概覽

AI 產生的概覽

按次計費的鏈上資料 MCP 伺服器：代幣、錢包、NFT、交易、Gas 與風險查詢，以 Base 上的 USDC 結算，無需 API 金鑰。

可以做什麼
  • 查詢代幣價格、ERC-20 餘額、NFT 持有、交易歷史、Gas 費用與區塊
  • 建立錢包輪廓並掃描大額轉帳或增持活動
  • 評估代幣風險，並產出每項事實都附來源與檢查時間的代幣檔案
  • 在一次呼叫中跨最多 5 條鏈比較同一合約地址
  • 批次查詢餘額、NFT、價格與轉帳，每次最多 20 個地址或 50 個 id
  • 免費讀取能力清單與價格表
適用情境
適合助理需要鏈上加密資料做研究、盡職調查或監控，又不想申請資料商 API 金鑰，且呼叫方願意為每次呼叫支付少量 Base 上的 USDC 時使用。
執行需求
遠端 Streamable HTTP 端點，或透過 npx 執行 npm 套件作為連接同一託管伺服器的 stdio 橋接。無需帳號或 API 金鑰。付費呼叫需要 Base 上的 x402 USDC 付款：簽署 EIP-3009 授權並提供 payment-signature 標頭，stdio 橋接可設定 CORTEXCLOUD_PAYMENT_SIGNATURE。CORTEXCLOUD_BASE 可覆寫 API 位址。
安裝前請注意
多數工具收費：每次呼叫 0.004 至 0.040 USDC，批次工具按地址或 id 計費，重複或大批量呼叫會花費真實資金。付費呼叫需用錢包簽署 USDC 授權；伺服器只轉送 payment-signature 標頭，不持有資金也不簽章。查詢內容與付款標頭會傳送給第三方託管 API。免費工具為 cortex_capabilities 與 cortex_prices。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Cortexcloud，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

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。

交給代理程式安裝

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.jonahthan433%2Fcortexcloud/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。

README

@cortexcloud.org/mcp

MCP server for CortexCloud — pay-per-call on-chain data and intelligence for AI agents. Token, wallet, risk, whale, balance, NFT, transaction and cross-chain reads, settled in USDC on Base over x402. No API keys, no subscriptions, no signup.

Two ways to connect

1. Remote (recommended). The hosted server speaks Streamable HTTP and is always current:

json
{  "mcpServers": {    "cortexcloud": {      "type": "http",      "url": "https://api.cortexcloud.org/mcp"    }  }}

2. stdio bridge. This package, for clients that can only launch a local process:

json
{  "mcpServers": {    "cortexcloud": {      "command": "npx",      "args": ["-y", "@cortexcloud.org/mcp"]    }  }}

The bridge is a transport adapter, not a second implementation: it forwards tools/list and tools/call to the hosted server, so tools, schemas and prices can never drift from the API.

Tools

17 tools, served from the live registry:

  • Paid (15) — cortex_token_intel ($0.030), cortex_cross_chain_compare ($0.040), cortex_whale_alerts ($0.030), cortex_token_risk ($0.020), cortex_wallet_intel ($0.006), and the $0.004 data routes: cortex_token_price, cortex_token_balances, cortex_nft_ownership, cortex_tx_history, cortex_gas_oracle, cortex_block, plus the batch tools cortex_aggregate_balances, cortex_aggregate_nfts, cortex_aggregate_prices, cortex_aggregate_tx_history (up to 20 items per call).
  • Free (2) — cortex_capabilities (every route, chain and price) and cortex_prices (the price table).

The authoritative list is always GET https://api.cortexcloud.org/v1/capabilities, or cortex_capabilities over MCP.

How payment works

A paid tool call without payment returns the x402 challenge inside the tool result: price, payee, asset, network, and the endpoint to call. Nothing is charged and no wallet is needed to read it.

To settle, the caller signs an EIP-3009 USDC authorization and replays the request with the payment-signature header. Over MCP the server relays that header to the API unchanged; it holds no funds and never signs. Over stdio, forward an existing signature with:

bash
CORTEXCLOUD_PAYMENT_SIGNATURE=<base64 header> npx -y @cortexcloud.org/mcp

For a complete paid flow from code, use the REST reference client — 402 -> sign -> 200 in one file:

https://api.cortexcloud.org/examples/paid_client.py

Env

VariableDefaultMeaning
CORTEXCLOUD_BASEhttps://api.cortexcloud.orgAPI base; the bridge connects to <base>/mcp
CORTEXCLOUD_PAYMENT_SIGNATURE—Optional x402 payment header forwarded on every call

Verified behaviour

  • initialize advertises protocol 2025-06-18; the upstream server reports version 0.5.0.
  • tools/list returns 17 tools.
  • cortex_capabilities returns the live catalog with no payment.
  • cortex_token_price without payment returns the 402 challenge, not an error.
