Highlights ✨

More and more agents are supporting Code Mode or Programmatic Tool Calling so we have added support for structured outputs and output schemas to help do this effectively.

These schemas are only advertised to clients advertising MCP 2026-07-28 spec support (or later). Our compound tools required some updates to allowed output schemas, so they are not valid for older clients and we don't return them.
