Relay

Relay Protocol's MCP server gives you programmatic access to cross-chain bridging and swaps across multiple networks. You get quote generation for token transfers between chains, fee estimation to understand costs before executing, and transaction tracking to monitor bridge operations in flight. Reach for this when you're building workflows that need to move assets across different blockchains without manually juggling multiple bridge interfaces. It abstracts the complexity of cross-chain operations into a set of callable tools, so you can price routes, compare fees, and execute transfers through a single integration point rather than wiring up individual bridge APIs.
