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_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
- Subscribe to this server
- Enter your Etherscan API Key
- 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.

Why AutoGen?
AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use Etherscan tools. Connect 19 tools through Vinkius and assign role-based access. a data analyst queries while a reviewer validates, with optional human-in-the-loop approval for sensitive operations.
- —
Multi-agent conversations: multiple AutoGen agents discuss, delegate, and collaboratively use Etherscan tools to solve complex tasks
- —
Role-based architecture lets you assign Etherscan tool access to specific agents. a data analyst queries while a reviewer validates
- —
Human-in-the-loop support: agents can pause for human approval before executing sensitive Etherscan tool calls
- —
Code execution sandbox: AutoGen agents can write and run code that processes Etherscan tool responses in an isolated environment
Etherscan in AutoGen
Etherscan and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Etherscan to AutoGen through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for Etherscan in AutoGen
The Etherscan MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 19 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in AutoGen only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
Etherscan for AutoGen
Every tool call from AutoGen to the Etherscan MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Etherscan tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
