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 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

RoutePriceWhat
GET /api/basic?url=...freelexical verdict + findings
GET /v1/check?url=...&url=...0.005 USDC (x402 v2 exact, eip155:8453)full check, 1-10 URLs
GET /brands.jsonfreethe official-domain list we use
GET /openapi.json, /.well-known/x402.jsonfreediscovery

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.
