Google Antigravity + GoldRush
by GoogleIDE
Standalone
Quick Start
1
Install Google AntigravityDownload Antigravity from antigravity.google and open your project. Free during public preview for macOS, Windows, and Linux.
2
Install GoldRush CLIQuery onchain data directly from your terminal, useful for testing queries before using them in Antigravity.
npm install -g @covalenthq/goldrush-cli
3
Add GoldRush MCP ServerOpen the MCP Store via the "..." dropdown in the agent panel, search for GoldRush, and click Install. Or add it manually to your
mcp_config.json.{
"goldrush": {
"command": "npx",
"args": ["-y", "@covalenthq/goldrush-mcp-server"],
"env": { "GOLDRUSH_API_KEY": "YOUR_API_KEY" }
}
}4
Open the Antigravity chat panelUse the built-in Gemini chat or the Manager view for parallel agent tasks.
5
Start querying onchain dataAsk: "Use the GoldRush MCP tools to get token balances for vitalik.eth on Ethereum and Base"
Example Prompts
“Get the ETH balance for this wallet address”
“Show me recent transactions for this address on Base”
“Generate a GoldRush SDK client with typed balance methods”
“Add an API route that returns NFT holdings for a wallet”
“Create a React hook that fetches token prices from GoldRush”
“Use the Manager to analyze this wallet across 5 chains in parallel”
“Build a TypeScript utility for multi-chain balance aggregation”
“Refactor this component to use the GoldRush SDK instead of raw fetch”
Available MCP Tools (27)

Available skills
Foundational APIREST endpoints for historical blockchain data. Balances, transactions, NFTs, token prices, security checks, cross-chain queries across 100+ networks.
Streaming APIReal-time GraphQL subscriptions. OHLCV candles, new DEX pairs, wallet activity monitoring, token search, and PnL queries via WebSocket.
x402Pay-per-request access without API keys. Agents pay with stablecoins using the HTTP 402 protocol. No accounts, no rate limits, no key management.
CLITerminal-first blockchain data with native MCP support. 17 commands that work for both humans and AI agents.
Common Workflows
Parallel Multi-Chain Analysis
1Open the Manager view in Antigravity
2Assign separate agents to fetch data from different chains via GoldRush MCP
3Each agent queries balances, transactions, or pricing independently
4Review the aggregated results in a single workspace
Build a Web3 Feature
1Open a component file and start a Gemini chat session
2Ask Antigravity to add GoldRush balance fetching with the MCP tools
3It generates the integration with typed imports and error handling
4Use the built-in browser to test the live output
Full-Stack Debugging with Onchain Data
1Open the built-in browser alongside your code
2Ask Antigravity to debug a failing blockchain query
3It uses GoldRush MCP tools to compare expected vs actual API responses
4Apply the fix and verify in the integrated browser
Migrate to GoldRush
1Ask Antigravity to analyze your current blockchain data layer
2It plans a migration from raw RPC calls to the GoldRush SDK
3Antigravity generates multi-file changes with proper typing
4Review the diff and accept the coordinated migration
Tips for Success
Use the MCP Store for one-click GoldRush server installation instead of manual config
The Manager view is ideal for multi-chain tasks — assign one agent per chain
Use the built-in browser to visually verify blockchain UI as you build

.agents/skills/ for team reuseGoogle Antigravity FAQ
Open the MCP Store via the "..." dropdown in the agent panel and search for GoldRush, or manually add the server configuration to your
mcp_config.json file. Both approaches connect GoldRush tools to the Gemini agent.Troubleshooting
MCP Server not appearing in AntigravityRestart Antigravity after adding the MCP configuration. Check the MCP panel to verify the server status shows as connected. Ensure
npx is available in the integrated terminal.Antigravity not using GoldRush toolsExplicitly mention 'use the GoldRush MCP tools' in your prompt. Gemini may need a direct reference to prefer MCP tools over general web search.
Slow responses when using MCPMCP tool calls add latency as they make live API requests. For faster iteration, ask Antigravity to generate code with the SDK instead of making live calls during development.
