Description

Taxonomies go beyond categories and tags the moment plugins like WooCommerce or Advanced Custom Fields enter the picture — Easy MCP AI returns every registered taxonomy, built-in and custom, so your AI client understands the full content-organization model before filtering posts or assigning terms. Knowing which taxonomies exist is what separates an AI that guesses from one that acts correctly. Easy MCP AI's pure-PHP design means this discovery call hits your WordPress database directly, with no external service involved.
