Pay-per-call research tools for AI agents, paid via x402 USDC. Remote MCP, one free tool.
遠端 MCP 伺服器，提供按次計費的網頁、網域、GitHub、加密代幣、股票、天氣與公共資料研究工具，透過 x402 以 Base 上的 USDC 結算。
Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。
把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/io.github.foxxx009%2Fx402-tools-mcp/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。把它新增到你客戶端的 mcpServers 設定中。

}An MCP server that gives any AI agent six research and data tools, paid per call in USDC on Base through x402.
No API keys. No subscription. No monthly minimum. You pay a cent or two when your agent actually calls a tool.
Agent sandboxes are frequently firewalled from the open web, and the usual
workaround — an API-key-gated scraping service — means a subscription, an
account, and a monthly floor you pay whether or not you use it. x402 removes
all three: the server answers 402 Payment Required, the client signs a USDC
transfer authorisation, and the call proceeds. That is the whole handshake.
1. Fund a wallet. Any Base wallet with a few dollars of USDC. It needs no ETH — gas is paid by the settlement facilitator.
2. Export the key.
3. Register the server with your MCP client:
Or run it locally:
X402_BASE_URL lets you point the same server at your own x402 seller.
Only two things: the tool arguments, and an EIP-3009 signature authorising a USDC transfer for the quoted amount. The private key never leaves the process. Signing is local; settlement happens on Base.
X-PAYMENT; the 402 response always
states the exact amount before you pay anything.repo_diligence and web_brief are priced higher because they do real
multi-request work. Call them deliberately.Prefer not to run anything locally? The same service is exposed as a remote Streamable HTTP MCP endpoint:
Add it to any MCP client (Claude Desktop, Cursor, etc.) as a remote server
URL. free_url_check runs without payment; paid tools answer HTTP 402 with
x402 payment requirements and settle in USDC on Base when an x402-capable
client retries. Listed in the official MCP Registry as
io.github.foxxx009/x402-tools-mcp.

Use to decide whether to depend on or contribute to a repo before trusting it.
repo必填$0.02 per call — Multi-source research brief from 1–3 URLs. For each source extract title, meta description, key sentences (numbered/quoted/date-or-figure-bearing) and outbound links. Returns a structured, citable brief other agents can consume without their own web access.
