Cursor CLI: Powerful NEW AI Agentic Coder IS FAST! RIP Claude Code?

Cursor CLI Tool: A Comprehensive Summary

Key Concepts:

• Cursor CLI: A command-line interface for interacting with AI agents for coding tasks.
• AI Agents: Software entities designed to autonomously write, review, and modify code.
• Headless Operation: Running the CLI tool in environments without a graphical user interface.
• Real-time Steering: Directing the AI agent's actions during code generation.
• Agent MD/Custom Rules/MCPS: Mechanisms for defining and controlling agent behavior.
• Token Usage: A measure of the computational resources consumed by AI models.
• Opus 4.1, GPT-5: Specific AI models used for code generation.
• Next.js, Tailwind: Technologies used in the example application.

1. Introduction to Cursor CLI

Cursor has released the Cursor CLI tool, enabling users to interact with AI agents directly from the terminal. This allows for writing, reviewing, and modifying code using AI assistance. The CLI is currently in beta but offers features like using the cursor agent from the CLI, running it headlessly, working with the agent within the editor, or running multiple agents in parallel. It's suitable for automation, collaborative development, and AI-assisted code generation.

2. Key Features and Capabilities

• Review Agent Edits: Access diff edits, approve changes, tweak, or reject AI changes directly within the terminal.
• Real-time Steering: Direct the agent's next move while it's coding.
• Custom Rules: Set cursor rules directly within the terminal using Agent MD, custom rules, and MCPS.
• Model Access: Access state-of-the-art models directly within the CLI with a cursor subscription.
• IDE Integration: Use the CLI with preferred IDEs.
• Scripting and Automation: Write powerful scripts and automations directly within the terminal.

3. Head-to-Head Comparison: Cloud Code vs. Codeex vs. Cursor CLI

A comparison was conducted to build a Next.js app with Tailwind for chats and components for collecting and showcasing customer feedback.

• Cloud Code: Used Opus 4.1, delivered a working demo quickly but needed prompts for interaction. Used 33k tokens.
• Codeex (OpenAI): Failed to produce a working app after 30 minutes, even with GPT-5. Got stuck setting up Tailwind and had compilation errors. Used 102k tokens.
• Cursor CLI: Used GPT-5, was slower but produced the best generation. Delivered a functional interactive app with a minimal, clean design. Used 188k tokens.

Key Takeaway: While Opus 4.1 is capable, Cursor CLI combined with Opus 4.1 yields better generations than GPT-5 alone. Cursor CLI shows potential due to its output quality, but token usage needs optimization.

4. Getting Started with Cursor CLI

1. Installation: Install using the provided command in the terminal.
2. Path Setup: Add the CLI to your system's path.
3. Run Cursor Agent: Execute the cursor-agent command.
4. Sign In: Authenticate with your Cursor account in the browser. A free tier is available, but you need to bring your own API key.

5. Using the Cursor CLI

• Command Access: Press / to view available commands.
• Model Selection: Use the model command to choose between GPT models, Sonnet 4, or Cloud 4.1 Opus.
• Auto Run: Enable auto-run for autonomous code generation based on deployed agents.
• New Chat: Start a new chat with the new command.
• MCP and Rules: Define agent behavior using MCP JSON files and rules linked to the Cursor application path.

6. Demonstration: Building a Note-Taking App

A note-taking app with drag-and-drop UI and schedule tracking was requested. The CLI was instructed to add as many features as possible.

• The CLI used GPT-5 (due to tier limitations preventing Cloud 4.1 usage) to build a plan and deploy agents.
• The CLI scaffolded a browser-based app, showcasing features in real-time.
• The generated app included note-taking and schedule features.
• The output quality was considered amazing, with the app being built in one shot.
• The app had some formatting issues and incomplete features, but overall, it was a decent result.

7. Zapier Sponsorship

Zapier is sponsoring the video and promoting Zap Connect 2025, a free virtual event on September 25th from 12 to 6 PM ET. The event will feature AI workshops, automation secrets, and live Q&As. Speakers include Box CEO Aaron Levie.

8. Conclusion

Cursor's CLI tool is a valuable addition to the coding community. It's currently in beta and will be continuously improved. The tool offers great potential for AI-assisted coding, automation, and collaborative development.
