Install MCP Toolbox for Databases

No one-line setup: it needs a build step, an app plugin or account details. Follow the README, then add it to your client the way the MCP setup guide shows for Claude Code, Claude Desktop / claude.ai, ChatGPT, Cursor, VS Code and others.

Security notes

  • Connect it to a development database or a read-only user first: the model can run writes and deletes if the credentials allow them.
