Quantumguard tools

No tool declarations could be read from the package source. They show once the server is installed.

How Quantumguard compares

Against every graded Security MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score
92/100
higher than 95% of 915 Security servers

Install Quantumguard in Claude Code, Cursor or VS Code

Runs npx -y quantumguard-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Quantum Shield

Post-quantum asset protection protocol for Ethereum using NIST-standardized cryptography

What is Quantum Shield?

Quantum Shield protects smart contract assets against quantum computing threats using NIST FIPS 204 (ML-DSA/Dilithium) and FIPS 205 (SLH-DSA/SPHINCS+) dual post-quantum signatures, combined with a decentralized Prover Pool, VRF-based selection, and time-locked custody.

Key Features

  • Dual PQC Signatures — ML-DSA-65 + SLH-DSA for defense-in-depth
  • Prover Pool — Decentralized verification with stake-weighted selection via VRF
  • Time-Locked Custody — 24h normal unlock, 7-day emergency path with bond
  • Observer Network — Independent challenge system with quadratic slashing
  • On-Chain Governance — veQS token voting, security council, insurance fund
  • 11 Sub-Applications — Consumer, Prover, Observer, Explorer, Enterprise, Governance, Admin
