这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。

它能帮你做什么

我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。

安装

选择你使用的 AI 应用,然后复制设置。

安装之前

你需要

  • 在云端运行无需安装任何东西,通过互联网连接
  • npm已安装 Node.js(用于 npx 命令)

你用的是哪个应用?

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。

适用于网页版、桌面版和手机版 Claude:

  1. 打开 Settings → Connectors
  2. 点击 Add custom connector
  3. 粘贴下面的地址,然后点击 Add
  4. 如果要求登录,请登录作者的服务

常见问题

Address Poisoning Check 安全吗?

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。

它需要哪些密钥或代码?

注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端?

两种方式都可以:安装在你的电脑上,或者连接云端版本。

它还在维护吗?

GitHub 仓库最后更新于–,最新版本(1.1.0)于7天前进入注册中心。

哪些应用可以使用它?

支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

有什么可以替代它?

Address Poisoning Check

Is this the address you meant? Address poisoning plants a lookalike address (same first and last characters, different middle) in a wallet's history with a zero-value, dust or fake-token transfer, and waits for the owner (or their AI agent) to copy it. Bitquery counted about $76M stolen on Ethereum alone in the 12 months to July 2026.

This repo has three pieces, all read-only (we never ask for keys and never move funds):

WhatCost
CLI / stdio MCP devx-address-poisoning-checkOffline: is the recipient a lookalike of any address you trust? Is its EIP-55 checksum valid? Nothing leaves your machine.free
Remote MCP https://address-poisoning-check.nextill-pos.workers.dev/mcpSame offline check as a hosted MCP toolfree
HTTP API GET /v1/check?from= &to= On-chain: scans the sender's real transfer history (Ethereum + Base, optional Avalanche) and flags lookalikes of real counterparties, zero-value / dust / fake-token poisoning transfers (with tx hashes), recipients that only ever appeared through such transfers, and senders that were already poisoned. Returns `ok \caution \danger` and the address you probably meant.0.005 USDC via x402 on Base

Live: https://address-poisoning-check.nextill-pos.workers.dev

CLI

npx devx-address-poisoning-check 0xd9A1C3788D81257612E2581A6ea0aDa244853a91 --known 0xd9A1b0B1e1aE382DbDc898Ea68012FfcB2853a91

DANGER: Looks like 0xd9a1...3a91 (same first 4 / last 6 hex chars) but is a different address. Classic address-poisoning lookalike.

Exit code 2 on danger, so it can gate scripts and agent payment flows.

MCP

Claude Desktop / Cursor (stdio):

{ "mcpServers": { "address-poisoning-check": { "command": "npx", "args": ["-y", "devx-address-poisoning-check", "mcp"] } } }

Or remote (streamable HTTP): https://address-poisoning-check.nextill-pos.workers.dev/mcp

Tools: check_recipient_lookalike (free), onchain_check_info (how to buy the on-chain check; does not pay).

Paid on-chain check (x402)

GET https://address-poisoning-check.nextill-pos.workers.dev/v1/check?from=0x...&to=0x...[&chains=ethereum,base,avalanche]
  • Answers 402 with an x402 v1 body (X-PAYMENT, network base) and a v2 PAYMENT-REQUIRED header (PAYMENT-SIGNATURE, eip155:8453). Both work.
  • 5000 atomic USDC (0.005 USDC) to 0xB3cDDccEe6B150c8efFD55B961afc0Ecefe7f247, settled through the Coinbase CDP facilitator, listed in the CDP x402 Bazaar.
  • Settled only after the report is produced; bad input or data-source errors are not charged.
  • Data: Ethereum/Avalanche via the Routescan explorer API (last 300 token transfers + 150 transactions of the sender); Base via the Coinbase CDP SQL API (last 14 days of all ERC-20 transfers, including unknown/fake tokens), falling back to public RPC logs for a shorter window. Typical paid response: about 1-2 s. Data collection has a 3.5 s budget; if a source is slow you still get a report with "partial": true and the scanned window stated per chain in chains[].window. It is a heuristic over a window of public data: always confirm the full address with the payee.

Example (the May 2024 $68M WBTC case): from=0x1E227979f0b5BC691a70DEAed2e0F39a6F538FD5&to=0xd9A1C3788D81257612E2581A6ea0aDa244853a91 returns danger / possibly_already_poisoned: the victim did send real value to that address, but it first appeared in their history through a zero-value transfer.
