fusion360-mcp-server (aurafriday)
Fusion 360 add-in that exposes the app as an MCP tool so AI agents can drive it, including arbitrary Python execution inside Fusion with thread-safe API calls; also listed on the Autodesk App Store.
What it does and how it connects
This Fusion 360 add-in connects Fusion to the Aura Friday MCP-Link server so AI agents can drive it as a remote tool, and it is also listed on the Autodesk App Store. The add-in exposes Fusion through generic API calls, arbitrary Python execution inside Fusion, and calls to other MCP tools, with all Fusion API calls executed on the main thread through a work queue.
An agent can run any Fusion API command by path, or run Python with full access to adsk.core, adsk.fusion and adsk.cam, loaded add-ins, SQLite databases, browser automation and user popups, with pre-injected shortcuts for app, ui, design and rootComponent. Three documentation sources are available: live API introspection, Autodesk's online docs with code samples, and a built-in best-practices guide.
The README states the add-in covers Fusion's electronics design, CAM with more than 280 classes, McMaster-Carr component insertion and simulation, all through the same Python path. Python execution has full system access with no sandboxing, which the README flags directly, and the license is proprietary: the source is visible in the repository but all rights are reserved by Aura Friday.
What engineers report
exec into globals() with no isolation means one prompt-injected instruction anywhere in an agent's context can run arbitrary code in the CAD host.

Recurring errors it addresses
Error Index entries this tool is built to reduce or work around.
- Cloud-first file model makes local file control, rename/move/backup workflows feel alien and risky.Error Index
- General UI/UX is described as confusing and hostile for routine work.Error Index
- ChatGPT's Computer Use agent cannot drive Autodesk Fusion 360: selecting Always allow does not stick, a later window-state request fails with 'Computer Use was not approved to use fusion360', and the requested CAD design could not be created. Desktop logs recorded three allow-persist-always approvals with no persisted entry in the config.Error Index
- STEP carries geometry only and sketch DXF only 2D profiles, so moving a Fusion design to another parametric CAD tool loses its intent. The proposal is a JSON export of user parameters, the feature timeline, sketch constraints and component transforms, with the STEP kept as the reference to check the rebuild against by volume and bounding box.Error Index
