WebKitUI MCP 0.6.6 Developer Preview improves native confirmation keyboard handling on Apple-silicon Macs running macOS 15 or later.
- Confirmation takes keyboard focus without a bouncing executable icon. Escape and Return cancel only after the initial delay; Tab and Space remain usable, including in the optional none mode.
- Malformed resume requests no longer consume a one-use handoff token.
- The confirmation helper inherits only the environment values it needs.
- Safari compatibility reports its actual limitation: finish restricted authentication workflows manually in Safari; this does not transfer control or the session back to the MCP.
- Release checks now cover embedded executables, source provenance and incomplete test runs.
