Feature & Specification Comparison

Specification	Volta MCP Server iamredmh Security	Pqc Tools quantakrypto Security
Summary	Burn-after-read encrypted notes for AI agents. Create and read self-destructing notes via Volta Notes with AES-256-GCM E2E encryption — the decryption key never leaves the URL fragment. Secure credential handoff between users and agents without secrets appearing in chat history.	Post-quantum readiness for AI coding agents: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH), explain the harvest-now-decrypt-later exposure, get NIST ML-KEM/ML-DSA/SLH-DSA (and hybrid) migration guidance, verify fixes, and check dependencies. Content-based/advisory tools only. Run local (npx @quantakrypto/mcp) or the hosted OAuth endpoint at mcp.quantakrypto.com.
