Quick Start Guide

Get up and running with Conjure in under 5 minutes.

Overview

Conjure connects AI assistants (like Claude) to your CAD software, letting you describe parts in natural language and have them built automatically. This guide will get you creating your first design in minutes.

Step 1: Get Your API Key

Sign up for Conjure and choose your tier (free tier available, no credit card required)
Verify your email address
Your API key will be shown after verification
Copy your API key (you'll need it in Steps 3 and 4)

Free Tier Available: Start with the free tier (500 operations/month) or choose a paid plan for more capacity. See pricing for plan details.

Step 2: Install the Adapter

Choose your CAD software:

FreeCAD

Recommended

Quick install (Linux/macOS):

curl -sSL https://conjure.lautrek.com/install.sh | bash

Windows (PowerShell):

iwr -useb https://conjure.lautrek.com/install.ps1 | iex

Or download manually and extract to your FreeCAD Mod directory.

Fusion 360

Download the add-in from Downloads
In Fusion 360: Tools → Add-Ins → Scripts and Add-Ins
Click + and select the extracted folder
Click Run

AutoCAD

Beta

Download the plugin from Downloads
Extract to %APPDATA%\Autodesk\ApplicationPlugins
Restart AutoCAD
Type CONJURE in the command line to activate

Step 3: Connect to Conjure

Activate the adapter in your CAD software:

Open FreeCAD
Switch to the Conjure workbench (View → Workbench → Conjure)
Click Connect in the toolbar
Paste your API key when prompted
You should see "Connected" in the status bar

Click the Conjure button in the toolbar
Enter your API key
Click Connect

Type CONJURE in the command line
Enter your API key in the dialog
Click Connect
The status bar will show "Conjure: Connected"

Step 4: Configure Your AI Assistant

Conjure uses the Model Context Protocol (MCP) to connect with AI assistants. Choose your tool:

Claude Desktop / Claude Code

Add to your Claude MCP configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux (Claude Code): ~/.claude.json

{
  "mcpServers": {
    "conjure": {
      "command": "uvx",
      "args": ["conjure-mcp"],
      "env": {
        "CONJURE_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Cursor IDE

Create .cursor/mcp.json in your project root (or ~/.cursor/mcp.json for global):

{
  "mcpServers": {
    "conjure": {
      "command": "uvx",
      "args": ["conjure-mcp"],
      "env": {
        "CONJURE_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Windsurf IDE

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "conjure": {
      "command": "uvx",
      "args": ["conjure-mcp"],
      "env": {
        "CONJURE_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

OpenAI ChatGPT Desktop / Agents SDK

ChatGPT Desktop uses the same MCP config format. For the Agents SDK:

from agents import Agent
from agents.mcp import MCPServerStdio

conjure = MCPServerStdio(
    command="uvx",
    args=["conjure-mcp"],
    env={"CONJURE_API_KEY": "YOUR_API_KEY_HERE"}
)

agent = Agent(name="CAD Assistant", mcp_servers=[conjure])

Replace YOUR_API_KEY_HERE with your API key. Restart your AI tool after saving. See all CLI tools →

Step 5: Create Your First Design

Now you can use an AI assistant (Claude, ChatGPT, etc.) with Conjure. Here's an example conversation:

You: Create a 50mm cube with 5mm fillets on all edges

AI: I'll create that for you.

# Conjure creates:
1. Box: 50mm x 50mm x 50mm
2. Fillet: 5mm radius on all 12 edges

Try these example prompts:

"Create a cylinder, 20mm diameter, 40mm tall"
"Make a phone stand with 60 degree angle"
"Create a box and cut a 10mm hole through the center"
"Add an M6 threaded hole to the top face"

Step 6: Export Your Design

When you're happy with your design:

For 3D printing: "Export as STL"
For CNC/manufacturing: "Export as STEP"
For sharing: "Export as 3MF"

Pro tip: All export formats are available on all tiers, including the free tier.

Troubleshooting

Check your internet connection
Verify your API key is correct
Make sure you're not behind a restrictive firewall

Ensure files are in the correct Mod directory
Restart FreeCAD completely
Check View → Workbenches menu

Verify connection status shows "Connected"
Check you haven't exceeded your operation limit
Try reconnecting
