Bridges Claude to IBM Z mainframes through two distinct paths: Key Protect for HSM-backed encryption (FIPS 140-2 Level 3) and z/OS Connect for calling CICS, IMS, and batch programs via REST. On the crypto side, you get envelope encryption workflows like wrapping DEKs with root keys that never leave the hardware, plus rotation and policy management. On the mainframe side, it translates JSON to COBOL copybooks so you can invoke legacy programs without touching JCL. Useful when you need Claude to orchestrate key lifecycles in regulated environments or interact with core banking and transaction systems that still run on Big Iron. Requires IBM Cloud credentials for Key Protect and mainframe auth for z/OS Connect.
