Each tool has a clearly distinct purpose with no ambiguity: copy_data handles data insertion, execute_query and stream_query handle query execution with different output methods, get_table_structure inspects table schema, list_indexes lists indexes, and list_views lists views. The descriptions clearly differentiate their functions, making misselection unlikely.

All tools follow a consistent verb_noun naming pattern (copy_data, execute_query, get_table_structure, list_indexes, list_views, stream_query). The naming is uniform throughout, using snake_case and clear action-object pairs, making the tool set predictable and easy to understand.

With 6 tools, the count is well-scoped for a database server, covering core operations like querying, data insertion, and schema inspection. It feels slightly lean but reasonable, as it includes essential functions without being overwhelming. A few more tools for updates or deletions might enhance coverage, but it's not a significant gap.

The tool set covers query execution, data copying, and schema inspection well, but there are notable gaps in CRUD operations. It lacks tools for updating or deleting data, creating or modifying tables, or managing users/roles. This could cause agent failures for common database workflows beyond basic querying and insertion.
