Coinlobster Gemini Extension MCP Server

CoinLobster Gemini CLI Extension

See what whales see, inside Gemini CLI. Live whale trades from 15 crypto exchanges, Hyperliquid and Ethereum, Base and Arbitrum DEX swaps, Smart Money Radar, outcome-scored signals, market snapshots and news sentiment.

Install

One line, no account, no key. Install the extension:

gemini extensions install https://github.com/CoinLobster/coinlobster-gemini-extension

Or point Gemini CLI at the hosted MCP server directly, without the extension:

gemini mcp add --transport http coinlobster https://coinlobster.com/mcp

Or add it to your Gemini CLI settings:

{
  "mcpServers": {
    "coinlobster": { "httpUrl": "https://coinlobster.com/mcp" }
  }
}

httpUrl is the streamable-HTTP field. url would open an SSE connection, which this server does not serve.

Free and keyless: BTC/USD live in full, plus every $1M+ trade on any coin live. Other coins arrive 15 minutes delayed.

Try asking

• "What are whales doing with BTC right now?"
• "Which coins have unusual whale activity in the last 4 hours?"
• "Show the last 10 whale signals that fired and what price did after each."

Tools

Call tools/list to see what your server actually exposes. Today it serves the tools below, plus whale_tape, a deprecated alias of whale_trades kept so older clients keep working.

Whale flow

Tool	What it returns
whale_trades	Live whale trades across 15 CEX, Hyperliquid and 3 chains, newest first
whale_radar	Coins with unusual whale flow right now (1h/4h/24h)
whale_flow	Hourly buy vs sell whale volume for one coin, CEX and DEX split
whale_context	Whether a coin's flow is unusual against that coin's own logged history
flag_outcomes	Fired signals with fire-time price and what price did after

Market state

Tool	What it returns
market_snapshot	Price, 24h stats, funding, open interest, liquidations for one pair
market_overview	Market-wide scan: totals, 24h whale net flow, BTC risk regime
trade_context	The one-call picture for one pair
market_screener	Filter every recorded pair by funding and open-interest bands, each read against that pair's own history
funding_matrix	Per-venue funding for one pair, with next payout where published
squeeze_score	0-100 crowding read and the overexposed side (developer plan)
crypto_news	Headlines plus a sentiment score for a coin and the macro picture

Forced closes

Tool	What it returns
liquidations	Liquidations for one pair, long vs short breakdown
market_liquidations	The market-wide 24h picture, split long vs short
liq_zones	Projected liquidation levels (a model, not executed trades)
defi_liquidations	Aave V3 lending liquidations, both wallets named

Perp liquidations and lending liquidations are different events and are never added together.

On-chain and named wallets

Tool	What it returns
onchain_whales	DEX whale swaps on Ethereum, Base and Arbitrum, with the wallet
dex_wallet	One address: its DEX swaps and net flow per token
defi_summary	Per-chain DEX volume and TVL, top tokens
hl_whales	Hyperliquid fills with the wallet named on both sides
hl_board	Tracked Hyperliquid accounts: equity, open size, leverage, bias
hl_wallet	One Hyperliquid account: positions, leverage, liquidation prices, fills

Recorded history

Tool	What it returns
market_history	The daily archive: funding, open interest, price, liquidation totals
market_extremes	Records and top/bottom 5% against each pair's own history

More depth

A free API key does not lift the MCP caps. It is a one-off 1,000-credit grant that unlocks the metered REST endpoints at /api/ai/v1/*, roughly 20 to 100 calls in total.

Full MCP depth (live feed on every pair, unlocked radar magnitudes, non-BTC market_snapshot, 30-day flow windows instead of 7) needs an active developer plan (Builder $29/mo, Growth $99, Scale $249) sent as X-API-Key. One plan covers both full-depth MCP and the REST credits, on one shared account balance. A tool call costs 2x its mirrored REST endpoint: 40 to 100 credits by tool. Keyless calls, discovery, failed calls and no-data answers cost nothing.

CoinLobster Pro ($9/mo) is the coinlobster.com website subscription (live feed, alerts, whale radar). It grants no MCP depth and no API access.
