Notion MCP now supports databases with multiple data sources

📌 Context

Notion introduced support for databases with multiple data sources in late 2025. Until now, the Dust Notion MCP server was using an older Notion API version that couldn't access these databases, limiting functionality for users who had adopted this new Notion feature.

🔄 Impact on Dust

We've updated the Notion MCP server to use the newest Notion API version and adapted it to support databases with multiple data sources. This enhancement ensures that your agents can now query and interact with these advanced Notion databases without restrictions.

👤 Impact for you

If you use the Notion MCP tool: You can now seamlessly access and work with Notion databases that use multiple data sources. No more errors or missing data when your agents query these databases.

If you use the Notion Connector: This update does not apply to the Notion Connector, which still doesn't support databases with multiple data sources. There is currently no ETA for adding this capability to the Connector.

✅ Actions required

No action required on your part. If you use the Notion MCP tool with databases containing multiple data sources, they will now work automatically. You can start using this capability immediately with your existing agents.
