探索x402支付API，检查运行时间和价格，并通过MCP检查每个中介的链上验证结算量。

什么是x402-list？

x402-list 是一个接受 x402（HTTP 402 稳定币）支付的服务目录。它监控列出的服务的正常运行时间、响应时间和状态，并衡量链上促进者的结算量。

该包是基于公开 x402-list HTTP JSON API 的薄包裹。它不持有密钥，不接触数据库，也不写入该目录。它通过模型上下文协议向 AI 代理开放该目录，作为七个工具：其中六个是免费且只读的，第七个 x402_assess_services 是唯一的付费工具，是一个传递，传递你在客户端签署的 x402 支付挑战（该包从不持有密钥，从不签名，也从不结算）。

安装与快速启动

通过可流式 HTTP 连接到托管服务器 https://mcp.x402-list.com/mcp，或通过 stdio 本地运行 npm 包。本地使用需要 Node.js 20 或更高版本和 npm;托管连接无需本地Node.js安装。

What is x402-list

x402-list is a directory of services that accept x402 (HTTP 402 stablecoin) payments. It monitors listed services for uptime, response time and status, and measures facilitator settlement volume on-chain.

This package is a thin wrapper over the public x402-list HTTP JSON API. It holds no keys, touches no database, and makes no writes to the directory. It exposes the directory to AI agents through the Model Context Protocol as seven tools: six are free and read-only, and the seventh, x402_assess_services, is the only paid one, a pass-through that relays an x402 payment challenge you sign yourself client-side (the package never holds keys, never signs, and never settles).

Install and quick start

Connect to the hosted server at https://mcp.x402-list.com/mcp using Streamable HTTP, or run the npm package locally over stdio. Local use requires Node.js 20 or newer and npm; the hosted connection needs no local Node.js installation.

Claude Code

Connect to the hosted server:

claude mcp add --transport http x402-list https://mcp.x402-list.com/mcp

Or use the local package instead:

claude mcp add --transport stdio x402-list -- npx -y x402-list-mcp

Choose one transport. See the Claude Code MCP documentation for configuration scopes.

Cursor

Add the hosted server to Cursor, then confirm the installation in Cursor.

The install link encodes the same configuration as this manual entry in .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "x402-list": {
      "url": "https://mcp.x402-list.com/mcp"
    }
  }
}

See the Cursor MCP documentation and install-link format.

VS Code

Add this entry to .vscode/mcp.json in your project, then start the server from the editor and use it in Copilot agent mode:

{
  "servers": {
    "x402-list": {
      "type": "http",
      "url": "https://mcp.x402-list.com/mcp"
    }
  }
}

See the VS Code MCP documentation for other configuration locations.

Codex

Add the hosted server with the Codex CLI:

codex mcp add x402-list --url https://mcp.x402-list.com/mcp

Or add this entry to ~/.codex/config.toml; the CLI and IDE extension share this configuration:

[mcp_servers.x402-list]
url = "https://mcp.x402-list.com/mcp"
