Microsoft Copilot (Microsoft 365)
Federated Copilot Connectors will support write, update and delete actions

Federated Copilot connectors (MCP type) currently let Microsoft 365 Copilot read data from third-party services in real time. With this update, the connector tools that create, update, and delete content in those services are unblocked in Copilot Chat, so users can complete work without leaving Copilot. Copilot acts with the user's own account and permissions at the third-party service, and every create, update, or delete action requires the user's explicit confirmation before it runs. Admins can view each connector's read and write/delete tools in the Microsoft 365 admin center and disable connectors that don't meet their organization's policies.
