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").
