Uniswap V3 Price MCP Server

Overview

The Uniswap V3 Price MCP Server is a lightweight, real‑time price oracle that bridges AI assistants with the Uniswap V3 liquidity pools on multiple Ethereum‑compatible chains. By exposing token prices directly through the MCP interface, it removes the need for AI agents to implement their own blockchain queries or maintain expensive node infrastructure. Instead, developers can simply ask the AI for a token’s current value and receive an accurate response backed by on‑chain data.

At its core, the server listens for two primary tools: and . The former returns a concise table of all networks the server can query, ensuring agents know exactly which chains are available. The latter performs a multi‑step lookup: it first searches for the token’s pool against USDT, then USDC, and finally WETH. This fallback strategy guarantees a price is found for most ERC‑20 tokens without manual configuration, and the server automatically handles token decimals and symbol resolution. For users who require fiat context, an optional USD conversion is provided via the CryptoCompare API, turning raw pool data into dollar values that AI assistants can present directly to end users.

Developers benefit from the server’s chain‑agnostic design. Whether a project operates on Ethereum Mainnet, Polygon, Arbitrum, or Optimism, the same MCP endpoint delivers consistent pricing data. This uniformity simplifies AI workflows: a single prompt can fetch prices across networks without switching contexts or writing custom code for each chain. In addition, the server’s Node.js implementation and minimal dependencies make it easy to deploy on existing infrastructure—whether in a cloud function, Docker container, or as part of an automated DeFi bot.

Real‑world scenarios that leverage this MCP include:

• Portfolio dashboards where an AI assistant can report the current value of a user’s holdings across multiple chains.
• DeFi strategy bots that need live price feeds to trigger arbitrage or liquidity provision actions.
• Chatbot interfaces for exchanges and wallets that answer “What’s the price of LINK on Polygon?” in real time.
• Analytics pipelines that aggregate token prices for reporting or risk management, all orchestrated by an AI workflow.

What sets this MCP apart is its simplicity coupled with robustness. By abstracting the complexities of Uniswap V3 pool queries, decimal handling, and cross‑chain connectivity behind a single MCP interface, it empowers AI assistants to provide instant, accurate price information without exposing developers to the intricacies of blockchain data fetching. This makes it an essential component for any AI‑driven DeFi application that requires reliable, up‑to‑date market data.
