MCP servers are programs that give Claude extra tools. When Claude Code sets this server up, it can now add `--pane` to the options it starts the server with. Previously only `--preview` could be added.\n\n**Why**\n\nThis points to a new pane mode for the bundled test feature.\n\n- Area: Claude Test\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
