Onlyoffice MCP: your collaboration rooms in Claude or ChatGPT

Onlyoffice's MCP server connects your AI app to Onlyoffice, which describes it as a room-based collaborative platform. ContextGate connects it to Claude, ChatGPT and Cursor through your Onlyoffice sign-in. The full tool list appears after you connect, so you can see exactly what it does with your rooms and switch off anything you don't want an AI app to change.
