CoinGecko

@coingecko what's the current price of Bitcoin and Ethereum in USD and EUR, and show me their 24-hour trading volume?

Bitcoin is currently trading at $43,287 USD (€39,841 EUR) with a 24-hour trading volume of $28.4 billion. Ethereum is at $2,264 USD (€2,083 EUR) with $15.7 billion in 24-hour volume. Both prices reflect the spot market across major exchanges as of the last API refresh. Market cap for BTC stands at $847B and ETH at $272B.

This example uses the Get Coin Prices tool to fetch multi-currency spot data. CoinGecko's free tier allows 10-30 calls per minute; if you're polling prices frequently across many coins, you'll hit rate limits quickly. Prices lag real-time by 1-3 minutes depending on exchange aggregation.

@coingecko pull the last 30 days of Bitcoin price history with daily granularity so I can chart the trend in our dashboard.

Retrieved 30 daily price points for Bitcoin spanning January 15 through February 13, 2025. The dataset includes UTC timestamps, closing prices in USD, market cap snapshots, and 24-hour volume for each day. Highest close was $45,120 on February 8; lowest was $41,003 on January 22. The data is formatted as a time series ready for charting or statistical analysis.

This example demonstrates the Get Coin Market Chart tool, which returns historical OHLC and volume data. The 30-day window is a common use case for trend analysis. Be aware that CoinGecko's historical granularity changes with the time range: hourly data is available for shorter windows, daily for longer ones. API key tier affects how far back you can query.

@coingecko compare the global crypto market cap today versus last week, and tell me if DeFi's share of total volume is growing.

Global crypto market cap is currently $1.68 trillion, up 4.2% from $1.61 trillion seven days ago. Total 24-hour trading volume sits at $89 billion. DeFi's share of that volume has grown from 11.3% last week to 12.8% today, indicating increased activity in decentralized exchanges and lending protocols relative to centralized platforms. Bitcoin dominance remains steady at 50.4%.

This synthesis example pairs the Get Global Market Data tool with the AI's ability to calculate percentage changes and interpret trends. CoinGecko aggregates data across thousands of coins and exchanges, so the snapshot is broad but not real-time. Use this for macro analysis, not for trading decisions requiring sub-minute precision.

When real-time treasury visibility matters more than spreadsheet exports

A 6-person web3 startup holds operating funds across ETH, stablecoins, and governance tokens. The CFO needs daily snapshots without logging into five wallets. This MCP wins because Get Onchain Token Prices pulls live USD values for any contract address, and Get Coin Market Chart gives you 90-day trend context in one call. The API key tier determines rate limits—free gets you 10-30 calls per minute, which covers a morning standup refresh but not a real-time dashboard. If your treasury sits in more than 20 positions or you need sub-minute updates, you'll hit the wall fast and need the paid tier. For weekly board decks and daily Slack digests, this is the cleanest path from contract address to dollar figure.

Why this MCP beats manual CoinGecko tabs for token vetting

An early-stage fund evaluates 40 token projects per quarter. Analysts copy-paste market cap, volume, and community stats into Notion during first-pass screening. Get Coin Details returns metadata, developer activity, and community metrics in one structured call—no browser, no formatting. Get Coin OHLC gives you 30-day price candles to spot pump-and-dump patterns before the partner meeting. The trade-off: CoinGecko's free tier caps you at 10,000 monthly calls, so if you're running this on every inbound pitch deck (100+ per month), you'll burn through that in week two. For funds closing 8-12 deals per year, this MCP turns a 20-minute tab-switching ritual into a 90-second AI summary. Worth the API key.

When pool data lookups need to happen in the support thread

A 12-person DeFi team fields 200 Discord questions per week about liquidity pool performance and token prices. Support reps toggle between Dune dashboards, Etherscan, and CoinGecko to answer "why did my pool APY drop?" Get Onchain Pool OHLCV and Get Onchain Pools by Address let the AI pull candle data and pool metrics without leaving the chat. The constraint: onchain endpoints only cover CoinGecko's supported networks (Ethereum, Polygon, Arbitrum, BSC, and a dozen others), so if your protocol lives on an obscure L2, you're out of luck. If 80% of your user questions map to mainnet or top-5 L2s, this MCP cuts average handle time from 4 minutes to under 90 seconds. That's 6 hours saved per week for a team already underwater.
