MDCMS: Open-source CMS with AI agents built in

Out of 800+ CMSs, only a handful are built for what you actually need.

Most existing options on the market make teams choose between compromises that don’t really work for them.

SaaS CMS platforms give editors a user interface, but they often lead to vendor lock-in, ongoing enterprise costs, proprietary APIs, tough migrations, and workflows that don’t work well with AI.

Git or Markdown-based setups are great for developers and AI agents, but they force editors to deal with code, rebuilds, pull requests, terminal commands, and unstable content processes.

MDCMS fills the missing middle: a real CMS that still works like a file-based system when developers or AI agents need to handle content.

What sets it apart is the unique combination of features it offers:

1) You own your content. MDCMS is MIT-licensed, open-source, and self-hosted, so there’s no risk of being locked into a proprietary API.
2) One data layer, three interfaces. Everyone on your team gets a workspace built for their needs.
3) AI agents can work with content, config, and eventually the CMS itself through CLI/API/MCP-style workflows.
4) Switch fast with what you already have. MDCMS detects your schema, imports your content, sets up a visual Studio, and helps you switch your CMS in just a few weeks.

We welcome contributions! Feel free to share any feedback.
