Each tool targets a distinct step in the workflow: discovery (list_tables), schema inspection (describe_table), and data retrieval (run_query). There is no meaningful overlap, and describe_table's argument explicitly references list_tables' output.

All three tools use a consistent snake_case verb_noun pattern (list_tables, describe_table, run_query). The naming is predictable and self-explanatory.

Three tools is minimal but well-matched to a read-only SQL exploration surface; each earns its place. It sits at the low end, though run_query alone could handle much of the work, making the set feel slightly thin.

The read-only discovery-plus-query lifecycle is fully covered, and run_query is a general escape hatch for anything else. Write operations are intentionally excluded (documented as read-only), so this is a deliberate scope limit rather than a gap, though no schema-dump or pagination aid exists.
