Enigma Python MCP
Cryptography · Local stdio
Quality: 59/100 (Good) | Auth: No auth required
Verdict Summary: Choose Waxseal Sdk if you need specialized Cryptography tools running via a local process. Choose Enigma Python MCP if your workspace requires Cryptography integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Waxseal Sdk when:
You need dedicated capabilities in the Cryptography domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (Free / Open Source).
You have access to required keys: WAXSEAL_PRIVATE_KEY_PEM.
Primary tools included: Verify on-chain identities by fingerprint, Validate Ed25519 document signatures, Check human approval tokens.
On-chain Ed25519 identity for AI agents — verify seals by fingerprint, validate document signatures, and gate irreversible actions behind human-signed approval tokens. Hosted at api.waxseal.id/mcp; local install (npx @waxseal/mcp) for signing.
A Model Context Protocol server that brings the capabilities of enigmapython library to LLMs, allowing them to encrypt and decrypt messages using historically accurate Enigma machine emulators.

Args:
machine_model: Exact machine model name. MUST be one of: 'M3', 'M4', 'I', 'I_Norway', 'I_Sondermaschine', 'K', 'K_Swiss', 'D', 'Z', 'B_A133', 'T'. Do not add 'Enigma' prefix.
Supported models and their explicitly required reflectors:
- 'M3', 'I': UKWA, UKWB, UKWC
- 'M4': UKWBThin, UKWCThin
- 'I_Norway': UKW_EnigmaINorway
- 'I_Sondermaschine': UKW_EnigmaISonder
- 'K', 'K_Swiss', 'D': UKW_EnigmaCommercial
- 'Z': UKW_EnigmaZ
- 'B_A133': UKW_EnigmaB_A133
- 'T': UKW_EnigmaT
message: The plaintext or ciphertext to process.
- For Enigma Z: MUST contain ONLY digits (1234567890).
- For Enigma B_A133: MUST contain ONLY Swedish letters (abcdefghijklmnopqrstuvxyzåäö). Note: 'w' is strictly forbidden.
- For all other machines: MUST contain ONLY standard letters (A-Z).
- Spaces, punctuation, and special characters are strictly forbidden in all machines.
rotors: List of RotorConfig objects. MUST be ordered exactly as: [Fastest/Rightmost, Middle, Slowest/Leftmost, Greek (if M4)].
reflector: The ReflectorConfig object.
plugboard_pairs: Optional dict for plugboard connections (e.g. {"A": "B", "C": "D"}). Ignored if the machine has no plugboard.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Waxseal Sdk is categorized under Cryptography and uses a local stdio subprocess. In contrast, Enigma Python MCP belongs to Cryptography using local stdio subprocess. Select Waxseal Sdk when you need capabilities focused on cryptography and Enigma Python MCP when you require tools for cryptography.
