postgres-mcp-server

postgres-mcp-server

这是一个 PostgresSQL 模型上下文协议服务，可让你的大模型与（本地）数据库交互。 警告：此项目仍处于实验阶段，因此请勿在真实数据库上使用，并谨慎执行写入查询！

前提条件

• 安装 nodeJS
• 运行 npm install 以安装项目依赖
• 设置以下环境变量：

DATABASE_NAME="your_database_name"
DATABASE_USER="your_database_user"
DATABASE_PASSWORD="your_database_password"
DATABASE_SCHEMA_name="your_database_schema_name" # i.e. standard this is usually `public`

在 VSCODE 的 settings.json 中进行简单配置：

{
  "chat.mcp.discovery.enabled": true,
  "mcp": {
    "postgresql-database": {
      "command": "npm",
      "type": "stdio",
      "args": ["start", "--prefix", "/path/to/code/postgres-mcp-server"],
      "env": {
        "CUSTOM_INSTRUCTIONS": "The databaseName is specific for the git branch we are on. It always has the same structure: jira_xxxxx, where the jira_xxxxx stands for the Jira ticket number. This Jira ticket number we always use at the start of a git branch. Hence, you should be able to take this from the current branch and create the databaseName from it",
        "DATABASE_NAME": "my-database-name",
        "DATABASE_USER": "my-user",
        "DATABASE_PASSWORD": "my-password",
        "DATABASE_SCHEMA_NAME": "public"
      }
    }
  }
}
