MongoDB

Overview#

The MongoDB connector seals Atlas or self-hosted MongoDB connection strings in QuantaVault. Proxy operations support find, insertOne, updateOne, deleteOne, and aggregate. Field-level tokenization can be applied to PII document fields before insert.

Prerequisites#

• 1MongoDB Atlas cluster or self-hosted MongoDB 5.0+
• 2A database user with the required collection roles
• 3MongoDB connection string (SRV or standard format)
• 4A QuantaSeal API key

Configuration#

Follow these steps to connect MongoDB to QuantaSeal. You can configure integrations via the Admin Console or directly via the API.

1. 1

   In Atlas, create a database user with the readWrite role on the target database.

2. 2

   Seal the connection string: POST /api/v2/vault/seal with credential_type: database_dsn.

3. 3

   Create the integration: POST /api/v2/integrations with system_type: mongodb.

Authentication Types#

Store the full MongoDB connection string as database_dsn: mongodb+srv://user:pass@cluster.mongodb.net/mydb?retryWrites=true

All credential types are sealed in QuantaVault with ML-KEM-768 + AES-256-GCM and wrapped by your tenant AWS KMS CMK before storage. See the Vault API reference for the full list of credential types and seal/unseal endpoints.

Available Operations#

QuantaSeal enforces a default-deny operation policy. Only operations listed in your integration's allowed_operations array will be permitted. Add operations when creating or updating the integration.

Code Example#

Every proxy call returns a HybridCryptoEnvelope - the response is ML-KEM-768 key-encapsulated, AES-256-GCM encrypted, and signed with ML-DSA-65 + HMAC-SHA-512. Verify both signatures before trusting the decrypted payload.

curl -X POST https://api.quantaseal.io/api/v2/proxy/outbound \
  -H "X-API-Key: qs_live_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{
