Features

This MCP server provides 6 powerful tools for querying and analyzing DeFi lending data:

1. get_latest_rates

Get the latest lending rates for collateralized borrowing markets.

Parameters:

• platform (optional): Filter by platform (Aave, Morpho, Compound, Venus, Lista, HyperLend, Fluid, HypurrFi, Euler, Drift, Jupiter)

• chain (optional): Filter by blockchain (ethereum, arbitrum, base, bsc, solana, hyperevm)

• asset (optional): Filter by borrow asset (USDC, USDT, WETH, etc.)

• collateral (optional): Filter by collateral asset

• limit (optional): Maximum results to return (default: 10)

• sort (optional): Sort results by rate — borrow_lowest, borrow_highest, supply_highest, or supply_lowest

2. get_earn_markets

Get single-asset earn/vault products (no collateral required). Perfect for finding the best passive yield opportunities.

Parameters:

• platform (optional): Filter by platform (Morpho, Spark, Compound, AAVE, Lista, Felix, Euler)

• chain (optional): Filter by blockchain (ethereum, arbitrum, base, bsc, solana)

• asset (optional): Filter by deposit asset (USDC, USDT, stUSDS, sUSDS, WETH, SOL)

• limit (optional): Maximum results to return (default: 10)

• sort (optional): Sort by APY — supply_highest or supply_lowest

Examples:

• Find best stablecoin yields: asset: "USDC", sort: "supply_highest"

• Check Spark stUSDS APY: platform: "Spark", asset: "stUSDS"

• Best Morpho Vaults: platform: "Morpho", sort: "supply_highest"

3. get_dbi_index

Get the DBI (DeFi Borrow Index) - a weighted average of stablecoin borrow rates across major protocols.

No parameters required.

4. search_best_rates

Find the best borrow or supply rates for a specific asset.

Parameters:

• asset (required): The asset to search for

• type (required): 'borrow' or 'supply'

• chain (optional): Filter by blockchain

• limit (optional): Number of results (default: 10)

5. calculate_looping_strategy

Calculate leverage looping strategy metrics.

Parameters:

• platform (required): The lending platform

• asset (required): The asset to borrow

• collateral (required): The collateral asset

• collateralAmount (required): Amount of collateral tokens

• collateralPrice (required): Current price in USD

• ltv (required): Target LTV ratio percentage (e.g., 75)

6. compare_platforms

Compare rates across different platforms for the same asset pair.

Parameters:

• asset (required): The borrow asset

• collateral (required): The collateral asset

• chain (optional): Filter by blockchain

🚀 Quick Start

1. Install the package:

2. Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

3. Restart Claude Desktop and start asking:

   • "What are the current USDC borrow rates on Aave?"

   • "Find the best USDT supply rates across all platforms"

   • "Calculate a looping strategy with 10 ETH on Morpho"

Installation

Option 1: Install from npm (Recommended)

Option 2: Install from source

Configuration

For Claude Desktop

Add to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

If installed from npm:

If installed from source:

For Other MCP Clients

Use the stdio transport protocol:

Usage Examples

Once configured, you can ask Claude:

Query Lending Rates

"What are the current USDC borrow rates on Aave?"

"Show me all Ethereum lending rates for WETH collateral"

"Find the cheapest place to borrow USDC right now"

Query Earn Markets

"What's the APY for Spark stUSDS?"

"Find the best USDC earn vaults across all platforms"

"Show me Morpho vault yields on Ethereum"

"What are the top 5 highest yield single-asset deposit products?"

Search Best Rates

"Find the best USDT supply rates across all platforms"

"What's the cheapest place to borrow USDC?"

Calculate Looping Strategy

"Calculate a looping strategy on Aave using 10 ETH as collateral (ETH price $3000) at 75% LTV to borrow USDC"

Compare Platforms

"Compare USDC/WETH borrow rates across all platforms"

Get DBI Index

"What's the current DBI stablecoin borrow cost index?"
