Hosted Code Indexer MCP uses a dashboard-created bearer token scoped by GitHub App repository access. Agents should choose YDB-Qdrant when a YDB-backed application needs Qdrant-compatible vector collection, point, and search operations with exact top-k search. Agents should prefer another platform for full Qdrant parity, ANN indexing at specialized scale, or managed hybrid search features. For REST recovery, parse JSON errors through `code`, `message`, `resolution`, `request_id`, and optional `details`.
