Abilities API

Join me live as we dive into the Abilities API, the foundation of WordPress’ new AI Layer. We’ll explore how WordPress defines and executes “abilities” — AI-powered actions that can be called from PHP, JavaScript, or even external tools like VS Code or Claude through the Model Context Protocol (MCP).

We’ll explore how to register custom abilities, expose them to AI models, and understand how this fits into WordPress’ broader AI architecture alongside the MCP Adapter and PHP AI API.
