Address	`https://api.hanzo.ai/v1/sandbox`
Method	`GET`
Operation	`get_sandbox`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Lists the sandboxes the caller holds, newest first.

A member holds the sandboxes they leased; an admin of the org, or a SuperAdmin, holds every one in it. ?project= and ?status= narrow it. Only the caller's org's: the store is keyed on the validated org, so another tenant's sandbox is not something this operation can return.

200 body — 17 fields.

Field	In	Type	Always	Description
`sandboxes`	body	sandbox.Sandbox[]	—	Sandboxes are the sandboxes the caller holds that match the filter: the ones they leased, or every one in the org for an admin of it.
`sandboxes[].actor`	body	string	—	Actor is the subject who LEASED this sandbox — the validated caller of the act that took the lease, never a value a request supplied.
`sandboxes[].class`	body	string	—	Class is what the sandbox is FOR, and it decides the image, the working directory and the isolation: "exec" for a code-interpreter call (workdir /mnt/data, no project, bounded per org), "dev" for a workspace bound to a project (workdir /work, single-attach), "desktop" for one with a screen.
`sandboxes[].cluster`	body	string	—	Cluster is the attached cluster this sandbox runs on — the fleet-local name the lease named — or empty for the home cluster.
`sandboxes[].connectedAt`	body	integer (int64)	—	ConnectedAt is when somebody was last known to have this sandbox's project OPEN, Unix seconds.
`sandboxes[].createdAt`	body	integer (int64)	—	CreatedAt is when the lease was taken, Unix seconds — by the lease that made the sandbox, and again by each resume, which gives a parked sandbox a new pod on a new lease.
`sandboxes[].error`	body	string	—	Error is why the sandbox could not come up, in plain words.
`sandboxes[].expiresAt`	body	integer (int64)	—	ExpiresAt is when the lease ends, Unix seconds.
`sandboxes[].id`	body	string	—	ID is the sandbox's server-minted handle and what every operation addresses it by.
`sandboxes[].image`	body	string	—	Image is the container image this sandbox is actually running — the one the class chose, or an override the policy admitted.
`sandboxes[].kind`	body	string	—	Kind is the resource family this row belongs to.
`sandboxes[].lastUsedAt`	body	integer (int64)	—	LastUsedAt is when the sandbox last did work, Unix seconds.
`sandboxes[].org`	body	string	—	Org is the org that holds the lease — the validated caller's, never a value a request supplied.
`sandboxes[].project`	body	string	—	Project is the project this sandbox is bound to.
`sandboxes[].runtime`	body	string	—	Runtime is the isolation boundary this sandbox GOT, which is not always the one it asked for: a caller states a preference and runtimeFor answers with what the sandbox can actually have.
`sandboxes[].status`	body	string	—	Status is where the sandbox is in its life: "pending" while the pod is coming up, "running" once it can take work, "error" when it cannot, and "parked" when its pod is stopped and its disk kept, until a resume.
`sandboxes[].volume`	body	string	—	Volume is the persistent volume attached to the sandbox, when it has one.

Failure carries the platform error shape — see Errors.

MCP reaches sandbox through the sandbox tool, which names its 17 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_sandboxes"
         }
       }
     }'
