功能特性
- 支持 MySQL 和 PostgreSQL 数据库
- 提供表结构信息作为资源
- 支持只读 SQL 查询执行
- 使用事务确保查询安全性
安装
使用 cnpm 进行安装:
git clone <repository-url>
cd mcp-server-db-ts
cnpm install
配置
- 复制
.env.example文件为.env:
cp .env.example .env
- 编辑
.env文件,设置您的数据库连接信息:
# 数据库连接配置

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
