Overview

What is @sinco-lab/evm-mcp-server?

An EVM interaction service gateway based on Model Context Protocol (MCP) and Viem, enabling AI agents or services to securely interact with a configured EVM-compatible blockchain.

How to use @sinco-lab/evm-mcp-server?

Install dependencies with pnpm install, build with pnpm run build, then configure environment variables (WALLET_PRIVATE_KEY, RPC_PROVIDER_URL) in a .env file or directly in a client’s MCP server config. Run the server using node build/evm.js or configure clients like Cursor or Claude Desktop to launch it automatically.

FAQ from @sinco-lab/evm-mcp-server

What is the purpose of @sinco-lab/evm-mcp-server?

It acts as a gateway for AI agents or MCP clients to securely interact with EVM-compatible blockchains, exposing blockchain operations as standardized MCP tools.

What dependencies are required to run the server?

Node.js version 18.0.0 or higher and the pnpm package manager are required.

How are blockchain credentials configured?

The server uses environment variables WALLET_PRIVATE_KEY (the wallet’s private key) and RPC_PROVIDER_URL (the JSON‑RPC endpoint). These can be placed in a .env file or directly in the MCP client’s configuration file.

Which EVM operations does the server support?

The server exposes tools for checking balances, sending native tokens, transferring ERC20 tokens, signing messages, getting token allowances, approving/revoking allowances, and more – a full list is available in the README.

How should private keys be managed for security?

It is strongly recommended to use a dedicated wallet for testing. Never commit private keys to version control, and avoid placing them directly in configuration files (e.g., .cursor/mcp.json) for high‑value environments.
