mcp-etherscan-server
Verified Safeby dennisonbertram
Overview
Provides a multi-chain Etherscan-based interface for fetching Ethereum blockchain data, including balances, transactions, token transfers, contract details, and network statistics across 70+ networks.
Installation
npm startEnvironment Variables
- ETHERSCAN_API_KEY
Security Notes
The server correctly handles sensitive API keys via environment variables (ETHERSCAN_API_KEY is explicitly required and checked). It uses reputable external APIs (Etherscan, eth.llamarpc.com for ENS) and robust URL building with parameter encoding. No 'eval' or obvious malicious code patterns were found. Dependency usage is for standard utilities and cryptographic operations. The `parseApiResponse` function includes basic structural and status validation, reducing the risk of malformed API responses causing unexpected behavior.
