric variants.
