LI.FI MCP Server
A Model Context Protocol (MCP) server that provides comprehensive integration with the LI.FI API for cross-chain bridge and DEX aggregation services.
Overview
This MCP server enables AI assistants and applications to interact with LI.FI's cross-chain infrastructure through a standardized protocol. It provides access to blockchain network information, token data, bridging tools, transaction status tracking, and more.

Prerequisites
- Node.js (v16 or higher)
- npm or yarn
- LI.FI API key
Installation
- Clone the repository:
- Install dependencies:
- Obtain a LI.FI API key:
- Visit LI.FI Developer Portal to register and get your API key
- Keep your API key secure and ready for configuration
Configuration
The server requires the following configuration:
lifiApiKey
