### Description (declared)

# OCP Viewer MCP Server

[![PyPI version](https://badge.fury.io/py/ocp-viewer-mcp.svg)](https://badge.fury.io/py/ocp-viewer-mcp)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)

An MCP (Model Context Protocol) server that captures screenshots from the [OCP CAD Viewer](https://github.com/bernhard-42/vscode-ocp-cad-viewer), allowing AI assistants like [Cursor](https://cursor.sh) to "see" your 3D CAD models.

## What it does

When working with CAD tools like [CadQuery](https://github.com/CadQuery/cadquery) or [Build123d](https://github.com/gumyr/build123d), you can display models in the OCP CAD Viewer using `show()`. This MCP server lets you ask an AI assistant to capture what's currently displayed, enabling visual feedback and AI-assisted CAD development.

**Example workflow:**
1. You're designing a part in a Jupyter notebook with CadQuery
2. You run `show(my_part)` to display it in the OCP viewer
3. You ask the AI: *"capture the current view - does this geometry look correct?"*
4. The AI captures a screenshot and can analyze the 3D model visually

## Installation

```bash
pip install ocp-viewer-mcp
```

**Requirements:**
- Python 3.10+
- [OCP CAD Viewer](https://marketplace.visualstudio.com/items?itemName=bernhard-42.ocp-cad-viewer) VS Code/Cursor extension
- [ocp-vscode](https://pypi.org/project/ocp-vscode/) Python package (for `show()` function)

## Configuration

### Cursor

Add to your `~/.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "ocp-viewer": {
      "command": "python",
      "args": ["-m", "ocp_viewer_mcp.server"]
    }
  }
}
```

If you're using a virtual environment (recommended), specify the full Python path:

```json
{
  "mcpServers": {
    "ocp-viewer": {
      "command": "/path/to/your/venv/bin/python",
      "args": ["-m", "ocp_viewer_mcp.server"]
    }
  }
}
```

### Claude Desktop

Add to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json` …
