EVM MCP Server
An MCP server that provides AI agents with read and write access to 60+ EVM-compatible blockchain networks. Supports querying balances, transactions, blocks, and smart contract state, plus write operations like token transfers and contract interactions. Features automatic ABI fetching from block explorers and ENS name resolution.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
EVM/Ethereum blockchain MCP. RPC node access — use authenticated endpoints. NEVER expose private keys to agent. Use read-only RPC for data queries. Signing operations need hardware wallet.
⚡ Reliability
Best When
You want an AI agent to query or interact with Ethereum and EVM-compatible chains, and you understand the security implications of providing wallet credentials.
Avoid When
You need to manage significant funds (private key exposure risk), work with non-EVM chains, or require sub-second transaction execution.
Use Cases
- • AI-assisted blockchain data queries across 60+ EVM networks
- • Automating ERC20/ERC721/ERC1155 token transfers via AI agents
- • Smart contract interaction and state inspection through natural language
- • Cross-chain portfolio monitoring and transaction analysis
Not For
- • Non-EVM blockchains (Solana, Bitcoin, Cosmos, etc.)
- • High-frequency trading or latency-sensitive operations
- • Users uncomfortable with exposing private keys to an MCP server
- • Production custodial wallet management (private key in env var is risky)
Interface
Authentication
Optional EVM_PRIVATE_KEY or EVM_MNEMONIC env var for write operations. ETHERSCAN_API_KEY for automatic ABI fetching. Read-only operations require no auth. Significant security concern: private keys passed as environment variables.
Pricing
MIT licensed. Uses public RPC endpoints by default. Blockchain transactions incur gas fees. Etherscan API key is free tier available.
Agent Metadata
Known Gotchas
- ⚠ Private keys stored in environment variables - high risk if server is compromised
- ⚠ Write operations are not idempotent - retrying a failed transfer could double-spend
- ⚠ No transaction approval/confirmation flow - agent can send funds without human review
- ⚠ Gas estimation may be inaccurate during network congestion
- ⚠ Public RPC endpoints may rate-limit under heavy use
