Connect aNewStream to Antigravity

Vibe coding meets product ops.

Published: 2026-02-04

TL;DR

Antigravity is Google's AI IDE built for vibe coding - staying in flow while AI handles the details. Connect aNewStream via MCP and your product changelog updates without breaking that flow. No context switching. No Alt-Tab dance.

Why Antigravity?

Antigravity eliminates context switching. The IDE is designed to keep you in flow state.

Before MCP, AI agents could only see your open files. Now they can access:

All without leaving the editor.

The Problem MCP Solves

Traditional workflow:

  1. Code a feature
  2. Alt-Tab to browser
  3. Open your changelog tool
  4. Write the update
  5. Alt-Tab back to IDE
  6. Try to remember where you were

With aNewStream + Antigravity:

  1. Code a feature
  2. Say "log that I added dark mode to WIDGET-001"
  3. Keep coding

No context switch. Flow preserved.

Setup

Step 1: Open Antigravity Settings

Navigate to Settings > MCP Servers

Step 2: Add aNewStream

Add a new MCP server with:

{
  "name": "anewstream",
  "command": "node",
  "args": ["/path/to/aNewStream-01-agents/mcp/index.js"]
}

Or use the HTTP endpoint:

{
  "name": "anewstream",
  "url": "https://api.anewstream.com/mcp",
  "auth": {
    "type": "bearer",
    "token": "ansk_your_key_here"
  }
}

Step 3: Restart Antigravity

The MCP server connects automatically.

Vibe Coding Workflow

Here's how it feels in practice:

You're in flow, building a feature...

[Coding intensely]

You: Done with the auth system. Log MYAPP-001 update: added OAuth with Google and GitHub

Antigravity: Update #3 pushed to MYAPP-001

[Continue coding without breaking stride]

Later, you need context...

You: What was the pricing for MYAPP when we launched?

Antigravity: [Queries changelog]
  MYAPP-001 v1 (Jan 15): Launched at $29/month
  MYAPP-001 v4 (Feb 1): Increased to $39/month

No browser tabs. No switching apps. Just flow.

What "No Context Switching" Means

Old Way With MCP
Alt-Tab to changelog app Stay in IDE
Copy-paste feature description Natural language command
Search for old pricing "What was the price in January?"
Open browser for docs "Generate a changelog for MYAPP"

The AI pulls everything it needs through MCP.

Example Session

You: Create a product called FLOWSTATE for my new productivity app

Antigravity: Created product "FLOWSTATE"

[30 minutes of focused coding]

You: Push update to FLOWSTATE-001 - added focus timer with customizable durations

Antigravity: Update #1 pushed

[More coding]

You: Another update - FLOWSTATE-001 - added break reminders with notification sounds

Antigravity: Update #2 pushed

[End of session]

You: Summarize what I shipped today for FLOWSTATE

Antigravity: Today you added:
• Focus timer with customizable durations
• Break reminders with notification sounds
