# The notion-query-database-view tool stops working

Calls to /mcp, MCP tool notion-query-database-view on Notion MCP stopped working on September 29, 2026.

On September 29, 2026, the notion-query-database-view tool was removed from the Notion MCP. Requests sent to /mcp using MCP tool notion-query-database-view fail since that date. Notion MCP noted that the tool is no longer available.

## What to use instead

Call notion-query-data-sources instead, using the same view_url with {"data": {"mode": "view", "view_url": "..."}}.
