Crypto Market Data

Crypto Market Data

[GitHub stars] [Last commit] [PRs welcome] [AI agent friendly]

Live dashboard: https://nirholas.github.io/crypto-market-data/

Live cryptocurrency and DeFi market dashboard with data from CoinGecko and DeFiLlama.

Cryptocurrency prices and market data. That's it! With a basic UI. I originally built this within Lyra Web3 Playground and I thought it might be helpful for those looking for something very simple, a good learning experience to build + deploy, or maybe you're like me and just enjoy building and sharing simple yet useful creations. Live data, hooked up to CoinGecko and Defillama.

Features

• 🪙 Cryptocurrencies - Top coins by market cap with 7-day sparklines
• 🏦 DeFi Protocols - Protocol TVL rankings from DeFiLlama
• 📈 Yields - DeFi yield farming opportunities
• ⛓️ Chains - Blockchain TVL comparison
• 🌙 Dark Mode - Toggle between light and dark themes
• 📱 Responsive - Works on desktop and mobile

Quick Start

# Install dependenciesnpm install
# Start development servernpm run dev
# Build for productionnpm run build

Deploy to GitHub Pages

Pushes to main are built and deployed automatically by the GitHub Actions workflow in .github/workflows/deploy.yml. The live site is at nirholas.github.io/crypto-market-data.

To build and host the static output yourself:

npm run build# Serve or upload the dist/ folder

MCP Server

This repo also bundles a Model Context Protocol server in mcp-server/ that exposes the same CoinGecko and DeFiLlama data to AI assistants (Claude Desktop, Cursor, and other MCP clients): live prices, OHLCV candles, trending coins, coin search, DeFi protocol/chain TVL, yields, and stablecoin supplies.

See mcp-server/README.md for the full tool list, build instructions, and client configuration.
