What probably matters to youSection of the release

Unclear Whether the Design connector still gets its login token some other way.

What

MCP (Model Context Protocol) is the standard Claude Code uses to connect to outside tools. Claude Code can now create and check signed tickets for MCP tools running on a machine. Each ticket names one tool, is tied to one session, and is signed with a device key Claude Code keeps. A ticket is refused if the tool's name does not fit in it.

This takes the place of a helper that fetched a read-only login token for the Design MCP connector.

Why

It gives remote machine MCP tools a signed ticket that proves which tool and session a request belongs to.
