AEC Pilot — MCP for Revit, AutoCAD, Civil 3D, Navisworks and more

Let your AI assistant read and edit the model that is open in your Autodesk app, in plain language.

AEC Pilot runs a local MCP server inside each Autodesk application on yourPC and gives your AI assistant 480+ actions on the open model or drawing.Claude, ChatGPT, Cursor or any other MCP client works on the live model instead ofonly giving advice.

This repository is the public overview. The server ships inside the AEC Pilotadd-in. Full guide: aecpilot.com/mcp

What it does

• Revit: select and edit elements and parameters, create sheets and views,tag, run clash checks, export IFC, drive Dynamo.
• AutoCAD: draw and modify geometry, layers, blocks, layouts, plot to PDF.
• Civil 3D: alignments, profiles, surfaces, corridors, pipe networks, samplelines and section views, COGO points.
• Advance Steel: read and edit the steel model.
• Navisworks: search sets, clash detection, TimeLiner 4D, quantification,viewpoints, append / merge / refresh / publish.
• Inventor: parts, sketches and features, assemblies, iLogic, drawings, BOM.
• 3ds Max: scene objects, modifiers, materials, cameras and lights, rendering.
• Robot Structural Analysis: nodes, bars, supports, loads, analysis and results.

Every app also has an optional code tool (for example execute_revit_code) foranything the fixed actions do not cover. You can switch it off in Settings.

Works with your assistant

AEC Pilot speaks plain MCP, so any MCP client works. These are set up for you inone click from Settings → Setup Guide:

Setup writes only to the clients you have installed, and keeps the MCP serversalready in your config.

Running more than one Autodesk app, or two copies of the same one? Each copy getsits own server entry, so the assistant can tell them apart.

The assistant can also call get_knowledge_template for checked API notes andstep-by-step recipes for each app, instead of guessing.

Privacy

• The server listens on localhost only. Your models and drawings stay on yourmachine.
• AEC Pilot does not send your model anywhere. Your AI client sends what it readsto your own AI provider, under your own account.
• Privacy policy: https://www.aecpilot.com/privacy
