WHAT IT DOES

What transit-engine-encryption-key-rotate does on Vault MCP Server (mschuchard)

AI agents invoke transit-engine-encryption-key-rotate to trigger actions in Vault MCP Server (mschuchard). What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why transit-engine-encryption-key-rotate needs a policy

Key rotation in Vault's Transit engine triggers a cryptographic operation that generates a new encryption key version and retires the old one for new encryption operations. This is an irreversible state change (old key version cannot be un-rotated) that affects all data encrypted under that key going forward.
