Copilot CLI v0.0.407-0: MCP Config & Mode Cycling

TL;DR

• Workspace-local MCP configuration via .vscode/mcp.json — no more global setup
• Tab/Shift+Tab now cycle through modes; shell is now a mode
• MCP servers with Microsoft OAuth configure automatically
• Multiple UX fixes: Ctrl+P for slash commands, terminal title on all TTYs, Windows slash flags no longer treated as paths

New

• GPT-5.3-codex support — added as a model option
• Workspace-local MCP configuration — define MCP servers in .vscode/mcp.json instead of global config

Improved

• MCP OAuth auto-configuration — Microsoft OAuth servers now configure automatically without manual client ID setup
• Mode cycling — Tab cycles forward, Shift+Tab backward; shell is now a mode alongside others
• Slash command input — Ctrl+P runs slash commands while preserving input (replaces Ctrl+X → /)
• Terminal title support — works on all TTY terminals, not just select few
• CI environment handling — auto-update disabled by default in CI
• Terminal tab display — shows session title when idle
• ask_user tool — now asks one question at a time for clearer interaction

Fixed

• Skill changes — changes from /skills commands take effect immediately
• /session usage string — only shows available subcommands
• Slash command newlines — commands taking prompts now work when immediately followed by newline
• Status bar characters — removed unintended characters
• Autopilot with custom agents — works with agents that specify explicit tools
• File descriptor leaks — updated node-pty to fix leaks
• Windows slash flags — dir /B no longer treated as file paths
• Diff mode flickering — eliminated when navigating files
• MCP enable/disable errors — show clear error when server name doesn't exist

Update: npm install -g @github/copilot-cli@0.0.407-0
