Initial PoC: find_protection, tagged checkpoints, FLR, mutating catalog. Lab 10.9 status enums (0=Initializing, 1=MeetingSLA). Credentials stay in gitignored config.json.

Zerto AI Rewind
PoC MCP that teaches an agent to discover Zerto protection, pin a tagged checkpoint before changing a VM, and recover a file from that tag. If the loop works, these tools are the delta to put in official ZVM MCP.
Language
Tagged checkpoint:
A named bookmark in a VPG journal, inserted by POST /v1/vpgs/{id}/checkpoints. Crash-consistent write-order only; not application-quiesced unless someone scripted that separately.
Avoid: user checkpoint, snapshot, backup, restore point (unqualified)
VPG: A Virtual Protection Group. One to many VMs sharing a journal. A VM can belong to at most three VPGs, recovered to different sites. Avoid: job, policy, replication group
Rewind: The agent loop: find protection, tag every protecting VPG, mutate, then bounded recover. Not a Zerto product name. Avoid: failover (that's DR), undo (that's git or Moholo)
Bounded recover: FLR, offsite clone, or failover test. Failover Live is not a rewind tool. Avoid: recover (unqualified), fail back, restore the VPG
File-level recovery (FLR): Mount a VM from a journal checkpoint and pull files. The VM stays up. 10.9 FLR Operator RBAC is broken; Administrator is the documented workaround. Avoid: file restore (unqualified), instant restore (local-journal VMs only, not v1)
find_protection: Resolve a VM name, hostname, or Zerto vmIdentifier to exactly one VM and every VPG it is in. Zero or two-plus VMs is a hard stop. Avoid: GetVms (that's the raw inventory call)
Protecting VPG: A VPG whose status is MeetingSLA or a NotMeetingSLA variant, and whose substatus is not a sync. Only these get tagged. 10.9 status 0 is Initializing, not Protecting. A resync deletes existing checkpoints. Avoid: healthy, in sync, Protecting (as status 0)
Mutating catalog:
The opt-in list of MCP tools that must call zerto_guard_before_mutate first. Unlisted tools pass through. Users add entries; the starter list is not the whole world.
Avoid: denylist, hold-everything
Official ZVM MCP:
HPE Zerto 10.9 MCP (ZVM.MCP): inventory, VPG settings, failover test. Not in the demo path. This PoC is one server.
Avoid: Zerto MCP (unqualified when you mean this repo)
