Why people use Etherscan

Etherscan for Real-Time Ethereum Blockchain Data

With this Connector, you just describe what you want to find. Ask your agent for the last five transactions for a specific wallet, and it pulls the data, filters it, and presents it to you in a clean format. You get the answers without the tab-switching.

What Vinkius changes

You get live blockchain data in your chat window instead of digging through a web explorer.

Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect

Questions about Etherscan.

The practical details behind the request, access and result.

Can the Etherscan MCP check balances on Polygon?

Yes, it supports multiple EVM chains including Polygon, BSC, and others by specifying the correct chain ID.

Does it support NFT transfers?

Yes, it can track both ERC-721 and ERC-1155 token transfers for specific wallet addresses.

How do I get my data?

You just need to provide your Etherscan API key in the setup. Once connected, you can ask for any data via your AI client.

Can it see internal transactions?

Yes, it has a specific capability to pull internal transactions that are often hidden from standard transaction lists.

Is it for any blockchain?

It is specifically for Ethereum and other EVM-compatible networks. It won't work for non-EVM chains like Bitcoin.

Can I check multiple wallets?

Yes, you can query the native balances for up to 20 different addresses in a single request.

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

You can use the get_balance_multi capability. 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 capability. 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.
