Overview

MCP Ethers Wallet is a server implementation of the Model Context Protocol that allows AI tools to interact with Ethereum wallets and networks using Ethers.js v6.

To use MCP Ethers Wallet, install it via npm, start the server, and configure it with your Alchemy API key. You can then interact with the server through various tools provided.

  • Query blockchain data across multiple networks - Interact with smart contracts - Manage wallet operations - Resolve ENS names - Handle transactions and estimate gas costs
  1. Querying Ethereum blockchain data for analysis.
  2. Managing wallet operations for automated trading bots.
  3. Interacting with smart contracts for decentralized applications.

Add to your AI client

Use these steps to connect MCP Ethers Wallet in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "mcp-ethers-server-crazyrabbitltc": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-ethers-server-crazyrabbitltc"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "mcp-ethers-server-crazyrabbitltc": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-ethers-server-crazyrabbitltc"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "mcp-ethers-server-crazyrabbitltc": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-ethers-server-crazyrabbitltc"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "mcp-ethers-server-crazyrabbitltc": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-ethers-server-crazyrabbitltc"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "mcp-ethers-server-crazyrabbitltc": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-ethers-server-crazyrabbitltc"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
