# 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
```
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:**
1. **HSM-only TDE**: HSM wallet OPEN (SINGLE), TDE_CONFIGURATION=HSM
2. **HSM with Auto-login (Migrated)**: HSM wallet OPEN (PRIMARY), auto-login wallet OPEN (SECONDARY), TDE_CONFIGURATION=HSM|FILE
3. **HSM with Auto-login (Not Migrated)**: HSM wallet OPEN (PRIMARY), auto-login wallet OPEN_NO_MASTER_KEY (SECONDARY), TDE_CONFIGURATION=HSM|FILE
4. **FILE wallet TDE**: PASSWORD wallet OPEN (SINGLE), TDE_CONFIGURATION=FILE
5. **FILE with Auto-login (Reverse Migrated)**: PASSWORD wallet OPEN (PRIMARY), auto-login wallet OPEN (SECONDARY), TDE_CONFIGURATION=FILE|HSM
6. **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)**
```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)**
```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**
```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**
```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`

**📚 References:**
- [Oracle V$ENCRYPTION_WALLET Documentation](https://docs.oracle.com/en/database/oracle/oracle-database/19/refrn/V-ENCRYPTION_WALLET.html)
- [Oracle TDE_CONFIGURATION Parameter](https://docs.oracle.com/en/database/oracle/oracle-database/19/refrn/TDE_CONFIGURATION.html)

### Example Prompts
```
"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
