Mcp Hashlib
Gives Claude direct access to Python's hashlib for cryptographic operations. You get all the standard hashing algorithms like MD5, SHA family (including SHA3), BLAKE2, and SHAKE, plus key derivation functions like PBKDF2-HMAC and scrypt. The server exposes 22 tools covering everything from basic string hashing to incremental updates, file digests, and algorithm introspection. Reach for this when you need Claude to compute checksums, verify file integrity, or handle password hashing workflows without writing custom tooling. It's a straightforward wrapper over hashlib with stdio transport, so integration is simple.
