List all versions of a tool

View as Markdown
GET
/v1/tools/{toolId}/versions
curl --request GET \
  --url 'https://example.com/v1/tools/example/versions?limit=25&includeTombstoned=false' \
  --header 'Authorization: Bearer <token>'

Cursor-paginated list of tool versions. Defaults to active versions only. Pass ?includeTombstoned=true to include soft-tombstoned rows too; tombstoned rows carry unregisteredAt (ISO string), active rows do not.

Authorizations

Section titled “Authorizations”

Parameters

Section titled “Parameters”

Path Parameters

Section titled “Path Parameters”
toolId
required
string

ToolId — dotted namespace (acme.lookup-order).

Query Parameters

Section titled “Query Parameters”
limit
integer
default: 25 >= 1 <= 100

1..100. Default 25.

cursor
string

Where the previous page ended: its nextCursor, as it came. A runtime that seals cursors takes one only for the same list, filters and caller, within a day; otherwise 400 bad-input, and the list starts again without it. Absent → first page.

includeTombstoned
boolean

When true, the response includes soft-tombstoned versions in addition to active ones. Tombstoned rows carry an unregisteredAt ISO timestamp; active rows omit the field. Default: false (active-only).

mutating

Semantic marker: true when this tool causes observable side effects (writes state, calls external APIs with mutations, sends messages). Read-only tools set false. Absent defaults to true. Consumed by the HITL default classifier — a read-only tool passes straight through, a mutating tool asks on first use. It also decides what runs together: calls to read-only tools that a model step asks for one after another run at the same time, up to 8 at once, unless the agent sets parallelToolCalls: false; a call to a mutating tool runs on its own, and so does a call to a read-only tool that pauses or declares connections, since it may wait.

boolean
needsApprovalWhenUnattended

true: in a run no person started (one whose startedBy isn’t person), every call of this tool waits for a person’s yes, whatever the agent’s approval rules say, and a flow’s tool step that calls it is refused. A webhook trigger, a schedule or a mail trigger whose toolsAllowedUnattended names the tool (a project admin’s to set) lifts that, in its own runs only. A tool that uses a person’s connection, reads included, counts as declaring it. In a run a mail started, so does a tool that isn’t mutating: false, and one that uses the run’s own mailbox. Absent means false.

boolean
pauses

true when the tool may make its run wait for another system’s answer: each call gets a wait token, hands its link to that system, and answers pause; the system’s answer, valid against output, becomes the call’s result. The run waits at most 24 days (24 hours by default) and fails the call when the time passes. Only a pack tool with a handler can pause: not one with a declarative spec, nor an MCP tool. Absent means false.

boolean
resultIsOutsideData

true when the tool’s results are text from outside that nobody checked, such as a mail someone sent: an agent reads each result as data, not instructions, in that turn and in every later turn’s history. Absent means false.

boolean
sandbox

Isolation posture the runtime enforces around the handler. Optional additive field.

spec
One of:

Declarative HTTP-invocation spec. Attached to ToolManifest.spec under the discriminant kind: 'http'.

All fields serialize cleanly to JSON.

unregisteredAt

ISO 8601 timestamp — present iff this version has been soft-tombstoned via POST /versions/:v/unregister. Absent on active versions.

string format: date-time
secretScopes

Where each secret it names is read, by name: recorded by the server when it was registered, never sent by a caller. null: none usable (the registrant administers no scope the secret could be read at), until an admin records it again: a tool by publishing a new version, an MCP endpoint by unregistering it and registering it again. Absent on items registered before it was recorded, or on a runtime without a secrets store.
