Which integrations are available for this server?

Provides tools for interacting with Autodesk Fusion 360, enabling CAD automation through sketching, 3D modeling, body operations, assemblies, sheet metal, inspection, parameters, and CAM/manufacturing.

How do I use Fusion360 MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Fusion360 MCP Server Create a 50mm circle and extrude it 10mm" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Fusion360 MCP Server

Beta — This project is under active development. APIs and tool behavior may change between releases. Use at your own discretion. Feedback and bug reports welcome via GitHub Issues.

MCP server that connects AI coding agents to Autodesk Fusion 360 for CAD automation.

Tested with Claude Code. Works with any MCP-compatible client — OpenCode, Codex, Cursor, or anything that speaks the Model Context Protocol.

How it works

Any MCP Client ←(stdio MCP)→ This Server ←(TCP :9876)→ Fusion360MCP Add-in ←(CustomEvent)→ Fusion Main Thread

Two components:

MCP Server (this repo) — Python process that speaks MCP protocol to Claude and forwards commands over TCP
Fusion360MCP Add-in (installed in Fusion's AddIns folder) — runs inside Fusion 360, executes API calls safely on the main thread

Related MCP server: Fusion360 MCP Server

Prerequisites

uv (Python package manager)
Autodesk Fusion 360
An MCP-compatible client (Claude Code, OpenCode, Codex, Cursor, etc.)

Installation

1. Install the Fusion 360 Add-in

Quick install (symlink for development):

./scripts/install-addon.sh

Manual install:

# macOS
cp -r addon ~/Library/Application\ Support/Autodesk/Autodesk\ Fusion\ 360/API/AddIns/Fusion360MCP

# Windows (PowerShell)
Copy-Item -Recurse addon "$env:APPDATA\Autodesk\Autodesk Fusion 360\API\AddIns\Fusion360MCP"

Then start it in Fusion: Shift+S → Add-Ins → Fusion360MCP → Run

You should see [MCP] Server listening on localhost:9876 in the TEXT COMMANDS window.

2. Connect your MCP client

The MCP server is published on PyPI — no need to clone this repo.

Claude Code

claude mcp add fusion360 -- uvx fusion360-mcp-server --mode socket

Other MCP clients

The server runs over stdio, so any MCP-compatible client can launch it. The command is:

uvx fusion360-mcp-server --mode socket

{
  "mcpServers": {
    "fusion360": {
      "command": "uvx",
      "args": [
        "fusion360-mcp-server",
        "--mode", "socket"
      ]
    }
  }
}

3. Verify

Call the ping tool from your client. If it returns {"pong": true}, everything is connected.

Uninstalling

Remove the fusion360 entry from your MCP client config
Stop the add-in in Fusion (Shift+S → Add-Ins → Fusion360MCP → Stop)
Delete the add-in folder from Fusion's AddIns directory

MCP Protocol Features

Tool annotations — each tool is tagged with readOnlyHint, destructiveHint, and idempotentHint so MCP clients can auto-approve safe operations
Resources — fusion360://status, fusion360://design, fusion360://parameters for passive state inspection
Resource templates — fusion360://body/{name}, fusion360://component/{name} for dynamic entity lookup
Prompts — create-box, model-threaded-bolt, sheet-metal-enclosure workflow templates
Structured errors — tool results include isError=True when the add-in reports failures
Mock mode — --mode mock returns plausible test data without Fusion running (all responses include "mode": "mock")

Development

uv sync --dev       # install deps
uv run pytest -v    # run tests (171 tests)
uv run ruff check   # lint

Notes

All Fusion API units are centimeters (Fusion's internal unit).
One operation per tool call. Batching multiple operations crashes the add-in.
Commands time out after 30 seconds.
Add-in logs to ~/fusion360mcp.log.
The undo tool includes a design-type safety guard — it checks before/after and auto-redoes if the undo would switch from parametric to direct mode.
