Autodesk publishes MCP servers for AutoCAD, Civil 3D, Revit and Fusion, plus a server that answers questions from its help documentation. They aren't interchangeable. Some work with outside AI applications such as Claude, one works only inside Autodesk's own assistant, and one is explicitly a sample.
This guide sets out what Autodesk documents for each. We haven't installed or tested them, and statuses here change quickly, so check the date at the top.

"No status stated" means Autodesk's page doesn't give a beta, preview or similar label. It doesn't mean the product is finished.
AutoCAD and Civil 3D
The AutoCAD and Civil 3D MCP Server runs inside Autodesk Assistant, on Windows. Assistant is the only client Autodesk lists for it, and Autodesk documents no way to connect Claude, Cursor or another outside application. Autodesk describes Assistant itself as being in Tech Preview.
What it can do depends on the product. In plain AutoCAD it offers read and analysis tools. In Civil 3D it can also modify objects and work with Civil 3D styles.
If you want Claude or Cursor to work with AutoCAD, you need a community server. The AutoCAD page lists them, and the comparison of AutoCAD MCP servers sets out how they differ.
Revit
The Revit Public MCP Server is a local add-on, and Autodesk labels it a Technical Preview. During the preview it's supported only on Revit 2027.2, and Autodesk says features may change before general availability.
It comes in three configurations:
- Read queries and reports, and doesn't modify the model.
- Write adds tools that can modify the model.
- Experimental adds further tools, which can also modify the model.
Unlike the AutoCAD server, this one is open to outside applications. Autodesk's page uses Claude Desktop and Cursor as examples and says any AI client that supports local MCP servers can be used. For earlier Revit versions, see the community servers on the Revit page.
Autodesk also publishes a sample server for Revit Automation, which runs Revit jobs on cloud models through the Automation API without desktop Revit. Autodesk calls it an exploratory proof of concept, not a supported product.
Fusion
Autodesk documents three Fusion servers, which suit different jobs:
- The Fusion MCP Server turns a running copy of the Fusion desktop app into an MCP endpoint, for modelling, running commands and inspecting the active document. It must be switched on under Preferences, General, API. Autodesk names Claude Desktop, Cursor and "any MCP-capable HTTP client".
- The Fusion Data MCP Server reads Fusion's manufacturing data through Autodesk's cloud, covering hubs, projects, folders and items. You don't need Fusion installed, but you do need an Autodesk account with access to that data. Autodesk names Claude Desktop and VS Code.
- The Fusion Compute MCP Server runs Fusion without its window in Autodesk's cloud. Autodesk labels it a public beta and says tools and behaviour may change. It needs an active Fusion licence and a Fusion Team hub.
The Fusion page lists these alongside community servers.
Documentation only: Product Help
The Product Help MCP Server searches Autodesk's help and support content. It's hosted by Autodesk, and its page lists no sign-in requirement. It covers many products, including Navisworks and Inventor.
It doesn't operate any software. It's useful for questions about commands and error messages, but it can't read or change your drawings. Keep this in mind when you see a claim that a product "has an official MCP server".
Skills for developers
Autodesk's two skills are aimed at people writing plug-ins, and neither connects an assistant to a running application:
- AutoCAD API Skills, from the Autodesk Developer Network, teach a coding agent to write .NET 10 plug-ins for AutoCAD, Civil 3D and Plant 3D.
- The LISP-to-.NET skill, a preview release, ports AutoLISP routines to .NET plug-ins for cloud Design Automation.
If you're unsure how skills differ from servers, see MCP servers vs agent skills.
Can I use these with Claude or ChatGPT?
It depends on the server, and the table above shows what Autodesk documents for each.
- Claude Desktop: the Revit, Fusion and Fusion Data servers name it. See how to connect Claude.
- ChatGPT: of these, our listing data records it for the Fusion Compute and Product Help servers.
- AutoCAD and Civil 3D: Autodesk Assistant only, for Autodesk's own server.
These are what the documentation says, as recorded on each listing. Requirements such as subscriptions and licences vary, and Autodesk notes that some AI clients may need their own licence. Our tracker of official servers links to the evidence for each entry.
Before you connect anything that can change a model, work through the security questions and keep a backup. Anything an AI assistant produces in these tools must be checked by a qualified engineer.
