The Pain of Email Development

Today, building a single campaign means copying content into multiple tools: you draft in a CMS, check it on your phone, then paste it into an editor that only shows a preview. You end up spending hours fighting nested tables and debugging why background colors or columns look different when viewed through Outlook versus Gmail.

With this MCP, the process shrinks down to one step. Your agent takes your source markup, uses `render_mjml`, and instantly provides you with production-ready HTML that has already been tested against industry best practices.

Generate Responsive HTML via render_mjml

The manual steps that vanish are: checking for CSS conflicts, ensuring every column is wrapped in the correct table structure, and manually adjusting padding or spacing to accommodate different client limitations.

Now you simply provide the structured input; the MCP handles all the necessary structural changes. It's immediate, reliable HTML.

What MJML Email Markup MCP does for your AI

Email development is a nightmare because every client—Outlook, Apple Mail, Gmail—treats HTML differently. Manually coding these templates means fighting complex nested tables and worrying about CSS inline conflicts. This MCP solves that by letting your AI agent handle the heavy lifting. You provide MJML markup (XML or JSON), and this connector transpiles it instantly into clean, responsive HTML.

It’s like having a senior front-end developer available in chat. Whether you're working directly in an IDE or just chatting with your agent, you get immediate, client-standardized results. Because Vinkius hosts this MCP, you connect once and gain access to industry best practices for email design without needing a specialized build system.
