"crypto" matching MCP servers:

Enables cryptographic operations including hashing, encoding/decoding, ID generation, password tools, and JWT inspection via MCP.

Defense-grade cryptographic compliance and analysis tools for MCP, including FIPS 140-3 validation, CNSA 2.0 analysis, post-quantum readiness assessment, and classical cipher utilities.

Generates strong passwords and evaluates password strength using zxcvbn, with uniform random sampling via Node's crypto.

MCP server for on-chain attestation and wallet trust profiles across 31 EVM chains and Solana. Privacy-preserving boolean verification, ECDSA-signed responses, compliance templates.

Exposes various cryptographic operations including key generation, symmetric/asymmetric encryption, hashing, and HMAC. Supports Fernet, AES, RSA, X.25519, and X.509 certificates.

19 tools for crypto token risk intelligence. Detect rug pulls, honeypots, and scams before your agent transacts. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Provides blockchain address risk scoring and asset information through the BICScan API, allowing users to assess risks for crypto addresses, domains, and dApps on a scale of 0-100.

A Model Context Protocol server for AES encryption and decryption, supporting various modes, padding, and input/output formats for secure data handling.

Exposes common CTF and cybersecurity tools (crypto, forensics, malware analysis, steganography, reverse engineering, pwn, OSINT) so LLMs can help solve capture-the-flag challenges in a controlled lab environment.

Intent-based permission system with risk scoring, rule engine, and audit trail for AI agents.

Enables AI assistants to perform quantum-resistant cryptographic operations using NIST-standardized algorithms including ML-KEM, ML-DSA, and SPHINCS+. Supports key generation, encryption, digital signatures, and security analysis for post-quantum cryptography research and development.

Encrypted-at-rest credential vault with MCP server for agent credential lookup and management.

Zero-dependency Web Crypto suite & Model Context Protocol (MCP) server for AES-256-GCM, RSA-4096, and AI agent security.

Enables AI agents to perform symmetric and asymmetric encryption of text and files using secure storage in the macOS Keychain. It provides tools for identity management and secure messaging compatible with the CryptoSeed iOS app and CLI.

A Model Context Protocol server built with Express.js that provides cryptographic tools including key pair generation, shared secret derivation, and message encryption/decryption.

The deterministic fact-verification layer for AI agents. Validates the structured facts an agent emits — IBANs, payment cards, VAT and national tax IDs, crypto and bank addresses, domains, emails, phone numbers, securities and academic identifiers, plus dates, currencies and holidays — against checksums and curated authoritative data, not guesses.
