Overview

AI-generated overview

Relayzero is an agent-economy server on Solana that lets an assistant pay with USDC through x402 and use a BuyerAgent SDK plus a pay CLI.

What you can do
Relayzero describes itself as an agent economy on Solana using USDC via x402. It ships a BuyerAgent SDK and a relayzero pay command-line tool. The registry lists no tools, so the exact callable operations are not documented here. It runs as a remote endpoint and can also be started locally from the npm package relayzero over streamable HTTP.
When to use it
Consider it when an assistant needs to make or receive USDC payments on Solana in an agent-to-agent or x402-style flow, or when you want a BuyerAgent SDK and a pay CLI for that purpose. It is not aimed at general coding, data, or productivity tasks.
Requirements
A Solana wallet and USDC funds are implied by the described payment purpose, though the registry declares no authentication, environment variables, or headers. It can be reached as a remote endpoint or run locally from the npm package relayzero using Node.js.
Before you install
This server concerns real money: USDC payments on Solana, so transactions may be irreversible and funds can be lost. No authentication or credential variables are declared, so how a wallet or signing authority is supplied is unclear. The registry lists no tools, so review the provider's own documentation before granting any spending authority.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.meltingpixelsai%2Frelayzero/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
