Organizations, MCP HTTP Streamable and broader REST API

August 25, 2025

August 2025 release.

Superinterface keeps evolving. August brings new ways to organize your workspace, broader API coverage, and an upgraded MCP transport.

Organizations

Workspaces can now live inside organizations so multiple environments share one plan. Invite teammates to the organization to grant access to all of its workspaces. Organization API keys let you create workspaces and issue keys across the organization.

Broader REST API

Our REST API now covers avatars, functions, MCP servers, and workspaces. We also expanded existing endpoints, giving you more control over API keys and assistant settings.

MCP HTTP streamable transport

MCP servers can connect over a streamable HTTP transport. Define custom headers once and Superinterface forwards them on every request, so you can authenticate and send metadata alongside each stream.

Get started

Read the REST API docs and the MCP servers guide to dive deeper. We can’t wait to see how you use these updates—share your projects on X or LinkedIn.
