workspace_id?: string

Header param: Optional header to select the Workspace for this request. The value is a Workspace ID (for example, wrkspc_011CZkZaBF1tNoB5wlCeusgy).

Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

Returns
interface BetaManagedAgentsMemoryStore { type: "memory_store"; id; archived_at; /* 5 more */ }

A memory_store: a named container for agent memories, scoped to a workspace. Attach a store to a session via resources[] to mount it as a directory the agent can read and write.

type: "memory_store"
id: string

Unique identifier for the memory store (a memstore_... tagged ID). Use this when attaching the store to a session, or in the {memory_store_id} path parameter of subsequent calls.

archived_at: string | null

Timestamp when the store was archived, or null if active. Set once and never cleared; archiving is one-way. Archived stores are read-only and cannot be attached to new sessions.

formatdate-time
created_at: string

Timestamp when the store was created.

formatdate-time
description: string

Free-text description of what the store contains, up to 1024 characters. Included in the agent's system prompt when the store is attached, so word it to be useful to the agent. Empty string when unset.

metadata: Record<string, string>

Arbitrary key-value tags for your own bookkeeping (such as the end user a store belongs to). Up to 16 pairs; keys 1–64 characters; values up to 512 characters. Returned on retrieve/list but not filterable.

name: string

Human-readable name for the store. 1–255 characters. The store's mount-path slug under /mnt/memory/ is derived from this name.

updated_at: string

Timestamp when the store's name, description, or metadata was last modified. Memory writes inside the store do not advance this.

formatdate-time
