Spreadsheet DB is a Model Context Protocol (MCP) server: SQLite-authoritative entity database with an async Google Sheets projection for AI agents. Because it speaks the Model Context Protocol, AI assistants can use Spreadsheet DB as a set of callable tools instead of you copy-pasting between apps.
It runs locally: the npm package spreadsheet-db-mcp speaks MCP over stdio on your machine. The current release is v0.1.1, published under the MIT license, with source at ManddarinShop/Hikoutei on GitHub.
On mcp.site, Spreadsheet DB sits in the Database category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
