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.
Feed your own logic
Want your agent to run its own indicators? Ask for the near-live price bars (price_candles) and it gets clean OHLCV back to compute whatever it trusts. Wiring this around an existing bot as a check is its own walkthrough: confirm your bot with CoinLobster.
Go further
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.
