How do I install Onshape?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Onshape need an API key?

No required environment variable is listed on this record.

What transport does Onshape use?

Onshape runs locally over stdio.

Setup

Clone the repository:

git clone https://github.com/hedless/onshape-mcp.git
cd onshape-mcp

Create a virtual environment:

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

Install dependencies:

pip install -e .

Set up environment variables:

export ONSHAPE_ACCESS_KEY="your_access_key"

Getting Onshape API Keys

Go to Onshape Developer Portal
Sign in with your Onshape account
Create a new API key
Copy the Access Key and Secret Key

Usage

Running the Server

onshape-mcp

Or directly with Python:

python -m onshape_mcp.server

Configuring with Claude Code

Add to your ~/.claude/mcp.json:

{
  "mcpServers": {
    "onshape": {
      "command": "/absolute/path/to/onshape-mcp/venv/bin/python",
      "args": ["-m", "onshape_mcp.server"],
      "env": {
        "ONSHAPE_ACCESS_KEY": "your_access_key_here",
        "ONSHAPE_SECRET_KEY": "your_secret_key_here"
      }
    }
  }
}

Important Notes:

Use the absolute path to your virtual environment's Python executable
Find your path: cd onshape-mcp && pwd to get the directory path
On Windows: Use C:/path/to/onshape-mcp/venv/Scripts/python.exe
Replace the API keys with your actual keys from Onshape Developer Portal
Restart Claude Code after editing mcp.json

Verify it works: Ask Claude Code: "Can you list my Onshape documents?"
