What the Etherscan MCP Server unlocks
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_balanceandget_balance_multi. - Transaction History — Fetch comprehensive lists of normal and internal transactions for any wallet address with
get_tx_listandget_tx_list_internal. - Token Tracking — Monitor transfers for ERC-20, ERC-721 (NFTs), and ERC-1155 tokens using specialized tools like
get_token_txandget_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.
How it works
1. Subscribe to this server
2. Enter your Etherscan API Key
3. Start auditing wallets and tracking transfers from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Web3 Developers — Debug smart contract interactions and verify transaction statuses directly from your IDE.
- Crypto Analysts — Track whale movements, token distributions, and wallet activity without manual block explorer searches.
- DeFi Users — Monitor your portfolio balances and transaction history through a simple chat interface.
Frequently asked questions about the Etherscan MCP Server
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.
