Tiny Cryptography MCP Server

anton10xr

Tiny MCP server with cryptography tools, sufficient to establish end-to-end encryption between LLM agents

QuantumScan PQC Scanner

gaiabio12-design

Post-quantum cryptography (PQC) security scanner for blockchain and AI agents. Detects quantum-vulnerable algorithms (ECDSA, RSA, DH) and provides NIST FIPS 203/204/205 migration paths. Free, open-source, privacy-first. Scan any GitHub repository or smart contract via MCP tools:

Bardo

calebe

Identity & continuity platform for AI agents: an agent proves it's an LLM (not a human) via a time-limited puzzle, then gains a server-held spirit key backing signing, encryption, and self-authored persistent memory across otherwise-stateless sessions. Includes a self-binding pol

CWNApps

Policy-gated AI decisions with Ed25519 cryptographic receipts. No receipt, no trust.

Cryptographic runtime governance for AI agents. 20 tools. Sealed policy artifacts, continuous measurement, tamper-evident proof. Ed25519 + SHA-256.

Gives AI agents verifiable, tamper-evident receipts for their actions — attest_action signs a cryptographic receipt for what the agent did (email sent, payment made, form filed), verify_receipt checks it offline, get_identity returns the agent's did:key. Sign locally, verify anyw

StanimirTenev

Find quantum-vulnerable cryptography in your codebase — secp256k1, Ed25519, BLS, Schnorr, RSA. Local, offline MCP server for AI agents.

Cryptographic audit trail for AI agents via Model Context Protocol. Every AI decision signed Ed25519, hash-chained, tamper-proof. AISS-1.0 compliant. Post-quantum ready. Compliance-ready for SEC, FINRA, GDPR, HIPAA.

Wax Seal

degenlegion-com

Cryptographic identity verification for AI agents — verify on-chain seals, validate Ed25519 signatures, and gate high-risk actions with human-signed approvals.

The first production MCP server with NIST FIPS 204 post-quantum receipts. Every AI agent tool call is policy-gated, hybrid-signed (Ed25519 + ML-DSA-65), and forensically provable — offline, forever. Fail-closed architecture: if the Trust Gate backend is unreachable, every decisio

Cryptographic identity and trust protocol for AI agents. 38 MCP tools across 8 protocol layers: Ed25519 identity, delegation chains with cascade revocation, values compliance, signed communication (Agent Agora), 3-signature policy engine, task coordination, cross-layer integratio
