Crypto Data MCP Server

Real-time crypto market data exposed as an MCP (Model Context Protocol) server. Connect Claude Desktop or any MCP-compatible AI agent directly — no scraping, no API keys, no setup required.

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.
