Bridges Claude to Excel add-ins running in WebView2 by connecting through the Chrome DevTools Protocol on port 9222. Forked from the official Chrome DevTools MCP and adapted for Office's embedded runtime. Ships with lifecycle tools that launch Excel, sideload your manifest, and spin up the dev server automatically, plus a full set of read-only inspection tools for workbooks, ranges, tables, pivot tables, charts, and conditional formats. Also exposes the underlying CDP for screenshots, console access, and network inspection. Built for Windows desktop Excel where WebView2 hosts the add-in taskpane. If you're building Office add-ins locally and want Claude to interact with live workbook state or automate your debugging workflow, this handles the connection layer.
