What is the Etherscan MCP Server?

Connect your Etherscan API key to any AI agent and gain instant access to on-chain data across Ethereum and other EVM-compatible networks through natural conversation.

What you can do

Native Balances — Retrieve the native token balance (ETH, MATIC, etc.) for single or multiple addresses (up to 20) using get_balance and get_balance_multi.
Transaction History — Fetch comprehensive lists of normal and internal transactions for any wallet address with get_tx_list and get_tx_list_internal.
Token Tracking — Monitor transfers for ERC-20, ERC-721 (NFTs), and ERC-1155 tokens using specialized tools like get_token_tx and get_token_nft_tx.
Multi-Chain Support — Query data across different networks by specifying the chainid (e.g., 1 for Ethereum, 137 for Polygon).
Granular Filtering — Filter transaction results by block range, pagination, and sort order to find exactly what you need.

FAQ

Frequently asked questions

How can I check the balance of multiple Ethereum addresses at once?

You can use the get_balance_multi tool. Provide the chainid (e.g., 1 for Ethereum) and a comma-separated list of up to 20 addresses to retrieve all balances in a single request.

Can I track NFT transfers for a specific wallet?

Yes! Use the get_token_nft_tx tool. By providing the wallet address and the appropriate chainid, the agent will list ERC-721 transfer events associated with that account.

Does this support networks other than Ethereum Mainnet?

Yes, as long as you use the correct chainid. For example, use 1 for Ethereum, 137 for Polygon, or 10 for Optimism, provided your API key has access to those Etherscan-equivalent explorers.

How does the Vercel AI SDK connect to MCP servers?

Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
