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 assetlimit(optional): Maximum results to return (default: 10)sort(optional): Sort results by rate —borrow_lowest,borrow_highest,supply_highest, orsupply_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_highestorsupply_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 fortype(required): 'borrow' or 'supply'chain(optional): Filter by blockchainlimit(optional): Number of results (default: 10)
5. calculate_looping_strategy
Calculate leverage looping strategy metrics.
Parameters:
platform(required): The lending platformasset(required): The asset to borrowcollateral(required): The collateral assetcollateralAmount(required): Amount of collateral tokenscollateralPrice(required): Current price in USDltv(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 assetcollateral(required): The collateral assetchain(optional): Filter by blockchain
🚀 Quick Start
- Install the package:
npm install -g @asahi001/defi-rates-mcp
- Add to your Claude Desktop config (
~/Library/Application Support/Claude/claude_desktop_config.json):
{
"mcpServers": {
"defi-rates": {
"command": "npx",
"args": ["-y", "@asahi001/defi-rates-mcp"]
}
}
}
- 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)
npm install -g @asahi001/defi-rates-mcp
Option 2: Install from source
git clone https://github.com/qingfeng/defi-rates-mcp.git

npm install
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:
{
"mcpServers": {
"defi-rates": {
"command": "npx",
"args": ["-y", "@asahi001/defi-rates-mcp"]
}
}
}
If installed from source:
{
"mcpServers": {
"defi-rates": {
"command": "node",
"args": ["/path/to/defi-rates-mcp/index.js"]
}
}
}
For Other MCP Clients
Use the stdio transport protocol:
node /Users/qingfeng/Desktop/solana_lp/defi-rates-mcp/index.js
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?"
