Cursor CLI Jan 8: Model Selection, MCP Controls, 10x Hooks

TL;DR

• New agent models command and /models slash command for quick model switching
• Hooks execution latency cut by 10x with parallel execution
• MCP server management and rules/commands editing now available in CLI
• Breaking: Ctrl+D now requires double-press to exit (standard shell behavior)

New

• Model list and selection — Use agent models, --list-models, or /models to list available models and switch between them instantly.
• MCP server management — Enable and disable MCP servers on the fly with /mcp enable and /mcp disable commands.
• Rules and commands editing — Create and edit rules with /rules and commands with /commands directly from the CLI.
• Auto-named tabs — Tabs are now automatically named based on chat content.
• Subcommand history — Executed subcommands are now recorded in command history.
• MCP names with spaces — All /mcp commands now support server names containing spaces.
• New primary entrypoint — agent is now the main CLI command; cursor-agent remains as a backward-compatible alias.

Fixed

• Hooks performance — Hooks now execute in parallel with merged responses; latency reduced by 10x.
• afterFileEdit hook — Now correctly provides old_string with the file's previous content for proper diff capture.
• Ghost line rendering bug where deleted lines left visual artifacts.
• Race condition where conversation state could be overwritten during turn completion.
• "Cannot find module" error related to node-pty on some platforms.
• Chat name generation issues.
• Several bugs with follow-up messages.

Breaking Changes

• Ctrl+D behavior — Now requires double-press to exit (standard shell behavior). Single press no longer exits.
• Shift+Enter behavior — Now inserts a newline instead of submitting; use Enter alone to submit multi-line prompts.
