MetaMask

A MetaMask MCP server that enables AI assistants to interact with Ethereum blockchain networks through MetaMask wallet integration, built using TypeScript with wagmi and viem libraries. The implementation provides comprehensive blockchain functionality including wallet connection via QR codes, transaction sending, smart contract deployment and interaction, ENS resolution, gas estimation, and chain switching, while keeping private keys secure within the user's MetaMask wallet rather than exposing them to the AI agent. Designed for developers and users who want to perform blockchain operations through conversational interfaces, it supports workflows like DeFi interactions, NFT management, contract testing, and general Web3 development tasks across multiple Ethereum networks including mainnet and testnets.
