# ME-QR MCP Server

## Overview

The **ME-QR MCP Server** is a cloud-hosted bridge that lets AI assistants create, update, and manage QR codes on [me-qr.com](https://me-qr.com) on your behalf. Connect once via OAuth, and your assistant can generate QR codes for links, Wi-Fi, vCards, PDFs, images, and more — without leaving the chat.

## Key Capabilities

| Tool | Description |
|---|---|
| `create_qr_link` | QR code for a URL |
| `create_qr_wifi` | QR code for Wi-Fi credentials |
| `create_qr_vcard` | QR code business card |
| `create_qr_text` | QR code containing plain text |
| `create_qr_email` | QR code for an email address |
| `create_qr_pdf` | QR code linking to a PDF |
| `create_qr_image` | QR code linking to an image gallery |
| `list_user_qrs` | List your QR codes |
| `update_qr_*` | Update the content of an existing QR code |
| `customize_qr` | Change the visual style of an existing QR code (pattern, colors, logo, gradient) — ChatGPT only |
| `delete_qr` | Delete one or more QR codes |
| `get_qr_analytics` | Basic scan statistics |
| `get_qr_scan_stats` | Detailed scan statistics — geography, devices, unique scans (Premium) |

## Authentication

The server uses **OAuth 2.1 with PKCE**. When you connect, your AI client opens a browser window where you log in to your me-qr.com account and approve access. No API keys or passwords are shared with the AI client — the client only ever holds an access token scoped to your account email, valid for 30 days.

Clients that can't complete a browser-based OAuth flow can authorize instead with a me-qr.com API key.

## Compatible Clients

Claude Code, Claude.ai, Cursor, Windsurf, and ChatGPT (via custom connectors / Developer Mode).

## Connecting

### Claude Code

```bash
claude mcp add me-qr -s user --transport http https://mcp.me-qr.com/mcp
```

### Cursor / other clients supporting `.mcp.json`

```json
{
  "mcpServers": {
    "me-qr": {
      "type": "http",
      "url": "https://mcp.me-qr.com/mcp"
    }
  }
}
```

### ChatGPT

Enable Developer Mode, add a custom connector pointing to `https://mcp.me-qr.com/mcp`, then authorize with your me-qr.com account.

After connecting, authorize the server once — your client will prompt you to log in to me-qr.com in a browser.

## What this repository contains

This repository holds the public pieces of the ME-QR MCP Server: documentation, client manifests (`.mcp.json`), and the [MCP registry](https://github.com/modelcontextprotocol/registry) entry (`server.json`).

The server itself is a hosted service at `mcp.me-qr.com`. Its source code, OAuth implementation, and token storage are maintained privately by the ME-QR team — see [SECURITY.md](SECURITY.md) for how that's handled and how to report issues.
