About Cross-DEX Prices & Spreads
Cross-DEX Prices & Spreads is an MCP server published by the GitHub account donnywin85. Live cross-DEX pool prices, liquidity and spreads on 6 EVM chains, read from on-chain pool state.
It runs on your own machine: your AI client starts it from the npm package arb-dex-mcp at version 1.0.1.
It asks for one secret: RAPIDAPI_KEY. Give it a key with the least access that still works.
Version 1.0.1 was published on 15 August 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
RAPIDAPI_KEY | No | Yes | 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 | No | No | Optional request timeout in milliseconds. Defaults to 45000 — a full-chain live scan is a real on-chain sweep and can take ~30s. |
