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.

Frequently asked questions

1

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.

2

What dependencies are required to run the server?

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

3

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.

4

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.

5

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.
