跳过安装。2 分钟内即可运行。
在 cloud.anythingmcp.com 开始免费试用,一键添加 PostgreSQL,然后将你的 AI 客户端(Claude、ChatGPT、Copilot 或 Cursor)指向生成的 MCP 端点。无需 Docker,无需 git clone,无需任何工程经验。
摘要
直接查询 PostgreSQL 数据库:列出表、描述列并运行只读 SQL。安装后为只读;凭证会加密保存,而不是放在连接字符串中。

PostgreSQL 的示例提示
点击任意提示即可复制,然后粘贴到 Claude、ChatGPT、Cursor、Gemini、Copilot 或 OpenClaw 中,在该连接器上运行。
Claude 是 AI,可能会出错。请核对回答。
💡 无需安装? 直接使用 cloud.anythingmcp.com。 登录、点击 Connectors → PostgreSQL、粘贴凭证、生成 MCP API key — 完成。无 Docker、无
git clone、无本地服务器。

设置
Setup
- Create a dedicated role for the agent and grant it only what it needs:
The last line matters: without it, tables created tomorrow are invisible.CREATE ROLE amcp_reader LOGIN PASSWORD 'change-me'; GRANT CONNECT ON DATABASE sales TO amcp_reader; GRANT USAGE ON SCHEMA public TO amcp_reader; GRANT SELECT ON ALL TABLES IN SCHEMA public TO amcp_reader; ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO amcp_reader; - Set
POSTGRES_HOST,POSTGRES_PORT(5432),POSTGRES_DATABASE,POSTGRES_USERandPOSTGRES_PASSWORD.
…(continued in the in-app connector instructions)
前提条件: POSTGRES_HOST, POSTGRES_PORT, POSTGRES_DATABASE, POSTGRES_USER, POSTGRES_PASSWORD
本地安装连接器
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
打开 http://localhost:3000/connectors/store,选择 PostgreSQL 并填入前提条件中列出的环境变量。
