Cross-DEX Prices & Spreads MCP Server

Cross-DEX Prices & Spreads is an MCP integration. Live cross-DEX pool prices, liquidity and spreads on 6 EVM chains, read from on-chain pool state.

Packages and local setup

The published npm package is arb-dex-mcp, version 1.0.1. Its declared MCP transport is stdio.

The package declares RAPIDAPI_KEY: Your own RapidAPI key for the Multi-Chain DEX Prices & Liquidity API (https://rapidapi.com/donnydev/api/multi-chain-dex-prices-liquidity). The free-tier subscription is enough to start. Required for live pool prices and fresh sweeps; without it get_chains, get_pairs and get_spreads fall back to a free hourly public snapshot and say so in the payload.; ARB_DEX_TIMEOUT_MS: Optional request timeout in milliseconds. Defaults to 45000 — a full-chain live scan is a real on-chain sweep and can take ~30s..
