Thales CipherTrust Data Security Platform CAKM MCP Server

A Model Context Protocol (MCP) server for Database EKM/TDE operations using CipherTrust Application Key Management (CAKM).

🔑 Features

Resource-Based Management: Tools are organized by the database objects they manage (e.g., keys, encryption, wallets), not just by actions.
Operational Grouping: Each tool exposes multiple operations (e.g., create, list, rotate) for comprehensive lifecycle management.
Unified Status & Auditing: A single tool (status_tde_ekm) provides health, compliance, and configuration monitoring across all supported databases.
Advanced Oracle TDE Detection: Intelligent detection of Oracle TDE configurations including:
- HSM-only TDE: Direct HSM wallet usage
- HSM with Auto-login: Forward migrated configurations (HSM primary, auto-login secondary)
- FILE wallet TDE: Password-based software wallets
- FILE with Auto-login: Standard or reverse migrated configurations
- Migration Status Recognition: Automatically identifies forward/reverse migration states based on wallet order and types
Database TDE Operations: Encrypt, decrypt, and manage TDE on multiple database types.
CipherTrust Integration: Seamless integration with CipherTrust Manager via CAKM EKM.
Multi-Database Support: SQL Server and Oracle Database.
Key Rotation: Automated encryption key rotation with key management on Thales CipherTrust Manager.

Architecture Overview

hljs language-arduino

MCP Server ↔ Database Server ↔ CAKM Provider/Library ↔ CipherTrust Manager

Note: This MCP server communicates only with database servers. The CAKM providers installed on database servers handle all communication with CipherTrust Manager.

Oracle TDE Enablement Logic

The server uses Oracle-documented logic to determine TDE status based on wallet configurations and TDE parameters:

✅ TDE is ENABLED when:

Any wallet shows OPEN status AND Master Encryption Keys (MEKs) exist

📊 Wallet Order Types (from Oracle V$ENCRYPTION_WALLET):

SINGLE: Only one wallet type configured
PRIMARY: Primary wallet in a dual-wallet configuration
SECONDARY: Secondary wallet in a dual-wallet configuration

🔧 TDE Configuration Parameter Values:

FILE: TDE configured to use FILE wallets only
HSM: TDE configured to use HSM wallets only
HSM|FILE: TDE configured with HSM as primary, FILE as secondary
FILE|HSM: TDE configured with FILE as primary, HSM as secondary

📊 Supported TDE Scenarios:

HSM-only TDE: HSM wallet OPEN (SINGLE), TDE_CONFIGURATION=HSM
HSM with Auto-login (Migrated): HSM wallet OPEN (PRIMARY), auto-login wallet OPEN (SECONDARY), TDE_CONFIGURATION=HSM|FILE
HSM with Auto-login (Not Migrated): HSM wallet OPEN (PRIMARY), auto-login wallet OPEN_NO_MASTER_KEY (SECONDARY), TDE_CONFIGURATION=HSM|FILE
FILE wallet TDE: PASSWORD wallet OPEN (SINGLE), TDE_CONFIGURATION=FILE
FILE with Auto-login (Reverse Migrated): PASSWORD wallet OPEN (PRIMARY), auto-login wallet OPEN (SECONDARY), TDE_CONFIGURATION=FILE|HSM
FILE with Auto-login: PASSWORD wallet OPEN (PRIMARY), auto-login wallet OPEN (SECONDARY), TDE_CONFIGURATION=FILE

🔍 Migration Detection Logic:

Forward Migration: HSM becomes PRIMARY (HSM|FILE configuration) → Database migrated from FILE to HSM
Reverse Migration: FILE becomes PRIMARY (FILE|HSM configuration) → Database migrated from HSM back to FILE
WALLET_ORDER and TDE_CONFIGURATION are correlated to determine the migration state

📋 Status Information:

TDE configuration parameters validate the expected wallet hierarchy
Wallet order and TDE_CONFIGURATION together determine the deployment scenario

🔧 Oracle TDE Operations Guide

The oracle_tde_deployment tool provides different operations for various TDE setup scenarios:

Operation Types & Use Cases

1. HSM-Only TDE Setup (No Auto-login)

hljs language-json

{
  "oracle_connection": "oracle_cdb2",
  "operation": "setup_hsm_only",
  "ciphertrust_username": "tdeuser",
  "ciphertrust_password": "Thales123!",
  "ciphertrust_domain": "TDE",
  "auto_restart": true
}

Use when: "Skip auto-login wallet creation" or "HSM only"
Creates: HSM keystore only
Result: Manual wallet opening required after restarts
No software_wallet_password needed

2. Complete TDE Setup (HSM + Auto-login)

hljs language-json

{
  "oracle_connection": "oracle_cdb2",
  "operation": "setup_hsm_with_autologin",
  "ciphertrust_username": "tdeuser", 
  "ciphertrust_password": "Thales123!",
  "ciphertrust_domain": "TDE",
  "software_wallet_password": "Thales123!",
  "auto_restart": true
}

Use when: "Set up complete TDE with auto-login"
Creates: HSM + software wallet + auto-login keystore
Result: Database starts automatically without manual intervention
Requires software_wallet_password

3. Add Auto-login to Existing TDE

hljs language-json

{
  "oracle_connection": "oracle_cdb2",
  "operation": "add_autologin",
  "ciphertrust_username": "tdeuser",
  "ciphertrust_password": "Thales123!", 
  "ciphertrust_domain": "TDE",
  "software_wallet_password": "Thales123!",
  "auto_restart": true
}

Use when: Database has HSM TDE, want to add auto-login
Creates: Software wallet + auto-login for existing HSM setup
Requires software_wallet_password

4. Check TDE Status

hljs language-json

{
  "oracle_connection": "oracle_cdb2",
  "operation": "get_tde_status"
}

Use when: Want to see current TDE configuration
Returns: Comprehensive wallet and TDE status
No credentials needed

Quick Reference

"Skip auto-login" → Use setup_hsm_only
"Complete TDE setup" → Use setup_hsm_with_autologin
"Add auto-login to existing" → Use add_autologin
"Check what I have" → Use get_tde_status

Example Prompts

hljs language-arduino

"Show me the TDE status of all my databases"
"For my 'prod_sql' connection, list all the asymmetric keys using the 'manage_sql_keys' tool"
"Rotate the master key on the 'Db05' database using the 'prod_sql' connection"
"Encrypt the 'SalesDB' database on my 'prod_sql' server"
"What is the wallet status for my 'oracle_cdb2' connection?"

Important Notes

Automatic Database Restarts: When specified in prompts, MCP tools can automatically restart Oracle databases as part of TDE operations
SSH Authentication: Oracle connections support both private key and password authentication
- Private key: Use "private_key_path": "/path/to/key.pem" in ssh_config
- Password: Use "password": "your_ssh_password" in ssh_config (instead of private_key_path)
Supported Databases: Microsoft SQL Server and Oracle Database are supported
