Cowork Antigravity

Claude Cowork & Antigravity Pool Integration

Overview

Reference guide and step-by-step instructions for connecting Claude Desktop, Claude Cowork, or Cockpit tools to an OpenAI-compatible Antigravity Pool API (inf_quota).

Prerequisites

• Running Antigravity Pool instance (default: http://localhost:8000)
• Valid API_KEY configured on the pool server
• Claude Desktop or Cowork application

Recommended Model Configurations

Claude Desktop Configuration

Add the custom endpoint to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "api_endpoint": "http://localhost:8000/v1",
  "api_key": "YOUR_POOL_API_KEY",
  "default_model": "claude-cowork"
}

Or via environment variables when launching Claude Desktop / Cowork:

export ANTHROPIC_BASE_URL="http://localhost:8000/v1"
export ANTHROPIC_API_KEY="YOUR_POOL_API_KEY"

Troubleshooting & Verification

1. Verify Pool Health:

   curl http://localhost:8000/health
   

   Ensure "ok": true and "accounts" count > 0.

2. Verify Models List:

   curl http://localhost:8000/v1/models -H "Authorization: Bearer YOUR_POOL_API_KEY"
   

   Check that claude-cowork and claude-combo are present in the returned list.

3. 429 Handling: The pool automatically failovers exhausted accounts silently. If multiple consecutive accounts hit rate limits, 429 dampening protects the pool from cascading lockouts.
