Getting Started

Installation

Using the Install Script

You can install the LI.FI MCP server using the following command:

curl https://raw.githubusercontent.com/lifinance/lifi-mcp/refs/heads/main/install.sh | bash

Using Go Install

Alternatively, you can install using Go:

go install github.com/lifinance/lifi-mcp@latest

Wallet Management

Using an Existing Keystore

Run the server with an Ethereum keystore file:

lifi-mcp server --keystore <keystore-name> --password <keystore-password>

The server will search for a file containing this name in the standard Ethereum keystore directory:

• Linux: ~/.ethereum/keystore
• macOS: ~/Library/Ethereum/keystore
• Windows: %APPDATA%\Ethereum\keystore

Creating a New Wallet

Create a new wallet keystore:

lifi-mcp new-wallet --name <wallet-name> --password <wallet-password>

This generates a new Ethereum wallet, saves it to the standard keystore location, and displays the wallet address.

Usage with Desktop App

To integrate this server with the desktop app, add the following to your app's server configuration:

{
  "mcpServers": {
    "lifi": {
      "command": "lifi-mcp",
      "args": ["server"]
    }
  }
}

For wallet functionality, include keystore parameters:

{
  "mcpServers": {
    "lifi": {
      "command": "lifi-mcp",
      "args": ["server", "--keystore", "your-keystore", "--password", "your-password"]
    }
  }
}
