Track large on-chain whale transactions on Ethereum and Base. x402 micropayment.
Most developer tooling work still happens through a UI a human drives. Whale Alert API MCP server moves it into the conversation instead. Track large on-chain whale transactions on Ethereum and Base. x402 micropayment.
Whale transaction tracker -- large on-chain transfers with sender, value, USD estimate. Market-moving alerts. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
The server publishes 1 tool. What each one is for:
crypto_track_whale_transactions — POSTAmong the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Whale Alert API's toolset — crypto_track_whale_transactions — is a fair guide to whether it matches your workflow. It is maintained by Br0ski777; worth a glance at recent repository activity before you build anything load-bearing on it.
