Cross-DEX Prices & Spreads

Overview

Cross-DEX Prices & Spreads is an MCP server that surfaces live pool prices, liquidity data, and spreads across decentralized exchanges on 6 EVM chains. It reads directly from on-chain pool state, letting AI assistants query real-time DEX metrics as native tools instead of requiring manual lookups or context switching.

The server runs locally via the npm package arb-dex-mcp, installed with npx -y arb-dex-mcp. It requires an API key for authentication. Version v1.0.1 is available now under the MIT license, with full source code at donnywin85/arb-dex-mcp on GitHub.

Cross-DEX Prices & Spreads belongs in the Finance category on mcp.site and works with any MCP client, including Claude Desktop, Claude Code, Cursor, VS Code, and others. If you maintain this server, claim this listing to verify ownership and keep information up to date.
