Enhanced MCP QR Generator

The Enhanced MCP QR Generator is a dedicated Model Context Protocol (MCP) server that turns arbitrary text or URLs into high‑quality QR codes. By exposing a simple set of MCP tools— and —it lets AI assistants such as Claude or Amazon Q embed QR‑code creation directly into user conversations, eliminating the need for external services or manual encoding steps. This tight integration is especially valuable in workflows that require quick, on‑the‑fly generation of scannable codes for links, credentials, or configuration data.

At its core, the server offers a rich set of customization options. Developers can specify image format (PNG, SVG, base64, or ASCII art), size, margins, foreground and background colors, error‑correction levels, and even embed a logo at the center of the QR code. These features give users fine‑grained control over appearance and resilience, enabling use cases ranging from branded marketing materials to secure QR codes that can survive partial damage. The ability to save generated images directly to disk with user‑defined or auto‑generated filenames further streamlines integration into automated pipelines.

The server’s architecture is intentionally lightweight: a single HTTP endpoint handles JSON‑RPC requests for MCP communication, while a route provides basic monitoring. It runs on port 9999 by default but can be reconfigured via environment variables or Docker Compose, making it straightforward to deploy in containerized environments. The configuration precedence (command line > environment > defaults) gives developers flexibility to override settings at the level that best fits their deployment model.

Real‑world scenarios abound: a marketing team can ask an AI assistant to generate QR codes for new campaign URLs; a software engineer might embed QR codes into documentation that reference dynamic API endpoints; an event organizer could create personalized attendee badges with embedded login links. In each case, the MCP server removes friction by allowing the assistant to produce a ready‑to‑use image without leaving the chat interface.

What sets this server apart is its seamless MCP support combined with advanced rendering capabilities. The inclusion of terminal ASCII art output, for instance, lets developers preview QR codes directly in a console, while the logo‑embedding feature supports brand consistency. Together with Docker support and built‑in health checks, the Enhanced MCP QR Generator offers a robust, developer‑friendly solution for any project that needs reliable, customizable QR code generation within an AI‑augmented workflow.
