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.

Why VS Code Copilot?
GitHub Copilot Agent mode brings Etherscan data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 19 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services
Etherscan in VS Code Copilot
Etherscan and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Etherscan to VS Code Copilot 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 VS Code Copilot
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 VS Code Copilot 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 VS Code Copilot
Every tool call from VS Code Copilot 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.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
