Autodesk MCP Platform

Let any MCP-compatible AI assistant read and edit Autodesk Civil 3D drawings through tools - alignments, surfaces, corridors, pipe networks, quantity takeoff, cut/fill and more.

AI client (Claude Desktop, Cursor, VS Code, Cline, ...)
        |  Model Context Protocol (stdio)
        v
Autodesk.MCP.Server   (TypeScript / Node.js - product-agnostic MCP server)
        |  JSON-RPC 2.0 over a local Windows named pipe
        v
Civil3D.Bridge        (C# / .NET 8 plugin loaded inside Civil 3D)
        |  Autodesk .NET API (in-process)
        v
Autodesk Civil 3D 2025 / 2026

  • No network: everything runs on local named pipes, ACL'd to the current user.

  • Dynamic discovery: the server learns the entire tool catalog from the bridge at handshake time - no tool is hardcoded, and future products plug in with zero server changes.

  • Safe editing: editing tools run in transactions and require confirmation.

Quick start

  1. Install the bridge: copy the Civil3D.Bridge.Bundle-<version>.bundle folder from a release into %APPDATA%\Autodesk\ApplicationPlugins\ and restart Civil 3D. It loads automatically — NETLOAD is not part of normal use.

  2. Install the server: npm install -g autodesk-mcp-server (or npx -y autodesk-mcp-server@latest).

  3. Point your AI client at the server (ready-made configs in examples/clients/).

Civil 3D and your AI client can be started in any order, and either can be restarted without touching the other: the server watches the endpoint registry continuously and pushes tool-list updates as bridges come and go. See docs/Installation.md for the full connection walkthrough, including how to diagnose "Discovered 0 tools".

See docs/QuickStart.md and docs/Installation.md for the full walkthrough.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
