What is Google Antigravity IDE?

Antigravity is Google's free AI-native IDE that integrates Gemini 3.1 Pro for code generation, debugging, and deployment. It's in preview and competes directly with Cursor.

Does Google Antigravity support MCP?

No. As of April 2026, Antigravity does not support MCP (Model Context Protocol) servers. This is a significant limitation for teams relying on MCP integrations for tools like Figma, Amplitude, or custom enterprise plugins. Cursor has a mature MCP marketplace.

Which is better, Cursor 3 or Antigravity?

Cursor 3 is better for professional developers who need MCP plugins, multi-model support, and a mature ecosystem. Antigravity is better for Google ecosystem users and those wanting a free AI IDE with strong Gemini integration.

Last verified: April 2026

Quick Comparison

Feature	Cursor 3	Google Antigravity
Price	$20/mo (Pro)	Free (preview)
AI Model	Multi-model (Claude, GPT, Gemini)	Gemini 3.1 Pro
MCP Support	✅ Mature marketplace	❌ Not supported
Base	VS Code fork	Custom (Google)
Composer	Composer 2 (multi-file agent)	Built-in agentic mode
Context	Large (project-wide)	Large (Gemini 2M tokens)
Deployment	Manual / CI	Google Cloud integrated
Best for	Professional devs	Google ecosystem

Cursor 3 Strengths

Multi-model support — Use Claude Opus 4.6, GPT-5.4, or Gemini depending on the task
Composer 2 — Advanced multi-file agentic editing with background agents
MCP marketplace — Hundreds of plugins for Figma, databases, APIs, etc.
VS Code ecosystem — All your existing extensions work
Privacy mode — Code stays on your machine
Mature — Established tool with large community and extensive documentation

Google Antigravity Strengths

Free — No cost during preview
Gemini 3.1 Pro native — 2M token context window
Google Cloud integration — Deploy directly to GCP
AI Studio connection — Prototype with AI Studio, code in Antigravity
Google ecosystem — Works with Firebase, Cloud Run, etc.

The MCP Gap

The biggest differentiator right now is MCP support. Cursor’s MCP marketplace lets you connect to databases, design tools, project management, and custom APIs. Antigravity has none of this.

For teams that rely on MCP integrations, this is a dealbreaker for Antigravity — at least until Google adds support.

Who Should Use What

Scenario	Pick
Professional team	Cursor 3 (MCP + multi-model)
Google Cloud projects	Antigravity (native integration)
Budget-conscious	Antigravity (free)
Multi-model needs	Cursor 3
VS Code extensions	Cursor 3
Learning to code	Either (both good for beginners)
