create-post and update-post can now write serialized block markup directly through a new content_blocks parameter, or content_blocks_base64 when the site firewall blocks the request. The markup is saved as sent, with no conversion, so custom blocks, inner-block trees, block bindings and inline formats with data attributes no longer have to be pasted in through the editor. It is validated first: it must parse to at least one block, HTML outside block comments is refused (plain HTML still goes through content_html), and every block name must be registered on the site unless allow_unregistered is true. content_md, content_html, content_blocks and content_blocks_base64 are mutually exclusive. Both abilities now report block_types (every block name in the saved content with its count, inner blocks included) and unregistered_blocks, and read the stored content back after saving, returning content_verified and a notice when WordPress altered it on save. The ability descriptions are updated to match. New error codes: freeform_content, no_blocks, unregistered_blocks, invalid_base64.

create-post and update-post now accept a post_parent of another post type where the child type allows it. Allowed parent types are set per post type through the new lh_mcp_general_abilities_return_allowed_parent_types filter: by default a hierarchical type takes a parent of its own type and a non-hierarchical type takes none, so existing behaviour is unchanged until a plugin opts a type in (for example minutes parented by their event). A parent must also exist, not be in the trash and be readable by the caller; it need not be a draft. list-post-types reports each type’s allowed parents as parent_types. Error codes post_type_not_hierarchical and parent_type_mismatch are replaced by parent_not_allowed and parent_type_not_allowed, and parent_not_readable is new.
