Office Addin Mcp

Connects to Office add-ins running in WebView2 on Windows through Chrome DevTools Protocol, exposing workflow tools like excel.tabulateRegion, word.applyEdits, and outlook.draftReply instead of raw Office.js primitives. Each tool compresses what would normally take 5-20 API calls into a single round-trip. Ships a server-side query DSL that filters and aggregates inside the host, a document cache for zero-overhead repeated discovery, and MCP resources with live subscriptions to office:// URIs. Includes macro record/replay, auto-diagnostics on Office.js errors, and self-healing CDP reconnection. Reach for this when you want LLMs to drive Excel workbooks, Word documents, Outlook mail, PowerPoint decks, or OneNote pages without teaching the model how to chain Office.js calls manually.
