Autodesk Fusion MCP Server
Autodesk's built-in local MCP server for Fusion that lets MCP clients send tool requests to a live Fusion desktop session for real-time modeling and command-based actions.
What it does and how it connects
The Autodesk Fusion MCP Server is built into Fusion itself. It is hosted by Fusion and is only available while Fusion is open. It is enabled in Fusion Preferences under General, API, by checking Fusion MCP Server (runs locally on this device), after which Fusion exposes a local MCP server endpoint at http://127.0.0.1:27182/mcp. There is nothing to install and no sign-in step.
MCP clients connect over Streamable HTTP at that local URL. Claude Desktop installs the Autodesk Fusion connector from the connector directory, where it appears with the type Desktop; Cursor and VS Code add the server URL to mcp.json. Any other client that supports MCP over Streamable HTTP can connect to the same URL. The tool list is dynamic: the client discovers the tools when it connects.
Once connected, a client can create, modify, and inspect CAD geometry in the live Fusion session, executing Fusion commands in real time. Autodesk's own verification step is to ask for a 10 mm cube and watch Fusion execute the command. The help page distinguishes this local server from the separate cloud-hosted Fusion Data MCP Server, which works with Fusion data in hubs, projects, and folders with Fusion closed, and is not a replacement for live modeling.

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
- 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
- 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
