Revit MCP: put AI to work in your live Revit model
Revit MCP lets an AI assistant like Claude operate a live Revit session through the Model Context Protocol — reading and editing your model in plain language, with 100+ real Revit actions. Pilot AI 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 (Claude, ChatGPT, Cursor, Antigravity) 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.
Pilot AI runs that MCP server inside your Autodesk application, so the assistant works against your live model — not a stale export.
What it can do in Revit
Over a hundred real Revit actions, plus something no MCP-only setup gives you — a chat panel built into the ribbon, so you can work without leaving Revit at all:
- Elements — find by category or parameter, select, move, rotate, copy, array and delete, with scopes you set explicitly rather than defaulting to the whole model.
- Parameters — read and bulk-set instance and type values, create and bind project and shared parameters, find and replace across a category.
- Views, sheets and annotation — create views, sections, callouts and schedules, place them on sheets, tag elements, dimension grids, add text.
- Model quality — list and resolve warnings, audit duplicate types and parameters, purge unused, run clash checks between host and links.
- Export — PDF, DWG, IFC and NWC, plus schedules straight to Excel.
- Dynamo — read the open graph, search your installed packages, add and wire nodes, run it and read the results back.
Working in AutoCAD, Civil 3D or Navisworks as well? The same suite covers those too — see AutoCAD & Civil 3D MCP or Navisworks MCP. Or see how this compares to other Revit MCP options.
One-click setup — no JSON editing
Connecting an LLM to your model usually means hand-editing a config file and restarting everything. Pilot AI writes that configuration for you — pick your client and click once — and preserves any MCP servers you already use.
Claude Desktop, Claude Code, ChatGPT / Codex, Cursor and Google Antigravity are set up directly, and any other MCP-compatible client can connect too. You bring your own AI account; there is no separate AI fee.
There is also nothing to install alongside it — no Node.js, no Python, no runtime. The bridge is a single small executable that ships with the installer, which matters on locked-down corporate machines where you could not add one anyway.
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.”
- “Which walls on Level 3 have no Fire Rating set?”

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. Pilot AI runs a local MCP server inside Revit (and AutoCAD, Civil 3D and Navisworks) so your LLM can read and edit the live model.
Which AI clients does it work with?
Claude Desktop, Claude Code, ChatGPT / Codex, Cursor and Google Antigravity are set up with one click, and any other MCP-compatible client can connect too. Existing MCP servers you already have are preserved. You use your own AI account — there is no separate AI fee from HMK Tools.
Which Revit versions are supported?
Revit 2023 through 2027. Each release gets an assembly built against its own runtime — .NET Framework 4.8 for 2023 and 2024, .NET 8 for 2025 and 2026, .NET 10 for 2027 — so no version is running code compiled for a different one.
Can the assistant use Dynamo?
Yes. With Dynamo open it reports what Dynamo is doing, opens or starts a graph, searches the node library including packages you have installed, adds and wires nodes, writes Code Block and Python, runs the graph and reads the computed values and node warnings back — useful both for building a script from a description and for explaining why an existing one is failing.
Does MCP work in AutoCAD and Civil 3D too?
Yes — the same suite covers them, with its own set of drawing, layer, block, alignment, surface and corridor actions. See the AutoCAD & Civil 3D page for what that side does.
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. Pick your client in Settings and click once — Pilot AI writes the config for you. There is also no runtime to install: many community MCP servers need Node.js or Python on the machine, which is exactly what a locked-down corporate build will not allow. The bridge here is a single small executable that comes with the installer.
