Is Drupal Still a CMS? Its New Role in the Agentic Stack

For most of its history, Drupal has been easy to describe: a CMS, or for developers, a content management framework.

That is still true. But in 2026, it is becoming incomplete.

Through projects such as AI Search, AI Agents, Tool API, and MCP Server, Drupal can now participate in RAG pipelines, expose application capabilities as tools, and allow external AI agents to interact with a site.

What makes this interesting is not that Drupal suddenly "has AI."

It is that much of the architecture agents need was already there.
