A4.2/5.0

Scored across 3 tools

Disambiguation5/5

The three tools have clearly distinct purposes: listing databases, listing tables with metadata, and executing SQL queries. There is no realistic ambiguity about which tool an agent should choose for a given operation.

Naming Consistency5/5

All tool names follow a consistent verb_noun snake_case pattern: list_databases, list_tables, and run_query. This makes the tool surface predictable and easy to navigate.

Tool Count5/5

Three tools is a compact but well-scoped set for a database MCP server: discovery of databases, discovery of tables, and execution of SQL. Each tool earns its place and there is no redundancy.

Completeness5/5

The set covers the full workflow of exploring and querying a ClickHouse instance: list databases, inspect table schemas, then run queries. Advanced operations such as EXPLAIN and DESCRIBE are accessible through run_query, with write operations config-gated, so there are no obvious dead ends.
