Antigravity is Google’s agent-first development platform — desktop app, CLI, and SDK for multi-agent orchestration. The integrations below are complementary — use any combination.
Migrating from Gemini CLI? Antigravity CLI is its direct successor.
The setup below works for both the desktop app and CLI.

​
Setup

1

Install the SKILL

Gives Antigravity built-in knowledge of the CoinGecko API — writes correct requests without manual prompting.Clone into Antigravity’s skills directory:
git clone https://github.com/coingecko/skills.git .agent/skills/coingecko
Antigravity loads the skill automatically when it detects a CoinGecko-related task.
Full details: Agent SKILL
2

Add CoinGecko API MCP

Connects Antigravity to live CoinGecko data — prices, market caps, onchain pools, OHLCV, NFTs, and more.Open ⋯ → MCP Servers → Manage MCP Servers → View raw config to edit ~/.gemini/antigravity/mcp_config.json:
Add the CoinGecko MCP:
"coingecko": {
  "serverUrl": "https://mcp.api.coingecko.com/mcp",
  "disabled": false
}
Save and reload the MCP panel.

3

Add Docs MCP

Lets Antigravity search CoinGecko documentation directly — endpoint references, guides, and tutorials.Add to the same config:
"coingecko-docs": {
  "serverUrl": "https://docs.coingecko.com/mcp",
  "disabled": false
}
Full details: Docs MCP

​
SDK Prompts

Copy the prompt into one of Antigravity’s rules files:
FileScope
AGENTS.md in project rootProject-level — also read by Cursor, Claude Code, and Codex
~/.gemini/AGENTS.mdGlobal — all projects
GEMINI.md in project rootAntigravity-only, takes precedence over AGENTS.md

Prompt for integrating CoinGecko Python SDK

​
Try It Out

Once everything’s wired up, try asking Antigravity:
  • “Using the CoinGecko MCP, show me the top 10 trending pools on Base and export them to CSV.”
  • “Write a Python script using coingecko-sdk that tracks my portfolio and alerts if any coin moves more than 10% in an hour.”
Use Antigravity’s Manager view to run agents in parallel — spawn one agent per chain to compare onchain activity across Base, Solana, and Ethereum simultaneously.
