2 tools offered to AI assistants

  • check_recipient_lookalike · Free, offline, read-only: before sending crypto, check whether the recipient address is a lookalike (same first/last hex characters, different middle) of any address you trust, and whether its EIP-55 checksum is valid. Address poisoning sto
  • onchain_check_info · How to buy the on-chain check (scans the sender's real transfer history on Ethereum/Base/Avalanche for poisoning transfers and lookalikes) via x402 for 0.005 USDC. Does not pay.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
