  }
}

Environment Variables

Variable	Description	Required
`IBM_CLOUD_API_KEY`	IBM Cloud API key	Yes (Key Protect)
`KEY_PROTECT_INSTANCE_ID`	Key Protect instance OCID	Yes (Key Protect)
`KEY_PROTECT_URL`	Key Protect endpoint	No (defaults to us-south)

Key Concepts

Envelope Encryption

Root keys (KEK) are stored in the HSM and never leave the hardware. Data encryption keys (DEK) are wrapped by root keys for safe storage alongside ciphertext.

z/OS Connect

REST APIs that automatically map JSON payloads to COBOL copybooks, enabling access to CICS transactions, IMS programs, and batch jobs.

Dependencies

@modelcontextprotocol/sdk -- MCP protocol SDK
@ibm-cloud/ibm-key-protect -- Key Protect client
