Scored across 5 tools
Most tools are clearly distinct: schema inspection (list_tables, describe_table), SQL generation (generate_query), and query execution (run_readonly_query). execute_generated_query overlaps by combining generation and execution, but its DANGEROUS warning and guidance to prefer the separate steps mitigate confusion.
All tool names follow a consistent snake_case verb_noun pattern, with optional qualifiers like readonly and generated. The naming clearly indicates the action and target (list_tables, describe_table, generate_query, run_readonly_query, execute_generated_query).
Five tools is well-scoped for a read-only database interface: schema exploration, query generation, exact query execution, and a dangerous combined shortcut. Each tool contributes a distinct capability without unnecessary bloat.
The tool surface covers the complete read-only workflow: see what tables exist, inspect schema, translate natural language to SQL, and execute read-only queries. The optional generate-and-execute tool also fills the convenience path without introducing an obvious dead end.
