list_targeting_attributes remains a tool because it searches a potentially large targeting catalog.
These resources read the same versioned public reference endpoints available to REST integrations. They contain no internal planning prompts or voice implementation fields.
Planning versus public write fields
The study-type catalog returns current planning templates instudy_types[]. These templates describe use cases; create_study.study_type describes the research method and accepts in-depth-interview, concept-test, or prototype-test. Historical use-case labels on existing studies may not be selectable templates. Do not use catalog prompts to draft a moderator guide in the MCP host. customize_study applies the selected template instructions.
The voices resource returns { voice, name } choices. Pass only the voice value, male or female, to public study tools; the name is a display label. No external preview URLs are exposed by this catalog.
list_targeting_attributes gives readable panel targeting labels and their IDs. Saved study targeting also resolves to readable labels; check approximation notes before describing who qualifies. Panel targeting does not apply to BYOP studies.
Concept links and images are managed through customize_study, not separate MCP tools.
