Bridge Rates MCP Server: Real-Time Cross-Chain Intelligence for AI Agents

Stop manually comparing bridge rates across platforms. This MCP server transforms your AI agent into a cross-chain optimization engine, delivering real-time bridge rates and optimal routes directly within your development workflow.

Why You Need This

Building cross-chain applications means constantly juggling multiple bridge providers, comparing rates, and tracking gas costs. Instead of context-switching between different platforms or writing custom integrations for each bridge, you get unified access to LI.FI's comprehensive bridge data through a single MCP interface.

Your AI agent can now:

• Compare rates instantly across multiple bridges without leaving your development environment
• Identify optimal routes with gas cost analysis and provider recommendations
• Access real-time data for 20+ chains and dozens of bridge providers
• Make informed decisions with structured data that includes slippage, fees, and execution time

Key Benefits

Unified Bridge Intelligence: Query rates across Hop, Connext, Across, and other major bridges through one interface. No more switching between different documentation or APIs.

AI-Optimized Output: Returns structured markdown tables that your AI can immediately parse and reason about. Ask "What's the cheapest way to bridge USDC from Arbitrum to Optimism?" and get actionable comparisons.

Development Workflow Integration: Works seamlessly with Claude Desktop and other MCP-compatible tools. Your bridge research happens in the same environment where you're building.

Real-Time Accuracy: Pulls live data from LI.FI's aggregation layer, ensuring your decisions are based on current market conditions, not stale cached data.

Real-World Use Cases

DeFi Protocol Development: You're building a yield farming strategy that needs to move assets across chains. Instead of hardcoding bridge selections, your AI agent can evaluate current rates and recommend the most cost-effective path for each transaction.

Cross-Chain Arbitrage: Your trading bot needs to identify profitable opportunities across different chains. The MCP server provides the bridge cost data needed to calculate whether arbitrage opportunities are actually profitable after fees.

Portfolio Management Tools: Building a multi-chain portfolio dashboard? Your AI can recommend optimal rebalancing routes, taking into account both bridge fees and execution time.

Smart Contract Integration: When your contracts need to suggest bridge routes to users, you can query real-time rates to provide the most current recommendations rather than static lists.

Integration in Your Stack

The MCP server plugs directly into your existing AI development workflow:

1. Install and Configure: Clone the repo, install dependencies, and add your configuration to Claude Desktop or your MCP-compatible client
2. Query Bridge Data: Use natural language to ask for bridge comparisons, supported chains, or optimal routes
3. Get Structured Responses: Receive markdown tables with all the data your AI needs to make routing decisions
4. Implement Recommendations: Use the returned data to execute bridge transactions or provide user recommendations

The server handles the complexity of interfacing with multiple bridge providers while giving you clean, structured data that's immediately actionable.

Getting Started

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

Add to your Claude Desktop configuration:

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

Then ask your AI: "What's the best bridge rate from Ethereum USDC to Polygon USDC for a $10,000 transfer?"

You'll get a comprehensive comparison showing rates, fees, gas costs, and provider recommendations in a format that's immediately actionable for your cross-chain development decisions.

Transform your cross-chain development from guesswork to data-driven optimization. Your AI agent becomes your bridge intelligence layer, delivering the insights you need exactly when you need them.
