Integrate GoldRush with your favorite AI coding agents.

Onchain data for your AI coding agent

Connect Claude Code, Codex, Cursor, GitHub Copilot and 9 other agents to GoldRush through the MCP server, Agent Skills or the SDKs. Your agent can then read balances, transactions, prices and DEX activity on 100+ chains.

The GoldRush MCP server

A Model Context Protocol server with 37 tools for onchain data and protocol analytics. It runs locally through npx with your API key, and any agent that speaks MCP can call it. Add the config on the right to Cursor, Windsurf, Cline or any other MCP client.

GoldRush Agent Skills

Agent Skills give your agent the context it needs for every GoldRush endpoint: parameters, response shapes and credit costs. One command installs all of them.

npx skills add covalenthq/goldrush-agent-skills

  • Foundational API

    REST endpoints for historical blockchain data. Balances, transactions, NFTs, token prices, security checks, cross-chain queries across 100+ networks.

  • x402

    Pay-per-request access without API keys. Agents pay with stablecoins using the HTTP 402 protocol. No accounts, no rate limits, no key management.

  • CLI

    Terminal-first blockchain data with native MCP support. 17 commands that work for both humans and AI agents.

import { GoldRushClient } from "@covalenthq/client-sdk";

const client = new GoldRushClient("YOUR_API_KEY");

const chains = ["eth-mainnet", "base-mainnet", "matic-mainnet"];
const wallet = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045";

const portfolio = await Promise.all(
    chains.map(chain =>
        client.BalanceService
            .getTokenBalancesForWalletAddress(chain, wallet)
    )
);

// Aggregate balances across all chains
const allTokens = portfolio.flatMap(r => r.data?.items ?? []);
const totalUSD = allTokens.reduce(
    (sum, token) => sum + (token.quote ?? 0), 0
);

Or let your agent write SDK code

For the app your agent is building, the GoldRush TypeScript SDK returns typed, decoded JSON, so there is no hex or ABI to parse. Ask for a portfolio tracker and you get code like this: balances on three chains, summed in USD.
