MCP viewer keyboard navigation now wraps at list boundaries, with arrow keys moving through every row and `Tab` / `Shift+Tab` moving between servers. --- The MCP viewer now lets users continue navigating at list boundaries instead of reversing direction. `Up` and `Down` wrap through every displayed row, including server headers and tools. `Tab` and `Shift+Tab` provide faster server-level navigation by moving to the next or previous server header and wrapping at either end. From a tool, `Shift+Tab` returns to that tool's server header, while `Tab` advances to the next server. This also makes header-only lists—such as when every server has an error—fully navigable with either set of keys.
