# Uniswap V3 Price MCP Server
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](https://infura.io/)).

```bash
git clone https://github.com/kukapay/uniswap-price-mcp.git
