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.
npx agentmods add instructions/pixel2012/mcp-database-server/agents-mdgit clone --depth 1 https://github.com/pixel2012/mcp-database-serverWhat it costs to keep this loaded
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 | $0.01821 | $0.01821 |
| Opus 5 | $0.00911 | $0.00911 |
| Sonnet 5 | $0.00364 | $0.00364 |
| Haiku 4.5 | $0.00182 | $0.00182 |
Grade A, and why
mcp-database-server AGENTS.md 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MCP Database Server — AI 助手指南
项目概述
这是一个基于 Model Context Protocol (MCP) 的数据库服务器,通过 MCP 工具和资源接口让 AI 客户端(如 Claude)与多种数据库交互。
- npm 包名:
@executeautomation/database-server(或发布为@pixel2012/mcp-database-server) - GitHub: https://github.com/pixel2012/mcp-database-server
- 入口文件:
src/index.ts→ 编译为dist/src/index.js - MCP SDK:
@modelcontextprotocol/sdkv1.9.0 - 许可: MIT
构建与运行
| 命令 | 用途 |
|---|---|
npm run build |
编译 TypeScript |
npm run dev |
编译并立即运行 |
npm run watch |
监听模式编译 |
npm run clean |
删除 dist/ |
npm run example |
运行示例脚本 |
部署方式
本地直接运行
node dist/src/index.js <sqlite-path>
node dist/src/index.js --mysql --host <host> --database <db> --user <user> --password <pass>
集成到 mcp-gateway / Claude Desktop
方式一:本地路径(适合开发调试)
{
"mcpServers": {
"mysql-db": {
"command": "node",
"args": [
"/absolute/path/to/mcp-database-server/dist/src/index.js",
"--mysql", "--host", "10.60.5.47",
"--database", "dify_db", "--port", "3306",
"--user", "root", "--password", "xjgc@1234"
]
}
}
}
方式二:发布到 npm(推荐,启动快有缓存)
# 修改 package.json 中的 name 字段后发布
npm publish
{
"command": "npx",
"args": ["-y", "@yourname/mcp-database-server", "--mysql", ...]
}
方式三:GitHub 直拉(推代码即用,无需发布)
{
"command": "npx",
"args": ["-y", "github:pixel2012/mcp-database-server", "--mysql", ...]
}
npx会自动 clone →npm install(触发prepare脚本自动npm run build)→ 运行。首次启动较慢,后续有缓存。
Docker 部署
docker build -t mcp-database-server .
docker run --rm -i mcp-database-server /path/to/database.db

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.

mcp-database-server AGENTS.md is an instructions file published in the GitHub repository pixel2012/mcp-database-server (0 stars, last pushed 1mo ago), licensed MIT. It adds 1,821 tokens to every session, about $0.0091 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 2026-08-31.
