MCP Billing Gateway SDK
MCP 计费网关
为任何 MCP 服务器添加 Stripe 订阅、按调用计费 和 x402 加密货币支付 功能 —— 无需编写任何计费代码。
MCP 计费网关是一个托管的计费代理,位于 AI 代理和您的 MCP 服务器之间。它会自动处理支付验证、使用量跟踪和层级强制执行。您只需注册服务器、设置定价计划,并将调用者指向代理 URL 即可。无需编写计费代码。

安装
pip install mcp-billing-gateway或者使用 uvx:
uvx mcp-billing-gatewayClaude Desktop 配置
添加到 ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) 或 %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"mcp-billing-gateway": {
"command": "uvx",
"args": ["mcp-billing-gateway"]
}
}
}Cursor 配置
添加到项目中的 .cursor/mcp.json:
{
"mcpServers": {
"mcp-billing-gateway": {
"command": "uvx",
"args": ["mcp-billing-gateway"]

工具
工具 | 描述 |
| 返回服务能力、支持的支付方式、功能和集成文档 |
本地 MCP 服务器提供服务发现功能。完整的计费功能在托管网关上运行 —— 请注册为运营商并通过它代理您的 MCP 服务器。
工作原理
AI Agent → MCP Billing Gateway → Your MCP Server
(billing enforced here)注册为运营商并获取 API 密钥
注册您的 MCP 服务器 URL 和定价计划
将调用者指向您的代理别名:
https://mcp-billing-gateway-production.up.railway.app/proxy/{your-slug}/mcp调用者通过 Stripe API 密钥或 x402 USDC 支付 —— 计费过程透明处理
功能
按调用计费 —— 按工具调用次数向调用者收费(法币或加密货币)
订阅 —— 带有调用限制的月度/年度 Stripe 计划
分级定价 —— 免费层级 + 基于使用量的付费层级
x402 微支付 —— AI 代理无需 API 密钥即可在 Base 链上使用 USDC 支付
运营商仪表板 —— 实时跟踪收入、使用量和调用者
MCP 传输 ——
/mcp/端点提供完整的 Streamable HTTP MCP 传输
快速入门
1. 注册为运营商
curl -X POST https://mcp-billing-gateway-production.up.railway.app/api/v1/operator/register \
-H "Content-Type: application/json" \
-d '{"email": "you@example.com", "name": "Your Name"}'响应:
{
"operator_id": "op_abc123",
"api_key": "bg_live_xxxxxxxxxxxx",
"message": "Operator registered successfully"
}2. 注册您的 MCP 服务器
curl -X POST https://mcp-billing-gateway-production.up.railway.app/api/v1/servers \
-H "Authorization: Bearer bg_live_xxxxxxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"name": "My MCP Server",
"upstream_url": "https://your-mcp-server.com/mcp",
"proxy_slug": "my-server"
}'3. 创建定价计划
curl -X POST https://mcp-billing-gateway-production.up.railway.app/api/v1/servers/{server_id}/plans \
-H "Authorization: Bearer bg_live_xxxxxxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"name": "Pay as you go",
"billing_model": "per_call",
"price_per_call_usd_micro": 10000,
"free_calls_per_month": 100
}'4. 将调用者连接到您的代理服务器
{
"mcpServers": {
"my-server": {
"url": "https://mcp-billing-gateway-production.up.railway.app/proxy/my-server/mcp",
"headers": {
"Authorization": "Bearer CALLER_API_KEY"
}
}
}
}支付方式
方式 | 适用对象 | 如何操作 |
Stripe 订阅 | 人类开发者 | 通过 Stripe Checkout 进行月度或年度计划 |
Stripe 按调用计费 | 人类开发者 | 每次工具调用消耗积分 |
x402 微支付 | AI 代理 | Base 链上的 USDC,无需 API 密钥 |
