evm-mcp-server

A comprehensive Model Context Protocol (MCP) server for blockchain services across 30+ EVM-compatible networks. Enables AI agents and applications to interact with Ethereum, Optimism, Arbitrum, Polygon, Base, and many more chains through a unified interface.

Features

Blockchain Data Access

• Multi-chain support for 30+ EVM-compatible networks (Ethereum, Optimism, Arbitrum, Polygon, Base, Avalanche, BSC, etc.)
• Chain information retrieval (blockNumber, chainId, RPC URLs)
• Access block data by number, hash, or latest
• Retrieve transaction details and receipts with decoded logs
• Address balance queries for native tokens and all supported token standards
• ENS resolution for human-readable Ethereum addresses (e.g., 'vitalik.eth')

Token Services

• ERC20:
  • Get token metadata (name, symbol, decimals, supply)
  • Check token balances
  • Transfer tokens
  • Approve spending allowances
• NFTs (ERC721):
  • Get collection and token metadata
  • Verify token ownership
  • Transfer NFTs
  • Retrieve token URIs and count holdings
• ERC1155 (Multi-tokens):
  • Get token balances and metadata
  • Transfer tokens with quantity
  • Access token URIs

Smart Contract Interactions

• Read contract state (view/pure functions)
• Write to contracts with private key signing
• Contract verification (distinguish contract from EOA)
• Retrieve and filter event logs

Transactions

• Native token transfers across all supported networks
• Gas estimation for transactions
• Transaction status and receipt information
• Error handling with descriptive messages

ENS Support

• ENS name resolution for all address parameters in tools/resources

API and Tools

• Exposes MCP tools for ERC20/NFT/ERC1155/token operations, contract reads/writes, ENS resolution, etc.
• Resource URIs for chain, block, address, transaction, token, NFT, and ERC1155 data
• Supports both CLI (stdio) and HTTP/SSE server modes
• Integration with Cursor and Claude CLI

Security Considerations

• Private keys are only used for transaction signing (never stored)
• Recommendations for HTTPS, authentication, and rate limiting in production

Developer Experience

• Easily extensible (add new services/tools/resources/networks)
• Hardcoded config (chain, server port/host) can be modified in source

Supported Networks (selection)

• Mainnets: Ethereum, Optimism, Arbitrum, Base, Polygon, Avalanche, BSC, zkSync, Linea, Celo, Gnosis, Fantom, Filecoin, Moonbeam, Cronos, Scroll, Mantle, Blast, and more
• Testnets: Sepolia, Goerli, Holesky, Fuji, Amoy, and others

Installation & Usage

• Requires Bun 1.0.0+ or Node.js 18.0.0+
• Install dependencies with bun install or npm install
• Run server via bun start, bun start:http, or with npx @mcpdotdirect/evm-mcp-server
• Integrate with Cursor via .cursor/mcp.json or with Claude CLI
