Questions

What is the Grain SQL MCP server?

Run SQL queries and inspect database schemas through safe, visible MCP tools. It is made by @pattrnlabs and listed in the official MCP Registry as io.github.pattrnlabs/grain. MCP (Model Context Protocol) is the open standard that lets AI apps like Claude, ChatGPT and Cursor use outside tools.

How do I add Grain SQL to Claude?

In Claude Code, run: claude mcp add grain -- npx -y grain-tools@0.10.44

How do I add Grain SQL to ChatGPT?

ChatGPT only connects to remote MCP servers, and Grain SQL runs on your own computer. Use it from Claude, Cursor or another app that runs local servers.

How do I add Grain SQL to Cursor?

Open Cursor settings, go to MCP, choose "Add new MCP server" (or edit ~/.cursor/mcp.json) and add: { "mcpServers": { "grain": { "command": "npx", "args": [ "-y", "grain-tools@0.10.44" ] } } }

Does Grain SQL work right now?

It runs on your own computer, so it works once you install it. There is no remote server for us to check.
