Mcp Cryptography

Gives Claude direct access to Python's cryptography library through a comprehensive set of tools. You get symmetric encryption with Fernet and AES, asymmetric operations with RSA and X25519, standard hashing functions like SHA-256 and SHA-512, HMAC signing and verification, and key derivation through PBKDF2 and Scrypt. It also handles X.509 certificate generation and parsing, plus utilities for generating random bytes. Reach for this when you need Claude to perform cryptographic operations during a conversation without writing custom code, whether that's encrypting sensitive data, generating keys, signing messages, or working with certificates. All operations run locally through stdio transport.
