HMK Pilot — MCP for Revit, AutoCAD & Civil 3D

Drive your Autodesk apps from Claude, in plain language, over the Model Context Protocol.

---

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).
