}Which one to pick
- Start with MCP Toolbox for Databases: it's maintained by Google and follows its API.
- A remote server (Cloud SQL) needs no install and signs you in with OAuth. It's also the only kind ChatGPT and claude.ai can use.
FAQ
Is there an official Cloud SQL MCP server?+
Yes: MCP Toolbox for Databases and Cloud SQL, maintained by Google.
How do I connect Cloud SQL to Claude?+
In Claude Code, run the claude mcp add command shown above. In Claude Desktop, add the server to claude_desktop_config.json (Settings > Developer > Edit Config) and restart the app.
How do I use the Cloud SQL MCP server in Cursor or VS Code?+
Open the Cursor or VS Code tab on the server above: it has the exact mcp.json entry. The same server also works in Claude Code, Claude Desktop / claude.ai, ChatGPT, Cursor, VS Code and Codex.
Can I use the Cloud SQL MCP server in ChatGPT?+
ChatGPT connects to remote MCP servers only. Cloud SQL has a hosted URL: at chatgpt.com/plugins choose + > Add custom MCP server, paste the URL and create it as a plugin.
Is it safe to give an AI agent access to Cloud SQL?+
Start with the official server, a read-only or test account and approval prompts on for anything that writes. Content the agent reads from Cloud SQL (tickets, messages, pages) can carry prompt-injection instructions, so don't auto-approve actions.
