MCP requires the matching prompts or competitors permission. Competitor writes require current admin permission. Personal review sessions additionally require user-authorized OAuth and are unavailable to workspace service keys. Identity decisions verify the discovered candidate revision and replay by UUID. Review applications report per-item outcomes; inspect conflicts before continuing. ## OpenAPI ````yaml POST /api/v2/brands/decisions openapi: 3.1.1 info: title: chatobserver public API version: '2026-09-09' description: >- Track AI visibility, manage prompts, inspect collected answers and citations, and integrate workspace data with your own tools.
