Introducing Crypto Data MCP: Free real-time crypto data for your AI tools

A free, open-source MCP server that pipes live cryptocurrency data straight into Claude Code, Cursor, and any MCP-compatible client. No API keys. No rate limits on the free tier. Just data.

What it is

Crypto Data MCP is a Model Context Protocol server that gives your AI tools direct access to cryptocurrency market data. Prices, market caps, volume, historical charts, token metadata — all available as structured tool calls inside your coding environment.

Ask Claude Code to check the price of ETH. Ask it to compare BTC's 30-day price action against SOL. Ask it to pull market overview data for the top 50 tokens. It just works.

Why we built it

The MCP ecosystem has 17,000+ servers. Most are abandoned weekend projects. The crypto category is especially bad — broken endpoints, stale data, zero documentation. If you're building anything that touches crypto markets, you need a server that actually works and stays maintained.

We built the server we wanted to use ourselves. It's fast, reliable, and backed by production-grade data sources. The free tier covers 90% of what most developers need. The pro tier covers the rest.

The tools

Five tools ship with the free tier:

get_price — Current price, 24h change, market cap, and volume for any token. One call, one token.
get_prices — Batch pricing for up to 50 tokens in a single request. Same data as get_price, but in bulk.
get_market_overview — Top tokens ranked by market cap with global market stats. The 30-second snapshot of the entire crypto market.
get_token_info — Deep metadata on any token: description, links, supply data, genesis date, categories, and contract addresses across chains.
get_historical_prices — OHLC price history with configurable timeframes. Feed it into analysis, charts, or backtesting workflows.

Install in 30 seconds

Add this to your Claude Code MCP config (~/.claude/mcp.json):

{
  "mcpServers": {
    "crypto-data": {
      "command": "npx",
      "args": ["-y", "crypto-data-mcp"]
    }
  }
}

Restart Claude Code. That's it. No API key needed for the free tier.

What's coming with Pro

The free tier handles spot data. Pro ($19/mo) unlocks the real-time and on-chain layer:

WebSocket price feeds — Sub-second price updates streamed directly into your tools. No polling.
DEX data — Liquidity pools, swap volumes, and pair analytics across Uniswap, Raydium, and major DEXs.
On-chain analytics — Whale wallet tracking, token flow analysis, and smart money signals.

Pro launches later this month. Free tier users get early access pricing.

Open source

The server is fully open source. Star it, fork it, contribute to it: github.com/Wh0FF24/crypto-data-mcp

Issues and PRs are welcome. If you want a tool added to the free tier, open a feature request.
