ipt-mcp is an open-source (Apache-2.0) Model Context Protocol gateway that lets Claude Code — and any MCP-capable client — drive Autodesk Inventor 2022-2027 locally.

The agent speaks MCP over stdio. The server speaks NDJSON over a local authenticated transport (TCP or Named Pipe) to a per-version in-process Inventor add-in. The add-in marshals every command onto Inventor’s STA thread and talks to the Inventor API.

Your model stays on your machine.

Real-world example: a native Inventor drawing

This mechanical assembly and installation sheet was created and refined in Autodesk Inventor 2027 through an agent-driven ipt-mcp workflow—not a rendered mockup. The workflow used native drawing tools and inventor_send_code, with human direction, review and edits.

Click the image to inspect the full-resolution sheet (4096 × 2893).

• 15 views: assemblies, exploded arrangements, sections and enlarged details.
• 111 native dimensions and 21 item tags, plus two parts lists.
• English annotations and a custom title block, with an embedded BIMwright logo and blank project fields.
• MCP-assisted refinement: matching dimension styles, aligning annotations and exporting the finished sheet as a PNG.

This is a human-reviewed presentation example, not a fabrication release or a one-prompt automatic result. Only the presentation image is included; project models are not distributed.

What ipt-mcp Is

Two processes, one local pipe:

• Bimwright.Ipt.Server.exe — a .NET 8 MCP stdio server launched by Claude Code, Cursor, Cline, Codex, or another stdio MCP client. It has no Inventor reference; it only compiles the API-agnostic contract files, so it builds and runs on any machine with the .NET 8 SDK.
