Custom fields integration
MCP for ACF & ACF Pro
Advanced Custom Fields stores its values as post meta. WP MCP exposes them through a read/write dispatcher plus flat tools, so an AI agent can list field groups, read field values, and update them on a post. Because ACF values are ordinary meta, the standard post snapshot captures them and rollback restores them exactly. Writes are opt-in.

Frequently asked
Questions, answered.
