"Add a pricing table and FAQ section to my services page 
using Gutenberg blocks."

→ wp_get_blocks(id=15) → read current block structure

Block Format

WordPress Gutenberg blocks use a structured JSON format with block names, attributes, and inner blocks. mumcp preserves this structure perfectly — your AI can read a page’s blocks, modify specific sections, and write them back without losing formatting, custom classes, or block-level settings. This is the most reliable way to manage WordPress content programmatically.
