What is the Relay Protocol MCP server?

Most monitoring and observability work still happens through a UI a human drives. Relay Protocol MCP server moves it into the conversation instead. Model Context Protocol server for Relay Protocol REST API.

The short version

Model Context Protocol (MCP) server for the Relay Protocol REST API enabling cross-chain bridging and token swapping operations.

  • Cross-Chain Bridging — - Bridge tokens between 50+ blockchain networks
  • Multi-Chain Swaps — - Aggregate tokens from multiple chains into single destination
  • Real-Time Pricing — - Get current token prices across all supported chains
  • Request Monitoring — - Track execution status and transaction details
  • Currency Discovery — - Browse 1000+ supported tokens with filtering
  • Zero Configuration — - No API keys required (free public API)

The tools it exposes

The server publishes 10 tools. What each one is for:

  • Production — Ready** infrastructure handling millions in daily volume
  • relay_get_chains — List supported blockchain networks
  • relay_get_token_price — Get real-time token prices
  • relay_get_currencies — Discover tokens with advanced filtering
  • relay_get_quote — Generate bridging/swap quotes
  • relay_swap_multi_input — Execute multi-chain swaps
  • relay_get_execution_status — Track request progress
  • relay_get_requests — Monitor request history
  • relay_transactions_index — Index transactions for tracking
  • relay_transactions_single — Index specific transfers/wraps

What it needs from you

  • Node.js >= 20.0.0 - pnpm package manager

Getting it running

The server ships on npm as @railway/cli, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

How it compares

This sits in the monitoring and observability group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Relay Protocol's toolset — Production, relay_get_chains, relay_get_token_price and 7 more — is a fair guide to whether it matches your workflow. It is maintained by warengonzaga; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 10 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Relay Protocol.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Relay Protocol to MCP-compatible AI assistants such as Claude and Cursor, exposing 10 tools (Production, relay_get_chains, relay_get_token_price, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Relay Protocol directly.
