Scored across 6 tools
The specialized tools (query, insert, update, delete, execute_ddl) each map to distinct SQL operations, but the generic execute tool can perform any of these operations, creating overlap and making tool selection less clear.
Most tools use a simple verb form (query, insert, update, delete, execute), while execute_ddl uses a verb_noun pattern. This is a minor inconsistency but the naming is still predictable.
Six tools is an appropriate scope for a PostgreSQL read-write server, providing dedicated operations without bloat.
The surface covers all core SQL operations (SELECT, INSERT, UPDATE, DELETE, DDL) plus a generic escape hatch for arbitrary SQL, so there are no obvious gaps.
