We’ve made several updates to Marketer MCP tools and Agent API endpoints to better support personalization, A/B/n testing, component management, and site data retrieval.
What's included
Variant-specific targeting
You can now use the optional variantId parameter to target a specific personalization or A/B/n test variant. This is supported for Marketer MCP tools and Agent API endpoints related to page management:
retrieving components
setting component datasources
listing allowed components
retrieving HTML, screenshots, and preview URL
When variantId is provided, you can retrieve and update data for a specific variant instead of working with the page only.
Component variant management
New Marketer MCP tools and corresponding Agent API endpoints are available for managing component variants in personalization and A/B/n tests.
You can now:
Hide components on the default page variant of a personalized page.
Reset personalization or A/B/n test setup applied to a component.
Improved API responses
Agent API responses now include additional fields that provide more context.
editablePlaceholders has been added to page details to show placeholder metadata, improving usability and providing better context for API consumers.
is_page_folder has been added under page_locations so agents can identify and discover page folders when retrieving sites and pages.
Authorization updates
OAuth client scopes have been updated to resolve an issue when retrieving all components of a site. The following scopes are now required:
cmp.sites:read
platform.tenants:list
