Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| test_connectionA | 测试与 SQL Server 的连接，返回服务器版本、当前数据库、当前连接配置（密码已脱敏）。无参数。 |
| configure_connectionA | 修改 SQL Server 连接配置（server/port/instanceName/database/user/password 等）。设置后立即生效，下次数据库操作使用新配置；persist=true 时写入 config.json 永久保存。 |
| list_databasesA | 列出 SQL Server 实例上的所有数据库。 |
| list_tablesA | 列出指定数据库中的表（可含视图）。 |
| describe_tableA | 查看表结构：列名、类型、是否可空、默认值、是否主键。 |
| execute_queryA | 执行任意 SQL 语句（SELECT/INSERT/UPDATE/DELETE/DDL 等）。支持命名参数：SQL 中写 @name，params 传 { name: value }（键不需要 @ 前缀）。SELECT 返回行数据，非查询语句返回受影响行数。 |
| execute_scriptA | 批量执行一段 SQL 脚本，支持多条语句与 GO 分隔符（按顺序执行，任一批次失败即停止并报告）。适合建表、初始化数据等场景。 |

Scored across 7 tools
Each tool targets a unique aspect: database listing, table listing, schema details, ad-hoc queries, batch scripts, connection testing, and configuration changes. The two execute tools are clearly distinguished by single vs multi-statement batch execution.
All tools follow a consistent verb_noun pattern using lowercase snake_case, making the API predictable and easy to learn. No mixed conventions or vague verbs.
With 7 tools, the set is well-scoped for a SQL Server integration, covering essential operations without redundancy or bloat. It fits squarely in the ideal 3-15 range.
The tool set provides complete coverage for a SQL Server MCP: connection management, database/table discovery, schema inspection, and arbitrary SQL execution (both single statements and batch scripts). There are no obvious gaps that would cause agent failures.
