Beyond Claude for Excel: The Real Office AI Agent Stack for 2026

Anthropic has made Claude for Excel, Word, and PowerPoint generally available, but the article says the real shift is beyond single-app assistants.

The recommended model for 2026 is a layered office AI stack: in-app agents for simple tasks, MCP/connectors for cross-tool actions, and a governed workspace for multi-agent work.

That approach better matches how knowledge work actually happens across tools like Notion, Slack, Google Sheets, Linear, and Jira.

The key requirements are scoped access, context engineering, version history, and auditability so automation stays safe and reversible.
