# List all versions of a tool

GET

/v1/tools/{toolId}/versions

```sh
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

- **[bearerAuth](https://docs.kindgi.com/v0.1.8/reference/api.md#bearerauth)**

## Parameters

### Path Parameters

**toolId**

required

string

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

### 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).

## Responses

### 200

Page of tool versions.

**id**

required

ToolId — dotted namespace (e.g. `acme.verify-citation`).

string

\>= 1 characters

**projectId**

The tool’s project: every version of a tool is in the one project. Absent when the runtime doesn’t record it: a pack `kindgi dev` serves from disk, or a runtime before Kindgi 0.1.6.

**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.

boolean

**sandbox**

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

**spec**

One of:

- **object**

  Declarative HTTP-invocation spec. Attached to `ToolManifest.spec` under the discriminant `kind: 'http'`. The runtime `Tool.handler` is synthesized by the ‘http’ spec synthesizer to perform URL-template substitution, secret-ref resolution via `ToolContext.resolveSecret`, and the outbound fetch. All fields serialize cleanly to JSON.

  **max**

  required

  integer

  \>= 100 <= 599

**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.
