| Approach | Apps | Read / write | Setup | Support | Cost |
|---|---|---|---|---|---|
| Autodesk Revit Public MCP Server (Tech Preview) | Revit 2027 | Read-focused (queries, counts, snapshots) | Official server + client config | Autodesk (preview) | Free (preview) |
| Open-source community servers | Revit (2023–2027, varies) | Read & write on the capable ones | DIY — clone, build, edit JSON; needs Node or Python | Community / self-support | Free (open-source) |
| Pilot AI (HMK Tools) | Revit + AutoCAD + Civil 3D + Navisworks | Read & write — 330+ actions | One-click, packaged installer — no runtime needed | Commercial + in-Revit chat | Paid (free 30-day trial) |

Autodesk's official Revit MCP server
Autodesk shipped a Revit Public MCP Server as a Tech Preview for Revit 2027. It focuses on read access— querying the model, checking parameters, counts, and capturing view snapshots — as a trusted foundation before broader editing. If you’re on the newest Revit and mainly want to interrogate your model, it’s a solid, official first step. Its limits today are scope (read-focused), Revit-only, and newest-version-only.
Open-source community servers
A lively ecosystem of free, open-source Revit MCP servers exists on GitHub — some very capable, exposing 100+ tools with full read/write. They’re excellent if you’re technical and happy to clone a repo, build it, edit your MCP client’s JSON config, and maintain it yourself. The trade-off is exactly that: setup effort, varying maturity, and community-only support. They’re Revit-focused.
Pilot AI
Pilot AI takes the packaged route. One installer covers Revit, AutoCAD, Civil 3D and Navisworks — the only option here that spans all four — with 330+ read/write actions, one-click setup for Claude, ChatGPT, Cursor and Antigravity (no JSON editing, no runtime to install), a built-in in-Revit chat panel, and commercial support. Everything runs locally. You’re paying for convenience, breadth across apps, and a person to email — instead of building and maintaining it yourself.
Which should you choose?
- Just evaluating on Revit 2027, mostly reading the model: start with Autodesk’s official preview.
- Technical, want free, Revit-only, don’t mind setup: an open-source server is a great fit.
- Want it to just work across Revit, AutoCAD, Civil 3D & Navisworks with support: that’s Pilot AI.
Frequently asked questions
Is Autodesk's official Revit MCP server enough?
If you're on Revit 2027 and mostly need to query and report on your model — find elements, check parameters, counts, snapshots — Autodesk's read-focused Tech Preview is a trusted starting point. If you need broad editing, older Revit versions, or AutoCAD, Civil 3D and Navisworks, you'll want something more capable.
Are the open-source Revit MCP servers any good?
Yes — several community projects are genuinely capable, some exposing 100+ tools with full read/write, and they're free and open-source. The trade-off is setup and maintenance: you clone, build, edit JSON config, and support yourself. Great if you're technical; more friction if you just want it to work.
What makes Pilot AI different?
It's the only option here that spans Revit, AutoCAD, Civil 3D and Navisworks from one packaged install, with one-click setup for Claude, ChatGPT, Cursor and Antigravity (no JSON editing), an in-Revit chat panel, and commercial support. You trade the free DIY route for 'it just works, everywhere, with a person to email.'
Do all of these work with Claude?
Yes. MCP is an open standard, so these servers work with any MCP-compatible client. Pilot AI writes the connection config for you — Claude Desktop, Claude Code, ChatGPT / Codex, Cursor and Google Antigravity are one click each.
Want the one that works everywhere?
Pilot AI across Revit, AutoCAD, Civil 3D & Navisworks — free for 30 days.
