Linking your software
“Connectors” › “MCP servers”, “Servers you host” section: open the guide of your software, then “Set up”. Follow its steps and fill in “Server URL” and “Access token”. For Fusion and Archicad, the guide makes the token and puts it in the command to copy; Moon AI refuses a server that answers without that token. MCP servers (Moon AI app)
Fusion
In Fusion: Preferences › General › API, tick Fusion's MCP server (port 27182). Make it reachable over HTTPS with a password, never without: the guide gives the ngrok command with --basic-auth and a password made for you, already in “Access token”. Then paste the https address followed by /mcp.
FreeCAD and CadQuery
Turn on the remote access of the server and copy the access token it generates, or put it behind HTTPS with a token. Then paste the public https address and that token.
Archicad
Archicad goes through a community MCP server, not published by Graphisoft. Install the Tapir add-on in Archicad, start the server with the command of the guide (it holds the token made for you), make it reachable over HTTPS keeping --host-header=rewrite, then paste the address followed by /mcp. Revit goes through Moon CLI. An IFC model attached to a chat is read in the isolated computer.
While you use it
Keep the software and the tunnel open while the AI works, then stop the tunnel: Fusion's server can run scripts on your computer. Actions that change your model ask for your approval, unless you choose “Always allow” or “Act without asking”. An Archicad command that changes the project (elements, saving, closing, Teamwork, files) asks for your approval every time.
