Antigravity is Google’s agent-first development platform — a standalone desktop app, CLI, and SDK built for multi-agent orchestration. Launched as Antigravity 2.0 at Google I/O 2026, it ships with Gemini 3.1 Pro by default and also supports Claude Sonnet/Opus 4.6 and GPT-OSS 120B. Plug CoinGecko in through any combination of the three integrations below — they’re complementary, not exclusive.
Migrating from Gemini CLI? Antigravity CLI is its direct successor (consumer Gemini CLI access ends June 18, 2026). The setup below works identically for the Antigravity desktop app and the new Antigravity CLI.

​
1. Install the SKILL

Give Antigravity built-in knowledge of the CoinGecko API so it writes correct requests without you pasting reference docs into every session. Antigravity loads Skills from a dedicated directory. Clone the CoinGecko Skills repo directly into your project’s skills folder: 
git clone https://github.com/coingecko/skills.git .agent/skills/coingecko
The cloned directory becomes .agent/skills/coingecko/SKILL.md — the directory-scoped format Antigravity expects. Antigravity loads the Skill automatically when it detects a CoinGecko-related task. Full instructions: SKILL docs.

​
2. Add the MCP Server

Connect Antigravity to live CoinGecko data — prices, market caps, onchain pools, OHLCV, NFTs, and more.
Antigravity Ide Coingecko Mcp
Open the MCP config via Additional options (⋯) in the Agent pane → MCP Servers → Manage MCP Servers → View raw config. This opens ~/.gemini/antigravity/mcp_config.json. Append the CoinGecko server: 
{
  "mcpServers": {
    "coingecko_mcp": {
      "serverUrl": "https://mcp.api.coingecko.com/mcp",
      "disabled": false
    }
  }
}
Save and reload the MCP panel. coingecko_mcp will appear under Available Tools in the Agent pane. Full instructions: MCP Server docs.

​
3. Add Rules

Rules are Antigravity’s persistent system instructions — loaded before every agent task. Add the CoinGecko SDK prompt rules so generated code follows the right auth, retry, and error-handling patterns. Copy the relevant rules and paste them into one of these files:
FileScope
AGENTS.md in project rootThis project only (recommended — also read by Cursor, Claude Code, and Codex)
~/.gemini/AGENTS.mdAll projects globally
GEMINI.md in project rootAntigravity-only, takes precedence over AGENTS.md
AGENTS.md is the cross-tool format — one file covers Antigravity, Cursor, Claude Code, and OpenAI Codex. Use GEMINI.md only if you need Antigravity-specific overrides.

​
What to try next

Once everything’s wired up, try asking Antigravity:
“Using the CoinGecko MCP, show me the top 10 trending pools on Base in the last 5 minutes and export them to CSV.”
“Write a Python script using coingecko-sdk that tracks my portfolio and sends me a Slack alert if any coin moves more than 10% in an hour.”
Antigravity 2.0’s Manager view lets you run agents in parallel — try spawning one agent per chain to compare onchain activity across Base, Solana, and Ethereum simultaneously.
