Cipher FAQs

Question 1

How does Cipher MCP enhance AI agent workflows?

Accepted Answer

Cipher MCP centralizes all necessary cipher operations, from preparing plaintext and validating keys to performing the actual cipher operations and exploring unknown ciphertexts, making cryptographic tasks seamless for AI agents.

Question 2

How many classical ciphers does Cipher MCP support?

Accepted Answer

Cipher MCP supports encryption and decryption for all 72 classical ciphers available through the upstream cipher.tools API. It also offers enhanced local support for popular ciphers like Caesar, Affine, and Vigenere.

Question 3

What is Cipher MCP?

Accepted Answer

Cipher MCP is an MCP server built specifically for classical cipher workflows, allowing AI agents to easily encrypt, decrypt, normalize, validate, and explore a wide range of classical ciphers.

Question 4

Is Cipher MCP suitable for sensitive data?

Accepted Answer

While local helper tools run offline, encryption and decryption operations (`encrypt_text`, `decrypt_text`) call the public `cipher.tools` API over the network. For sensitive material, these should be treated as remote API calls.

Question 5

What features does Cipher MCP offer?

Accepted Answer

It provides encryption and decryption for 72 classical ciphers, text normalization, input validation, random key generation, cipher examples, and heuristic detection of possible cipher families from text shape.
