List all versions of a tool
const url = 'https://example.com/v1/tools/example/versions?limit=25&includeTombstoned=false';const options = {method: 'GET', headers: {Authorization: 'Bearer <token>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}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 — dotted namespace (acme.lookup-order).
Query Parameters
Section titled “Query Parameters”1..100. Default 25.
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.
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
Section titled “Responses”Page of tool versions.

ToolId — dotted namespace (e.g. acme.verify-citation).
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.
JSON Schema (Draft 2020-12) for the tool input.

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.
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. Absent means false.
Isolation posture the runtime enforces around the handler. Optional additive field.
Sandbox-enforced resource caps at dispatch. Optional additive field.
object
Typed discriminated needs (env / secrets / config / capabilities / bindings). Optional additive field.

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.
object
URL template with {param} placeholders substituted from the tool’s input at invoke time.
object
Wall-clock timeout in ms. Default 30000.
When true (default), the response body is parsed as JSON before returning to the invoker.
object
ISO 8601 timestamp — present iff this version has been soft-tombstoned via POST /versions/:v/unregister. Absent on active versions.
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.
Opaque cursor for the next page. Absent when hasMore: false.
