Tools & capabilities

Aga MCP Server tools 15

  • get_server_infoGet AGA server info, public keys, and portal state.
  • get_portal_stateGet current portal state, loaded artifact info, and enforcement status.
  • init_chainInitialize continuity chain with genesis event.
  • attest_subjectAttest subject, generate sealed Policy Artifact. Auto-loads into portal.
  • measure_integrityMeasure subject state, compare to sealed reference. Generates signed receipt for every measurement.
  • revoke_artifactRevoke an active policy artifact mid-session. Portal terminates on next measurement. (NCCoE Phase 3b)
  • verify_chainVerify continuity chain integrity.
  • generate_evidence_bundleExport the canonical SEP evidence bundle: signed PERMITTED/DENIED tool-call receipts + Merkle proofs + a mandatory signed checkpoint, for offline third-party verification (verify_bundle_offline, aga-verify, or aga-receipt-spec/verify/verify-sep.mjs). Pin gateway_public_key to prove provenance.
  • verify_bundle_offlineVerify a canonical SEP evidence bundle offline (full §6 algorithm: structural floor, receipt signatures, chain+ordering, leaf-recompute + Merkle bijection, signed checkpoint). Pass pinned_public_key to also prove provenance.
  • request_claimRequest disclosure of a claim. Auto-substitutes if denied.
  • list_claimsList available claims with sensitivity levels.
  • delegate_to_subagentDerive a constrained policy artifact for a sub-agent. Scope can only diminish, never expand. (NCCoE constrained delegation)

Enigma Python MCP tools 1

  • encrypt_message Encrypt or decrypt a message using a specified Enigma machine configuration. 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.

Frequently asked questions

Aga MCP Server is categorized under Cryptography and uses a local stdio subprocess. Enigma Python MCP belongs to Cryptography and uses a local stdio subprocess. Pick Aga MCP Server for cryptography work and Enigma Python MCP for cryptography.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Aga MCP Server has no declared pricing — check the project's own site. Enigma Python MCP is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add aga-mcp-server and denismaggior8-enigma-python-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
