SQL MCP Server

by t3ta
Verified

hybrid server

The server is able to function both locally and remotely, depending on the configuration or use case.

Integrations

  • Supports configuration via .env files for database credentials and connection settings

  • Includes CI/CD integration through GitHub Actions workflows

  • Provides testability with Jest for ensuring server reliability and performance

SQL MCP 服务器 (TypeScript)

该项目提供了模型上下文协议 (MCP) 服务器的TypeScript 实现,使语言模型和其他与 MCP 兼容的客户端能够在需要时通过 SSH 堡垒隧道查询 PostgreSQL 数据库。

它专为灵活性和安全的数据库访问而构建,支持具有只读事务的 AWS RDS,并使用基于 stdin/stdout 的通信,使其适用于本地、容器化或 AI 驱动的用例。

特征

  • 🔒 SSH 堡垒支持通过 SSH 隧道安全访问私有 RDS 实例
  • 🐘 使用pg库的 PostgreSQL 只读查询引擎
  • 📡 基于 STDIO 的 MCP 协议传输
  • 🧠 与memory-bank-mcp-server兼容
  • ⚙️ 可通过.env或环境变量轻松配置
  • 🧪 完全可以使用 Jest 和 mocks 进行测试

安装

克隆存储库并安装依赖项:

git clone https://github.com/your-org/sql-mcp-server.git cd sql-mcp-server npm install npm run build Configuration (Optional .env file) Create a .env file in the project root: DB_USER=postgres DB_PASS=yourpassword DB_HOST=localhost DB_PORT=5432 DB_NAME=mydatabase USE_SSH_TUNNEL=true SSH_BASTION_HOST=bastion.example.com SSH_BASTION_USER=ec2-user SSH_PRIVATE_KEY_PATH=~/.ssh/id_rsa Usage Run the server using npx: npx -y @modelcontextprotocol/server-postgres postgresql://<user>:<pass>@localhost:5433/<dbname> For direct connection without SSH tunneling, set the appropriate environment variables: DB_HOST=rds-host.amazonaws.com DB_PORT=5432 npx -y @modelcontextprotocol/server-postgres postgresql://<user>:<pass>@rds-host.amazonaws.com/<dbname> Sample Input { "type": "call_tool", "params": { "name": "query", "arguments": { "sql": "SELECT * FROM users LIMIT 10" } } } Sample Output { "content": [ { "type": "text", "text": "[{\"id\":1,\"name\":\"Alice\"}]" } ], "isError": false } ⸻ Related Docs • Architecture • Domain Models • Glossary • Coding Standards • Tech Stack • User Guide ⸻ License MIT ⸻ Contribution Guide We welcome community contributions!
