}Which one to pick
- Start with MCP Toolbox for Databases: it's maintained by Google and follows its API.
- A remote server (CockroachDB Cloud) 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 CockroachDB MCP server?+
Yes: MCP Toolbox for Databases and CockroachDB Cloud, maintained by Google.
How do I connect CockroachDB 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 CockroachDB 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 CockroachDB MCP server in ChatGPT?+
ChatGPT connects to remote MCP servers only. CockroachDB Cloud 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 CockroachDB?+
Start with the official server, a read-only or test account and approval prompts on for anything that writes. Content the agent reads from CockroachDB (tickets, messages, pages) can carry prompt-injection instructions, so don't auto-approve actions.
