What it can do

check_crypto_link
Free, read-only, no network fetch: before connecting a wallet or signing, check a URL/domain for crypto phishing signs (lookalike or typosquat of ~60 wallets/exchanges/dapps, punycode, free hosting, bait words). Returns verdict official | no_red_flags | caution | suspicious | dan
full_report_info
How to buy the full link check via x402. Does not pay.

Common questions

Is Crypto Link Check safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Crypto Link Check

Is that MetaMask / Phantom / Ledger / exchange link real? Check it before you (or your agent) connect a wallet or sign anything.

October 2026 alone brought fake Phantom, Jupiter and Bitget browser extensions, a hijacked NGRAVE push alert that sent users to a seed-phrase page, and exchange phishing mails. AI agents can now trade from exchange accounts and pay for things on their own, so they click links too. This tool gives them (and you) a quick, read-only second opinion.

Free, offline: CLI and MCP server that compare a link with the official domains of ~60 wallets, exchanges and dapps and flag lookalike characters (0/o, rn/m, Cyrillic), typosquats, punycode, free hosting and bait words like "claim" or "sync".
Free API + remote MCP: https://crypto-link-check.nextill-pos.workers.dev
Paid full check (optional, 0.005 USDC via [x402](https://x402.org) on Base): adds domain registration age (RDAP), DNS, redirect tracing and one fetch of the page scanned for seed-phrase prompts and token-approval drainer code. 1-10 URLs per call.

It never asks for keys or seed phrases. Verdicts are heuristics, not guarantees.

CLI

npx devx-link-check phantorn.app metamask.io

verdict: dangerous phantorn.app

[danger] phantorn.app spells the official phantom.app with lookalike characters ...

verdict: official metamask.io

Exit code: 0 official / no red flags, 2 caution / suspicious / dangerous, 1 error. --json for machine output.

MCP

Local (stdio), runs offline:

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

Remote (streamable HTTP, no key): https://crypto-link-check.nextill-pos.workers.dev/mcp

Tools: check_crypto_link(url) and full_report_info().

HTTP API

Route	Price	What
`GET /api/basic?url=...`	free	lexical verdict + findings
`GET /v1/check?url=...&url=...`	0.005 USDC (x402 v2 `exact`, `eip155:8453`)	full check, 1-10 URLs
`GET /brands.json`	free	the official-domain list we use
`GET /openapi.json`, `/.well-known/x402.json`	free	discovery

The paid route answers 402 with a PAYMENT-REQUIRED header; any x402 client can pay. Settlement happens only after the report is produced. Humans can pay from a browser wallet on the web page. Terms: /terms.

Verdicts: official, no_red_flags, caution, suspicious, dangerous. Same-name-different-TLD domains are only caution because the brand may own them.

Official-domain list

cli/src/brands.js. It is curated by hand and incomplete. PRs that add brands or official domains (with a source) are welcome.
