Overview

AI-generated overview

Relay MCP lets an assistant fetch cross-chain bridge and swap quotes, estimate fees, and track transactions through the Relay Protocol API.

What you can do
  • Get cross-chain bridge and swap quotes.
  • Estimate fees for a transfer or swap.
  • Track the status of Relay transactions.
  • The server exposes no tool list in the supplied data, so exact tool names and parameters are not documented here.
When to use it
Useful when you want an assistant to look up bridging or swapping routes and costs across chains, or to check on a Relay transaction, without leaving the chat.
Requirements
Runs locally as an npm package over stdio on a desktop client. Network access to the Relay API is required; the base URL defaults to the public endpoint and can be overridden with RELAY_API_URL. An optional RELAY_API_KEY raises rate limits.
Before you install
The server handles crypto bridging and swapping, so quotes and fee estimates may lead to real on-chain transactions with financial risk; verify amounts and destinations before acting. The optional RELAY_API_KEY is a secret and should be supplied through the environment, not shared. Requests go to the third-party Relay API.

Installation

In SourceWeft

  1. Open Relay in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
