Looking at the source repository, this appears to be mispackaged. The repo is actually Quantum Shield, a post-quantum cryptography protocol for Ethereum using NIST-standardized signatures, not a crypto market data MCP server. The codebase includes Rust backend APIs, Solidity contracts on Sepolia, and a Next.js frontend for asset protection workflows. There's no MCP server implementation visible in the source. If you need real-time crypto prices or DeFi analytics, this isn't it. If the maintainer intended to publish an MCP server from this repo, it either lives in an undocumented path or the package mapping is incorrect. Worth checking with the author before trying to integrate.
