ECA Guide Makes Drupal Automation Documentation Readable to AI Agents

Machine-readable documentation is the focus of a 1 July 2026 LakeDrops post by LakeDrops author Jürgen Haas, The ECA Guide Revolution: Documentation Meets AI. The post is part of the ECA: The Next Chapter series and explains how the ECA Guide, documentation for the Event-Condition-Action project, has been prepared for use by AI agents. Jürgen frames the change as a shift from documentation as human-facing reference material to documentation as infrastructure that software can search, read, and apply.

According to Jürgen, the ECA Guide covers 1,206 plugins, including 266 events, 94 conditions, and 846 actions. Machine-readable access includes a public Model Context Protocol server at ecaguide.org/mcp, the llms.txt and llms-full.txt indexes, clean Markdown versions of documentation pages, and an ECA agent skill published under the guide’s .well-known path. He says these entry points let agents search the guide, read specific pages, locate sections, and use ECA concepts, plugin references, token guidance, and examples without relying only on the human-facing HTML interface.

The post gives an example of an agent building a model from a natural-language workflow by reading event, action, and token documentation before generating the model structure. Jürgen also reports about 11,400 human visits and 17,300 human page views over six months, compared with about 244,000 machine visits and 734,000 machine page reads through the MCP server, while cautioning that machine traffic includes crawling and indexing. He argues that the same pattern could support other Drupal configuration systems, including Views, Layout Builder, Workflows, permissions, and Commerce, and says future work aims to bring AI assistance into the new Workflow Modeler.
