Uniswap V3 Price Server

Example Use Cases

• 1

  Real-time token price lookups across Ethereum, Polygon, Arbitrum, and Optimism via Uniswap V3 pools.

• 2

  Automatic token metadata handling (symbols and decimals) and prioritized quote routing (USDT → USDC → WETH).

• 3

  Optional USD conversion of quote tokens using CryptoCompare for fiat-denominated decision making.

Description

This project queries Uniswap V3 pools to deliver token prices against common quote tokens (USDT, USDC, WETH) with automatic decimal and symbol handling. It supports Ethereum Mainnet, Polygon, Arbitrum, and Optimism and can optionally convert quote token prices to USD via the CryptoCompare API. The server is designed to be run as an MCP service (Node.js) and is optimized for integration with AI agents and automated DeFi workflows. It requires an Infura project ID to access RPC endpoints for the supported chains.
