ZPL Er MCP Server

What is ZPL-er?

ZPL-er is a Model Context Protocol (MCP) server that converts ZPL (Zebra Programming Language) code into PNG images. It is designed to help AI models generate and iterate on shipping labels, barcodes, and other ZPL-based designs by providing visual feedback.

How to use ZPL-er?

Install via go install github.com/goalves/zpl-er@latest, then configure the server in your MCP client settings (e.g., Claude Desktop) with the command "zpl-er". The server communicates over stdin/stdout.

Key features of ZPL-er

• Converts ZPL code to PNG images for visual inspection
• Provides visual feedback to help AI models iterate on designs
• Bridges the gap between ZPL code and its rendered output
• Helps debug ZPL positioning and formatting issues

Use cases of ZPL-er

• Generating ZPL code from design requirements (e.g., Figma exports)
• Converting ZPL to PNG for direct visual inspection
• Iterating on label designs by comparing generated output with target designs
• Debugging ZPL positioning and formatting issues
