Published artifacts can now declare Claude's own browser tools as a host MCP server.

The Artifact tool's prompt text for host MCP servers now documents a built-in exception, host:claude_browser, which lets a published Artifact declare the Claude desktop app's own browser tools — read_page, get_page_text, find, preview_start, navigate, computer, and form_input — as a host server. Previously only user-configured local MCP servers could be declared this way.
