kukapay/uniswap-price-mcp

An MCP server that delivers real-time token prices from Uniswap V3 across multiple chains — optimized for AI agents and DeFi automation.

Features

• Supported Chains: Ethereum Mainnet (1), Polygon (137), Arbitrum (42161), Optimism (10).
• Token Price Fetching: Queries Uniswap V3 pools for token prices against USDT, USDC, or WETH (in that order) with automatic decimal and symbol retrieval.
• USD Conversion: Optional USD price conversion using CryptoCompare API for all quote tokens.

Prerequisites

• Node.js (v18 or higher recommended) and npm.
• Infura Account: Obtain an INFURA_PROJECT_ID with access to Ethereum, Polygon, Arbitrum, and Optimism (sign up at Infura).
