DEPRECATED: no live endpoint (api.x402.org does not resolve)
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
X402_API_KEY标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"x402": {
"command": "npx",
"args": [
"-y",
"@codespar/mcp-x402"
],
"env": {
"X402_API_KEY": "your-value"
}
}
}
}在终端中运行这条命令
claude mcp add x402 --env X402_API_KEY=your-value -- npx -y @codespar/mcp-x402运行前请先填写空着的值。

Deprecated: no live endpoint. Measured on 2026-09-27 against two public DNS resolvers (8.8.8.8 and 1.1.1.1):
api.x402.org, the only host this server calls, does not resolve in DNS. x402 has no central API: it is an HTTP 402 protocol, and each seller picks the facilitator that verifies payment. No tool in this server reaches a service. The package is deprecated on npm and stays in this repository for reference only. If you have a working endpoint, point the server at it withX402_BASE_URL. To bring the package back, open an issue in mcp-dev-latam with the provider's documented base URL.
MCP server for x402 — HTTP-native micropayments protocol by Coinbase (USDC on Base/Solana)
x402 is an open protocol that enables machine-to-machine micropayments at the HTTP layer. When an AI agent requests a resource and receives HTTP 402 Payment Required, it automatically sends a USDC payment on-chain and retries — no checkout UI, no merchant integration, pure HTTP.
This is the payment rail purpose-built for agentic commerce.
Add to ~/.config/claude/claude_desktop_config.json:
{
"mcpServers": { "x402": { "command": "npx", "args": ["-y", "@codespar/mcp-x402"], "env": { "X402_API_KEY": "your-key", "X402_WALLET_ADDRESS": "your-wallet-address" } } } }
claude mcp add x402 -- npx @codespar/mcp-x402
Add to .cursor/mcp.json or .vscode/mcp.json:
{
"servers": { "x402": { "command": "npx", "args": ["-y", "@codespar/mcp-x402"], "env": { "X402_API_KEY": "your-key", "X402_WALLET_ADDRESS": "your-wallet-address" } } } }
