crypto-sentiment-x402 MCP

An MCP server providing pay-per-call crypto sentiment analysis for AI agents. It aggregates news sentiment from 9 outlets and the Fear & Greed Index over a 72-hour window using VADER analysis with crypto slang. Agents discover the API, receive an HTTP 402, pay in USDC on Base, and retrieve the data without needing API keys or subscriptions.
