How to Set Up and Use GoldRush
GoldRush MCP Server exposes Covalent's GoldRush blockchain data APIs as MCP tools and resources, giving AI assistants access to comprehensive on-chain data across 200+ blockchain networks. It covers token balances, transaction histories, NFT ownership, gas estimates, historical portfolio values, DEX spot prices, smart contract event logs, and multi-chain wallet activity including Bitcoin HD and non-HD addresses. Developers building blockchain analytics tools, portfolio trackers, or DeFi research workflows can connect Claude or other MCP clients directly to live chain data using a single GoldRush API key.

API calls return 401 Unauthorized
Verify your GOLDRUSH_API_KEY is correctly set in the MCP config env block. Test it directly: curl -H 'Authorization: Bearer YOUR_KEY' 'https://api.covalenthq.com/v1/chains/' to confirm the key is valid.
npx fails to download the package or times out
Check your internet connection and npm registry access. Try running 'npx -y @covalenthq/goldrush-mcp-server@latest --help' manually in a terminal to confirm npx can fetch and run the package.
Chain name errors when querying specific networks
Use the exact GoldRush chain name format (e.g. 'eth-mainnet', 'matic-mainnet', 'bsc-mainnet'). Ask Claude to 'list all supported chains' using the config://supported-chains resource to see the full list of valid chain names.
