Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00067 | $0.02194 |
| Opus 5 | $0.00034 | $0.01097 |
| Sonnet 5 | $0.00013 | $0.00439 |
| Haiku 4.5 | $0.00007 | $0.00219 |
Grade A, and why
db-mcp-server scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

数据库 MCP 工具使用指南
🎯 核心原则
- 先查连接，再操作 — 不知道
connection_id时必须先调mcp__dbmcp__list_connections，禁止猜测 ID - 逐层探索 — 按
list_connections→list_databases→list_tables→describe_table的顺序探索 - 只读优先 — 查询用
mcp__dbmcp__execute_query，写入/DDL 用mcp__dbmcp__execute_sql（需确认权限） - 默认数据库 — 大部分工具的
database参数可选，不传则使用连接的默认数据库 - 明确告知 — 每次操作后向用户说明
connection_id、database、工具名称；若返回 OSS 链接须给出可点击地址 - 大表慎用 —
execute_query必须带LIMIT；文档/ER 库表过多时优先 markdown 或include_columns: false
支持的数据库类型：mysql、postgresql
🔧 可用工具列表（22 个）
所有工具名前缀为 mcp__dbmcp__，例如：mcp__dbmcp__list_connections
基础探索工具
| 工具 | 用途 | 必需参数 | 示例 |
|---|---|---|---|
list_connections |
列出所有可用数据库连接 | 无 | {"search": "mysql"} |
list_databases |
列出指定连接的数据库 | connection_id |
{"connection_id": 1} |
list_tables |
列出指定数据库的表 | connection_id |
{"connection_id": 1, "database": "mydb"} |
list_views |
列出视图 | connection_id |
{"connection_id": 1} |
list_procedures |
列出存储过程 | connection_id |
{"connection_id": 1} |
describe_table |
查看表结构（字段、类型、键） | connection_id, table |
{"connection_id": 1, "table": "users"} |
查询与执行工具
| 工具 | 用途 | 必需参数 | 权限 |
|---|---|---|---|
execute_query |
执行 SELECT 查询（只读） | connection_id, sql |
读 |
execute_sql |
执行任意 SQL（DDL/写入） | connection_id, sql |
写/DDL |
⚠️ 重要提示：
execute_query只能执行 SELECT/SHOW/DESCRIBE/EXPLAIN 等只读语句execute_sql可以执行 INSERT/UPDATE/DELETE/CREATE/DROP/ALTER 等语句，需要相应权限- 所有 SQL 查询必须带 LIMIT，避免返回大量数据
文档与图表工具
| 工具 | 用途 | 必需参数 | 特色功能 |
|---|---|---|---|
export_db_doc |
导出数据字典文档 | connection_id |
支持 markdown/pdf，可上传 OSS |
generate_er_diagram |
生成 ER 图 | connection_id |
业务域分析 + Mermaid 图，支持 pdf/markdown |
generate_data_flow |
生成数据流图 | connection_id |

export_ddl |
导出完整 DDL | connection_id |
包含表、视图、存储过程、触发器 |
📊 输出格式选项：
format: "markdown"- Markdown 文本（适合预览和编辑）format: "pdf"- PDF 文件（需要服务器安装中文字体）upload_to_oss: true- 上传到对象存储并返回下载链接
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

db-mcp-server is a skill published in the GitHub repository redgreat/db_mcp_server (2 stars, last pushed 2d ago), licensed MIT. It adds 67 tokens to every session and 2,194 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
