> Use this tool when you need to facilitate cross-chain interactions and token swaps across multiple blockchain networks. It solves problems of interoperability and fragmented liquidity by providing a unified interface for AI agents to query chains, obtain transaction quotes, and generate unsigned transactions. The Relay MCP Server takes in chain queries and transaction requests as inputs and outputs unsigned transaction data and quotes, making it ideal for use cases that require seamless cross-chain transactions and swaps.
