MDC File Support

An Obsidian plugin that enables browsing, viewing, and editing .mdc files just like regular Markdown files.

What are .mdc files?

.mdc files are Markdown-based configuration files commonly used by AI coding tools like Cursor for defining project rules and conventions. They follow standard Markdown syntax with YAML frontmatter.

Features

• Native .mdc support — Open and edit .mdc files directly in Obsidian with full Markdown rendering (reading view, editing view, and live preview).
• File explorer integration — .mdc files appear in the file explorer and can be browsed like any other note.
• Create new .mdc files — Quickly create new .mdc files with a default template via the command palette.
• Convert between .md and .mdc — Easily convert files between .md and .mdc formats using commands or right-click context menu.
