MCP server for EVM crypto wallet operations using ethers.js v5
MCP server for EVM crypto wallet operations using ethers.js v5. The mcp cryptowallet evm mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 1 defined tool rather than through you.
This repository contains a Model Context Protocol (MCP) server that provides Claude with access to Ethereum and EVM-compatible blockchain operations via ethers.js v5. The server enables Claude to perform operations like creating wallets, checking balances, sending transactions, and interacting with smart contracts on EVM-compatible blockchains.
The server ships on npm as @mcp-dockmaster/mcp-cryptowallet-evm, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Everything the assistant can do here goes through one of these:
Building — The Building tool exposed by this serverYou will need one environment variable: PRIVATE_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP Cryptowallet Evm's toolset — Building — is a fair guide to whether it matches your workflow. It is maintained by dcSpark; worth a glance at recent repository activity before you build anything load-bearing on it.
