WorkbookAPI

Overview

WorkbookAPI is a Model Context Protocol server that lets you check and calculate local Excel workbooks with AI agents while keeping your files on your machine. It exposes spreadsheet operations as tools that Claude, Cursor, VS Code, and other AI assistants can invoke directly, bringing computational power to your Excel workflows without uploading data anywhere.

The server runs entirely locally via the npm package workbookapi-mcp, speaking MCP over stdio. Installation is simple with npx -y workbookapi-mcp, and no authentication or external credentials are required—it works immediately out of the box. The latest release is v0.1.1.

WorkbookAPI appears in the File System category on mcp.site and integrates with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this project for workbookapi.com, claim this listing to verify ownership and keep the details up to date.
