DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.196

Claude Preview MCP Integration

A new recognized MCP server named "Claude Preview" is now integrated, giving it first-class treatment alongside "Claude in Chrome". Tools under the mcp__Claude_Preview__ namespace require explicit permission via the standard allow/deny flow and display the message "Claude Preview requires permission."

Details
  • Server name normalized via the same slug mechanism as other first-party MCPs.
  • Permission prompt includes metadata about the Chrome origin-consent flag.
  • The server name set that receives special handling now includes "claude-in-chrome", "Claude in Chrome", and "Claude Preview".
Evidence

New MCP integration (search for "Claude Preview" and "mcp__Claude_Preview__")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
