TDQS
Scored across 9 tools
Each tool has a clearly distinct purpose: querying, fetching by ID, creating, updating, deleting, status checks, schema reload, table listing, and table description. No overlapping functionality.
All tools follow a consistent jazz_<verb> pattern with snake_case, e.g., jazz_query, jazz_get_row, jazz_list_tables. Naming is uniform and predictable.
9 tools is well-suited for a Jazz database MCP server. The set covers CRUD operations, schema introspection, and administrative actions without being excessive or thin.
The tool set provides full CRUD coverage (insert, get/query, update, delete), schema exploration (list tables, describe table), and operational management (status, reload schema). No obvious gaps for the domain.
