Bridge Rates MCP server

Ask your AI for live cross-chain bridge rates and the cheapest route to move crypto between blockchains.

This is a small helper that lets your AI look up live rates for moving crypto tokens from one blockchain to another. It shows you the available routes, the fees, and which one is cheapest. It is handy if you move tokens between chains and want a quick comparison without opening five websites.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to an outside service. This one connects your AI to LI.FI, a service that gathers cross-chain bridge rates. Once it is set up, you can just ask your AI about a transfer and it will fetch the numbers for you.

What this MCP server does

You ask your AI something like what it costs to move USDC from Arbitrum to Optimism. Your AI passes the question to this helper. The helper asks LI.FI, which collects rates from many bridges and exchanges. Then it hands back a neat table of routes with amounts, fees, and provider names. Your AI shows you that table right in the chat.

Flow diagram: you ask your AI “What's the bridge rate from Arbitrum USDC to Optimism DAI?”, the Bridge Rates MCP server connects it to LI.FI, and you get back table of routes in chat.

What it gives back to you

Before you start

What you need

Node.js version 18 or newer installed on your computer
npm, which comes with Node.js
An MCP-compatible app such as the Claude desktop app
The bridge-rates-mcp files downloaded from GitHub

Good to know

The rates are live estimates and can change quickly, and the amounts are given in the smallest token unit, so double check the numbers before you actually send funds.
