Etherscan Mcp Server
Connect agents to Etherscan’s Ethereum explorer API for balances, transactions, and contract context while building Web3 apps.
Overview
Etherscan MCP Server is a Build-phase MCP server that exposes the Etherscan Ethereum blockchain explorer API to AI coding assistants.
What is this MCP server?
- MCP wrapper for the Etherscan Ethereum blockchain explorer API
- npm package etherscan-mcp-server v1.0.0 with stdio transport
- Supports agent workflows for transactions, accounts, and contract inspection on Ethereum
- Pairs naturally with DeFi or market data MCP servers for fuller Web3 stacks
- Repository friendlygeorge/etherscan-mcp-server on GitHub
- Published version 1.0.0 as npm package etherscan-mcp-server
- stdio MCP transport per schema 2025-12-11
- Targets Etherscan Ethereum blockchain explorer API
What problem does it solve?
Web3 solo builders lose flow switching between Etherscan and the IDE when agents could fetch chain data programmatically.
Who is it for?
Indie Ethereum developers who want explorer lookups, transaction context, and contract checks inside their agent workflow.
Skip if: Builders targeting chains Etherscan does not cover, or teams that forbid third-party explorer API dependencies.
What do I get? / Deliverables
With the MCP server configured, agents can pull Ethereum explorer results as you implement and debug on-chain features.
- Agent-driven Ethereum transaction and account queries
- Faster contract debugging sessions with inline explorer data
- Reduced context switching between IDE and Etherscan UI

How it compares
Ethereum on-chain explorer MCP, not DeFi TVL aggregates or CEX price tickers.
