Scored across 8 tools
Each tool has a distinct role, and the descriptions explicitly steer callers between the overlapping-looking paths (answer vs. select_schema + run_query, semantic_query vs. run_query). The main ambiguity is that answer and semantic_query both involve the server's model, but the guidance on when to prefer each is clear enough.
All names use snake_case and are readable, with most following a verb_noun pattern (select_schema, run_query, describe_object, list_objects, refresh_catalog). The standalone nouns 'answer' and 'health' are minor deviations but remain clear.
Eight tools is well within the sweet spot for a read-only schema-gateway server. Discovery, schema selection, description, querying, semantic filtering, catalog refresh, and health each earn a place without redundancy.
The read-only lifecycle is well covered: list objects, select relevant schema, describe objects, run queries, optionally semantic-filter, refresh catalog, and check health. Minor gaps might include explicit SQL validation or richer pagination controls, but agents can work around these.
