How to Set Up and Use Crypto News API
The cryptocurrency.cv MCP server gives AI assistants real-time access to a free crypto news aggregator covering 200+ sources across Bitcoin, Ethereum, DeFi, Solana, and altcoins — no API key required for basic news endpoints. It exposes 40 MCP tools spanning news retrieval, AI-powered sentiment analysis, entity extraction, market data (prices, OHLC, Fear & Greed Index), trading signals, social intelligence, and regulatory tracking. With 662,000+ historical articles archived since 2017, it is the most comprehensive free crypto news source available for AI agents.
Prerequisites
- Node.js 18 or later (for npx-based installation)

AI-powered tools (summarize, sentiment, ask) return errors about missing API keys
Ensure GROQ_API_KEY is set in the env block of your MCP configuration. Get a free key at console.groq.com — no billing is required for the free tier.
npx fails to install the package or returns a 404 error
Verify the package name is @anthropic-ai/mcp-server-crypto-news. Ensure you have Node.js 18+ and npx is working: run npx --version. Clear the npx cache with npx clear-npx-cache if needed.
The server returns no results for a specific cryptocurrency search
Use standard ticker symbols or full names in search queries (e.g., 'BTC', 'Bitcoin', 'Ethereum'). The /api/search endpoint supports full-text search — try broader terms if narrow queries return empty results.
