crypto
crypto_track_whale_transactions
Use this when you need to track large on-chain transactions (whale movements) on Ethereum or Base. Returns recent high-value transfers in JSON. 1. transactions: array of whale transfers sorted by value descending 2. from: sender wallet address 3. to: receiver wallet address 4. valueEth: transaction value in ETH 5. valueUsd: estimated USD value at time of transfer 6. txHash: transaction hash for on-chain verification 7. blockNumber: block number of the transaction 8. timestamp: when the transaction occurred Example output: {"transactions":[{"from":"0xab...","to":"0xcd...","valueEth":500.0,"valueUsd":1552500,"txHash":"0xef...","blockNumber":19845632,"timestamp":"2026-04-13T11:22:00Z"}],"chain":"ethereum","minValue":100,"totalFound":8} Use this FOR detecting market-moving whale activity and smart money flows. Essential for trading signal generation and on-chain intelligence. Do NOT use for wallet balance -- use wallet_get_portfolio instead. Do NOT use for token prices -- use finance_get_token_price instead. Do NOT use for holder distribution -- use token_get_holder_analysis instead.

Whale Alert API — questions

Answers built from our own checks of this server.

What can Whale Alert API do?
It exposes 1 tools, read directly from the server on our last check. Among them: crypto_track_whale_transactions. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Whale Alert API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 32 ms. The bar chart above shows every period we have measured.
How do I connect Whale Alert API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Whale Alert API need an API key?
No. Whale Alert API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Whale Alert API?
It answers our handshake in 32 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Whale Alert API open source?
Yes — it is published under the MIT licence, written in TypeScript, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
