Compatible with every major AI agent and IDE
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.

Etherscan in Google ADK
Etherscan and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Etherscan to Google ADK 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 Google ADK
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 Google ADK 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.

* Every 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 optimized for native MCP execution. See our infrastructure
How Vinkius secures
Etherscan for Google ADK
Every tool call from Google ADK 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 Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
