Data Sources

This MCP server connects to the J4Y backend which aggregates:

• 170+ news sources (RSS feeds, The Block, CoinDesk, etc.)
• 50+ KOL Twitter accounts (Chinese + English)
• Real-time market data (CoinGecko, Fear & Greed Index)
• On-chain data via DeBank API

Why MCP Server?

Unlike prompt-based skills that rely on the host LLM to execute commands, this MCP server:

• Executes real API calls - Tools directly call the J4Y backend
• Returns real data - BTC/ETH prices, Fear & Greed Index are from live sources
• Works on any MCP-compatible platform - OpenClaw, Claude Desktop, Cursor, etc.
