The project is a Model Context Protocol (MCP) server designed to convert Mermaid diagrams into PNG images. It provides features for customizing diagram themes and background colors and integrates seamlessly with AI assistants using MCP protocol. The server leverages Puppeteer for high-quality rendering.

Doesn't Claude desktop already support mermaid via canvas?

Yes, but it doesn't support the theme and backgroundColor options. Plus, having a dedicated server makes it easier to create mermaid diagrams with different MCP clients.

Why do I need to specify CONTENT_IMAGE_SUPPORTED=false when using with Cursor?

Cursor doesn't support inline images in responses yet.
