Build a crypto whale-monitoring agent with Claude in 5 minutes
Connect Claude to the CoinLobster MCP server and it can watch live whale trades, funding, liquidations and named wallets across 15 exchanges plus on-chain, no API key to start. Here is the whole build.
Add the CoinLobster MCP server
CoinLobster exposes a keyless MCP endpoint. Add it to Claude Code with one command, or drop it into any MCP client config. Exact per-client steps (Claude desktop, Cursor, VS Code, Cline, Codex) are on the connect page.
claude mcp add --transport http coinlobster https://coinlobster.com/mcp
# or, in an MCP client config:
{
"mcpServers": {
"coinlobster": { "url": "https://coinlobster.com/mcp" }
}
}Ask it what whales are doing
That is it. Claude now has the live tools. Ask in plain language and it calls the right one (whale_radar, whale_flow, trade_context, liquidations, smart_money and more).
You: Which coins have unusual whale activity right now, and is it buying or selling?
You: Show me BTC whale flow for the last hour, broken down by exchange.
You: Before I touch SOL, what does the pre-trade picture look like?Make it act on a rule
Wrap the tools in a loop or a schedule and you have an agent: poll whale_radar, and when a coin crosses a threshold, have Claude summarise trade_context and post it to your channel. The tools return structured JSON, so the agent logic stays simple.

A free key raises the keyless rate limits; a Pro plan unlocks every $100K+ trade and custom alerts. See the API, keys and pricing.
What you can ask
- Which coins are whales unusually active on right now?
- Break down BTC whale flow by exchange for the last hour.
- What is the funding rate on SOL versus its own history?
- Give me the one-call pre-trade picture for ETH.
