Vaultguard Mcp

kota1026/quantum-shield

This connects Claude to Yearn V3 vault security analysis, though the repository is actually Quantum Shield, a post-quantum cryptography protocol for Ethereum, not a Yearn-specific tool. The codebase includes L1 Sepolia contracts for vault custody with dual NIST post-quantum signatures (ML-DSA-65 and SLH-DSA), a Rust API backend, and PostgreSQL for tracking lock/unlock operations. If you're auditing DeFi vaults or need AI assistance analyzing time-locked custody mechanisms with quantum-resistant cryptography, this could expose relevant data. The naming mismatch suggests the MCP implementation may wrap specific vault analysis features from the broader Quantum Shield project, but the actual MCP server code isn't visible in this source tree.

Quantum Shield

License: MIT Rust Solidity Next.js

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.
