EVM MCP Server

EVM MCP Server

The EVM MCP Server is a fully‑featured Model Context Protocol (MCP) backend that unlocks blockchain functionality for AI assistants. By exposing a unified set of tools and resources, it lets agents query state, read contracts, transfer tokens, and perform smart‑contract interactions across more than thirty EVM‑compatible networks—including Ethereum mainnet, Optimism, Arbitrum, Base, Polygon, zkSync Era, and many others. This breadth of coverage removes the need for separate RPC endpoints or custom adapters; a single MCP call can reach any supported chain, dramatically simplifying AI‑driven blockchain workflows.

What makes this server especially valuable is its consistent interface. Every tool accepts the same argument shapes, and address parameters automatically resolve ENS names (e.g., ) to raw addresses. This feature reduces friction for developers and users alike, allowing natural language instructions such as “transfer 10 USDC to vitalik.eth” to be translated into precise blockchain calls. The server also bundles common token operations—ERC20 transfers, ERC721 ownership checks, ERC1155 batch moves—and provides rich metadata queries (token name, symbol, decimals, supply) and balance checks for native coins. By offering both read‑only and signed write services (via private key signing), the MCP server covers the full spectrum of on‑chain interactions that an AI assistant might need.

Key capabilities include:

• Multi‑chain data access: read blocks, transactions, receipts, and chain info (block number, chain ID) for any supported network.
• Token services: ERC20 balances and transfers, ERC721 ownership verification and transfer, ERC1155 batch handling.
• Smart contract interaction: view/pure calls, transaction signing, event log filtering, and contract verification to distinguish EOAs from contracts.
• Transaction utilities: gas estimation, native token transfers, status checks, and detailed error reporting.
• ENS resolution: all address inputs support human‑readable names, automatically mapped to addresses behind the scenes.

In practice, this MCP server enables a variety of real‑world scenarios. A financial AI could automatically fetch portfolio balances across chains, reconcile token holdings, and execute trades on behalf of users. A game bot might read NFT ownership data from Polygon or zkSync and trigger in‑game rewards. A compliance tool could audit transaction histories across multiple networks for regulatory reporting, all without custom RPC handling or chain‑specific SDKs. Developers can embed the server into existing AI workflows, allowing agents to discover and invoke blockchain services as first‑class tools in their reasoning pipelines.

Because the server is written in TypeScript and leverages the Viem library, it benefits from strong type safety and up‑to‑date EVM tooling. The design emphasizes simplicity, extensibility, and security: each tool is self‑contained, can be extended with new networks or token standards, and uses secure signing practices for write operations. This combination of a rich feature set, cross‑chain reach, and developer‑friendly interface makes the EVM MCP Server a standout solution for anyone looking to integrate blockchain capabilities into AI assistants.
