概览

AI 生成的概览

按次付费的链上数据 MCP 服务器：代币、钱包、NFT、交易、Gas 与风险查询，以 Base 上的 USDC 结算，无需 API 密钥。

可以做什么
  • 查询代币价格、ERC-20 余额、NFT 持有、交易历史、Gas 费用与区块
  • 生成钱包画像并扫描大额转账或增持活动
  • 评估代币风险，并生成每条事实都带来源与检查时间的代币档案
  • 在一次调用中跨最多 5 条链比较同一合约地址
  • 批量查询余额、NFT、价格与转账，每次最多 20 个地址或 50 个 id
  • 免费读取能力清单与价格表
适用场景
适合助手需要链上加密数据做调研、尽职调查或监控，又不想申请数据商 API 密钥，且调用方愿意为每次调用支付少量 Base 上的 USDC 时使用。
运行要求
远程 Streamable HTTP 端点，或通过 npx 运行 npm 包作为连接同一托管服务器的 stdio 桥接。无需账号或 API 密钥。付费调用需要 Base 上的 x402 USDC 支付：签署 EIP-3009 授权并提供 payment-signature 请求头，stdio 桥接可设置 CORTEXCLOUD_PAYMENT_SIGNATURE。CORTEXCLOUD_BASE 可覆盖 API 地址。
安装前请注意
多数工具收费：每次调用 0.004 至 0.040 USDC，批量工具按地址或 id 计费，重复或大批量调用会花掉真实资金。付费调用需用钱包签署 USDC 授权；服务器只转发 payment-signature 请求头，不持有资金也不签名。查询内容与支付请求头会发送给第三方托管 API。免费工具为 cortex_capabilities 与 cortex_prices。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Cortexcloud，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

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。

交给智能体安装

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.jonahthan433%2Fcortexcloud/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。

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

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.
