Crypto Data MCP Server

What does Crypto Data MCP Server do?

Crypto Data MCP Server is a persistent crypto data MCP server built on Apify Standby, designed to feed live market intelligence directly into AI agents via the Model Context Protocol. Instead of one-shot scraping, it runs as a long-lived HTTP server that your AI assistant queries on demand — delivering real-time kimchi premium, DeFi yields, ETF flows, Fear & Greed index, funding rates, and market overview without any API keys or setup. As a native Model Context Protocol crypto integration on Apify, it stays warm and responds in milliseconds, making it the easiest path to plug live crypto context into Claude Desktop, GPT, or any MCP-compatible agent.

Important: This is a server actor, not a one-shot scraper. Do NOT click "Run" — use the Standby URL to connect your AI agent. Clicking "Run" starts a short-lived instance that will time out.

Why use Crypto Data MCP Server?

AI crypto data integration has never been simpler — no credential management, no infrastructure, no polling loops.

• AI trading agents — inject live funding rates, ETF flows, and Fear & Greed scores into automated strategy signals without managing API keys yourself
• Claude Desktop / ChatGPT plugins — ask "what's BTC fear & greed today?" and get a live answer in chat, powered by this MCP server
• Crypto research pipelines — pull structured market data on demand into notebooks, dashboards, or LLM chains
• Crypto chatbots — add live DeFi yield data and kimchi premium to any LLM application without backend work
• Quantitative analysts — fetch funding rate spreads across CEXs and ETF flow signals as clean JSON, ready for downstream processing

How to use Crypto Data MCP Server

1. Open the actor page and click the Integrations tab
2. Copy your personal Standby URL (format: https://xxxxxxxxxxxxxxxx.apify.actor)
3. Add the server to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "crypto-data": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://YOUR_STANDBY_URL/mcp/v1"]
    }
  }
}

4. Restart Claude Desktop — the 6 crypto tools appear automatically in the tools panel
5. Ask Claude anything: "What are the top DeFi yields above 10% APY?" — it calls the MCP server live

Cost estimation

This actor runs in Standby mode — you pay only for compute time while the server is active.

Usage Pattern	Estimated Cost
Occasional queries (fewer than 10/day)	~$0.01–0.05/day
Active AI agent (50–200 queries/day)	~$0.10–0.30/day
Heavy pipeline use	~$0.50+/day

Standby actors bill per second of active compute. Idle time is not charged.

FAQ

Do I need an Apify API token to use the MCP tools? No. Once the actor is running via its Standby URL, your AI agent connects directly to the MCP endpoint. No Apify credentials are passed in tool calls.

What data sources does it use? CoinGecko (market overview), DefiLlama (DeFi yields), SoSoValue (ETF flows), Alternative.me (Fear & Greed), and public exchange APIs (funding rates). No paid API keys required.

Can I use this with ChatGPT or other LLMs? Yes. Any MCP-compatible client can connect. For non-MCP setups, you can also call the REST endpoints directly via the Standby URL.

Disclaimer: Data is sourced from public APIs and provided for informational purposes only. Nothing in this actor constitutes financial advice. Always verify data before making trading decisions.
