Revit MCP: connect Claude to Revit, AutoCAD & Civil 3D
Revit MCP lets an AI assistant like Claude operate a live Revit, AutoCAD or Civil 3D session through the Model Context Protocol — reading and editing your model in plain language. HMK Pilot makes the connection one click, and everything runs locally on your machine.
What is MCP (Model Context Protocol)?
The Model Context Protocol is an open standard for connecting AI assistants to real tools and data. Instead of copy-pasting context into a chat, an MCP client (like Claude Desktop or Claude Code) connects to an MCP server that exposes concrete actions — and the assistant calls them directly. Think of it as a common plug between your LLM and the software you already use.
HMK Pilot runs that MCP server inside your Autodesk application, so the assistant works against your live model — not a stale export.
How HMK Pilot connects your Autodesk apps
One suite covers all three applications, with 190+ real actions in total:
- Revit — a built-in chat panel plus an MCP bridge, with 90+ actions: select elements, edit parameters, create sheets, run clash checks, and more.
- AutoCAD — around 70 actions over MCP: draw and modify geometry, manage layers and blocks, plot to PDF.
- Civil 3D — around 30 actions: query alignments, surfaces, pipe networks, corridors and COGO points.
Most competing setups target a single app. HMK Pilot brings the same Claude-driven workflow across Revit, AutoCAD and Civil 3D from one install. See how it compares to other Revit MCP options.
One-click setup — no JSON editing
Connecting an LLM to your model usually means hand-editing claude_desktop_config.json and restarting everything. HMK Pilot writes that configuration for you — one click for Claude Desktop, one for Claude Code — and preserves any MCP servers you already use. You bring your own Claude account; there is no separate AI fee.
What you can do
Drive your model with plain-language requests, for example:
- “Tag every door in the current view and put it on a new sheet.”
- “Set the Fire Rating of all walls on Level 2 to 60 minutes.”
- “Export IFC and NWC from these ten Revit models overnight.”
- “List every alignment in this Civil 3D drawing with its length.”

Frequently asked questions
What is Revit MCP?
Revit MCP means connecting Revit to an AI assistant through the Model Context Protocol (MCP) — an open standard that lets tools like Claude call real actions in another application. HMK Pilot runs a local MCP server inside Revit (and AutoCAD and Civil 3D) so your LLM can read and edit the live model.
Does it work with Claude Desktop and Claude Code?
Yes. HMK Pilot writes the connection into Claude Desktop and Claude Code with one click, preserving any other MCP servers you already have. You use your own Claude account — there is no separate AI fee from HMK Tools.
Does MCP work in AutoCAD and Civil 3D too?
Yes. The same architecture exposes around 100 actions across AutoCAD and Civil 3D — drawing and editing geometry, querying alignments, surfaces and pipe networks — on top of 90+ actions in Revit. In Revit you also get a built-in chat panel; in AutoCAD and Civil 3D you drive it through Claude.
Does my model leave my computer?
No. The MCP server is bound to localhost and everything runs on your machine. Your models and drawings are never uploaded to an HMK cloud; the assistant only acts on what you explicitly ask.
Do I need to edit JSON config files?
No. HMK Pilot's one-click setup writes the config for you. Many community MCP servers require hand-editing claude_desktop_config.json — HMK Pilot removes that step.
