* New data-region in Europe. Change the MCP URL to <https://mcp-api-eu.unified.to>. Data accessed by the MCP will be transfered directly from the EU data-region of Unified.to.
* Added support to expand an integration's tool over all of its available API endpoints, and not just the unified API's endpoints, which expand the number of tools by an additional 12,979\. Use `&include_external_tools=true`.

### [August 7, 2025](#august-7-2025)
