EVM MCP Server

A comprehensive Model Context Protocol (MCP) server that provides blockchain services across 60+ EVM-compatible networks including Ethereum, Optimism, Arbitrum, Base, Polygon, and many others. This server enables AI agents to interact with blockchain networks through a unified interface.

Features

Blockchain Data Access

• Multi-chain support for 60+ EVM-compatible networks (34 mainnets + 26 testnets)
• Chain information including blockNumber, chainId, and RPCs
• Block data access by number, hash, or latest
• Transaction details and receipts with decoded logs
• Address balances for native tokens and all token standards
• ENS resolution for human-readable Ethereum addresses (use 'vitalik.eth' instead of hex addresses)

Token Services

• ERC20 Tokens: Get metadata, check balances, transfer tokens, approve spending allowances
• NFTs (ERC721): Get collection and token metadata, verify ownership, transfer NFTs, retrieve token URIs
• Multi-tokens (ERC1155): Get token balances and metadata, transfer tokens with quantity

Smart Contract Interactions

• Read contract state through view/pure functions
• Execute state-changing functions with automatic ABI fetching
• Contract verification to distinguish from EOAs
• Event logs retrieval and filtering
• Automatic ABI fetching from Etherscan v2 API across all networks (no need to know ABIs in advance)
• Multicall support for batching multiple reads in a single RPC call

Transaction Support

• Flexible wallet support with Private Key or Mnemonic (BIP-39) with HD path support
• Native token transfers across all supported networks
• Gas estimation for transaction planning
• Transaction status and receipt information
• Error handling with descriptive messages

Message Signing

• Personal message signing for authentication and verification
• EIP-712 typed data signing for gasless transactions and meta-transactions
• SIWE (Sign-In With Ethereum) support
• Permit signatures for gasless token operations
• Meta-transaction support for relay services

AI-Guided Workflows

Includes 10 AI-friendly prompts that guide agents through complex workflows:

• Transaction preparation and execution
• Wallet analysis and holdings review
• Smart contract exploration with ABI fetching
• Contract interaction guidance
• Network information and comparisons
• Approval auditing and management
• Error diagnosis and troubleshooting

Usage Notes

• All tools that accept Ethereum addresses also support ENS names (e.g., 'vitalik.eth')
• Automatic ABI fetching eliminates the need to know contract ABIs in advance
• Use stdio mode for CLI tools or HTTP mode with SSE for web applications
• Configure wallet using either EVM_PRIVATE_KEY or EVM_MNEMONIC for write operations
• Optional ETHERSCAN_API_KEY enables ABI fetching from block explorers
