Monetize any MCP server: x402 paywall, pay-per-call billing in USDC on Base, agent marketplace.
远程 MCP 网关，让助手发现付费工具、注册并定价自己的 MCP 服务器，并查看 Base 上 USDC 按次付费的收益
Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/io.github.geoacpfilho%2Fpaygate-monetize-monetization-x402/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}Monetization gateway for Model Context Protocol servers. Put any MCP server behind a pay-per-call toll that AI agents can settle autonomously — no signup, no API keys, no human in the loop.
Live endpoint: https://paygate-mcp.rendercriativo.workers.dev/mcp
An agent calls a tool. If the tool is monetized, PayGate answers with an x402 v2 payment challenge instead of the result. The agent signs a USDC transfer authorization, retries, and gets its answer. Settlement happens on Base; the developer never touches payment code.
Payment is verified before the tool runs and settled after it returns. If the tool fails or returns an error, nothing is charged.
Discovery is free. Ask PayGate what is for sale:
Calling a monetized tool without payment returns a spec-compliant challenge — a tool result with isError: true whose structuredContent holds the PaymentRequired object:
Sign an EIP-3009 TransferWithAuthorization using exactly the domain in extra, then retry the call with the payment attached under params._meta["x402/payment"]. The settlement receipt comes back in _meta["x402/payment-response"].
The USDC EIP-712 domain name is
"USD Coin"on Base mainnet and"USDC"on Base Sepolia. Using the wrong one makes every signature fail verification.
A working reference client is in scripts/pay-test.mjs:
The paying wallet needs USDC on Base — but no ETH: gas is covered by the facilitator.
Both x402 transports are supported. HTTP clients can use the base64 PAYMENT-REQUIRED / PAYMENT-SIGNATURE / PAYMENT-RESPONSE headers instead of the MCP _meta binding.
The whole seller lifecycle is exposed as MCP tools, so an agent can run it end to end — tell your assistant to monetize your server and it can do everything below on its own:
Buyers pay your wallet directly on-chain. PayGate never holds your funds — there is no payout to wait for, no balance to withdraw, and no commission on direct payments. Your server is never modified: PayGate forwards initialize, tools/list, resources/list and prompts/list for free and charges only on tools/call.
The same operations exist as REST (POST /api/register, PUT /api/me/tools, GET /api/me/earnings) if you prefer curl:
GET /health/x402 reports whether the payment rail is actually able to charge:
Runtime values live in wrangler.jsonc (vars) and Cloudflare secrets.
Base Sepolia needs no credentials: the public facilitator at https://x402.org/facilitator settles testnet USDC for free — the cheapest way to try the whole flow.
Built on Cloudflare Workers, Hono, and D1.

Find a paid tool that does something you cannot do yourself. Use when the user needs a capability you lack and is willing to pay per use, or asks what paid tools, APIs or data sources are available. Returns every tool on the market with its price per call in USD and the endpoint to call it. Browsing is free and needs no key.
searchmax_price_usdverified_onlyStart charging for an MCP server the user owns. Use when they want to monetize, sell, charge for, get paid for, put a price on, or make money from a server, API or tool. Buyers pay their wallet DIRECTLY on-chain — PayGate never holds the money, so there is no payout to wait for, no balance to withdraw and no commission taken. Their server is never modified and needs no payment code. Tools are imported automatically, so it must be publicly reachable over HTTPS and answer tools/list. Returns a proxy URL and a secret api_key shown only once; save it, every other seller tool needs it.
name必填emailwallet_addressdefault_price_usdstripe_account_idtarget_server_url必填Reprice or unlist something the user already sells. Use when they want to raise, lower or change a price, make a tool free, pause selling it, or take it off the market. Requires the api_key from register_server.
api_keyis_activeprice_usdtool_name必填Report how much the user has earned selling their tools. Use when they ask about sales, revenue, income, how much they made, how many calls were paid, or which tool sells best. Returns paid calls, gross revenue, commission and net revenue, broken down per tool. Requires the api_key from register_server.
api_keyReview what the user currently has for sale. Use when they ask what they are selling, what their prices are, where their money goes, or want to check their listing before changing it. Returns the proxy URL, payout destination, commission rate and every listed tool with its price. Requires the api_key from register_server.
api_keyProve the user owns the server they listed, earning a trusted badge in the marketplace. Use after they have published their verification token at /.well-known/paygate-verify on the server's domain. PayGate fetches that URL and confirms the token matches. Verified sellers can be filtered for by buyers, so this directly increases how often their tools get chosen. Requires the api_key from register_server.
