Several tools have overlapping purposes: database_execute_sql, database_execute_script, and database_execute_batch all execute SQL but with subtle differences, while database_connect, database_connect_environment, and database_switch_environment cover similar connection territory. The presence of check_node_version, which has nothing to do with database operations, further confuses tool selection.

Most tools follow a consistent database_verb_noun pattern (e.g., database_connect, database_execute_sql), but the lone check_node_version breaks the convention entirely. The naming is readable but not fully uniform.

At 14 tools, the count is at the high end of the typical range but still acceptable for a database server. However, the inclusion of check_node_version, which is unrelated to MySQL/PostgreSQL work, suggests the count could be reduced or the tool placed in a separate utility server.

The tool set covers core database operations well: connecting, disconnecting, testing, executing SQL (single, script, batch), retrieving schema, managing project environments, and listing sessions. Minor gaps like explicit transaction control are not critical for a basic MCP database server, so the surface is fairly complete.
