What is Bridge Rates Mcp

bridge-rates-mcp is an MCP server that provides real-time cross-chain bridge rates and optimal transfer routes to assist onchain AI agents in decision-making.

Use cases

Use cases include facilitating cross-chain asset transfers, optimizing transaction costs for users, and providing data for onchain AI agents to make informed decisions.

How to use

To use bridge-rates-mcp, clone the repository, install dependencies using npm, and configure your MCP client (like Claude Desktop) to connect to the server. Ensure to restart the client to access the tools.

Key features

Key features include retrieving cross-chain bridge rates for token pairs, listing supported blockchain networks, and obtaining a sorted list of bridges and exchanges for cross-chain transfers.

Where to use

bridge-rates-mcp can be used in decentralized finance (DeFi) applications, blockchain analytics, and any platform requiring real-time cross-chain transaction data.

Bridge Rates MCP Server

An MCP server that delivers real-time cross-chain bridge rates and optimal transfer routes to support decision-making by onchain AI agents.

Features

• Get Bridge Rates: Retrieve cross-chain bridge rates for token pairs, including USD values, gas costs, route providers and tags, presented in a Markdown table.
• List Supported Chains: Fetch a sorted list of blockchain networks supported by LI.FI.
• List Supported Bridges: Obtain a sorted list of bridges and exchanges available for cross-chain transfers.

Prerequisites

• Node.js: Version 18 or higher.
• npm: For dependency management.
• MCP Client: An MCP-compatible client (e.g., Claude Desktop) to interact with the server.

Installation

1. Clone the Repository:

   git clone https://github.com/kukapay/bridge-rates-mcp.git
   cd bridge-rates-mcp
   

2. Install Dependencies:

   npm install
   

3. Integrate with an MCP Client:
   Configure your MCP client (e.g., Claude Desktop) to connect to the server. For Claude Desktop, edit the configuration file (e.g., ~/Library/Application Support/Claude/claude_desktop_config.json on Mac or %APPDATA%\Claude\claude_desktop_config.json on Windows):

   {
     "mcpServers": {
       "bridge-rates": {
         "command": "node",
         "args": [
           "/absolute/path/to/bridge-rates-mcp/index.js"
         ]
       }
     }
   }
   

   Restart Claude Desktop and verify the tools are available (look for the hammer icon).

Tools

1. getBridgeRates

Fetches cross-chain bridge rates for a token pair between two chains, returning all available routes in a Markdown table.

Parameters:

• fromChainId (string, required): Source chain ID (e.g., “1” for Ethereum).
• toChainId (string, required): Destination chain ID (e.g., “10” for Optimism).
• fromTokenAddress (string, required): Source token contract address.
• toTokenAddress (string, required): Destination token contract address.
• fromAmount (string, optional): Amount to bridge in the smallest token unit (default: “10000000”).

Example Prompt:

What's the bridge rate from Arbitrum USDC to Optimism DAI?

Example Output:

| From Amount | From Amount USD | To Amount | To Amount USD | To Amount Min | Gas Cost USD | Providers | Tags                 |
|-------------|-----------------|-----------|---------------|---------------|--------------|-----------|----------------------|
| 10000000    | 10.00           | 9980000   | 9.98          | 9940000       | 0.2300       | hop       | RECOMMENDED,CHEAPEST |
| 10000000    | 10.00           | 9975000   | 9.97          | 9935000       | 0.2500       | connext   | None                 |

2. getSupportedChains

Fetches a sorted list of chains supported by LI.FI for cross-chain bridging, presented in a Markdown table.

Parameters: None.

Example Prompt:

List all supported chains for bridging.

Example Output:

| Chain Type | ID | Key | Name          | Native Token |
|------------|----|-----|---------------|--------------|
| EVM        | 1  | eth | Ethereum      | ETH          |
| EVM        | 10 | opt | Optimism      | ETH          |
| EVM        | 137| pol | Polygon       | MATIC        |
| SVM        | 101| sol | Solana        | SOL          |

3. getSupportedBridges

Fetches a sorted list of bridges and exchanges supported by LI.FI, presented in a Markdown table.

Parameters: None.

Example Prompt:
