Parameters
createdAtGte?:optional \Datetime

Return only stores whose created_at is at or after this time (inclusive). Sent on the wire as created_at[gte].

createdAtLte?:optional \Datetime

Return only stores whose created_at is at or before this time (inclusive). Sent on the wire as created_at[lte].

includeArchived?:optional bool

limit?:optional int

Maximum number of stores to return per page. Must be between 1 and 100. Defaults to 20 when omitted.

page?:optional string

Opaque pagination cursor (a page_... value). Pass the next_page value from a previous response to fetch the next page; omit for the first page.

betas?:optional list<AnthropicBeta>

Optional header to specify the beta version(s) you want to use.

workspaceID?:optional string
Returns
class BetaManagedAgentsMemoryStore { $type; $id; $createdAt; /* 5 more */ }
Type type
string id

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.

\Datetime createdAt

A timestamp in RFC 3339 format

string name

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

?\Datetime archivedAt

A timestamp in RFC 3339 format

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.

?array<string,string> metadata

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.
