defi-mcp

An open-source MCP server providing AI agents with direct, on-chain access to DeFi data on EVM chains like Polygon and Arbitrum. It retrieves wallet balances, Aave v3 lending positions, and live token prices via Chainlink oracles without relying on centralized APIs. It also simulates Uniswap v3 swaps to estimate output amounts and fees.
