HMK Pilot runs a secure local MCP server inside your Autodesk application and exposes 190+ real actions, so an AI assistant like Claude Desktop or Claude Code can read and edit the live model in plain language — not a stale export.

Part of HMK Tools. Full guide: hmktools.com/revit-mcp · Comparison: vs other Revit MCP options

What it does

• Revit — 90+ actions: select elements, edit parameters, create sheets, tag views, run clash checks, export IFC/NWC, and more. Also a built-in chat panel.
• AutoCAD — ~70 actions: draw & modify geometry, manage layers & blocks, plot to PDF.
• Civil 3D — ~30 actions: query alignments, surfaces, pipe networks, corridors, COGO points.
• Runs 100% locally (bound to localhost) — your models and drawings never leave your machine.
• One-click setup for Claude Desktop and Claude Code (writes the config and preserves any other MCP servers you already have).
• Optional Roslyn execute_autocad_code / execute_civil_code escape hatch (toggle off in Settings → Security).

Requirements

• Windows (x64)
• Autodesk Revit 2023–2027 and/or AutoCAD / Civil 3D 2021–2026
• Node.js (v20 LTS) — for the local bridge
• Claude Desktop or Claude Code (bring your own Claude account)
• An HMK Tools license — free 30-day trial, no card

2. In Revit / AutoCAD / Civil 3D, open the HMK Tools → Pilot AI ribbon and toggle the Connector on.
