List memories

Path parameters
memory_store_id: string
Query parameters
depth: optional number

0 (or omitted) returns all descendants below path_prefix (recursive). 1 returns immediate children only; deeper entries roll up as memory_prefix items. depth=1 behaves like ls; omitting depth behaves like find.

formatint32
limit: optional number

Maximum number of items to return per page. Must be between 1 and 100. Defaults to 20 when omitted. Capped at 20 when view=full. Both memory and memory_prefix items count toward the limit.

formatint32
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.

path_prefix: optional string

Optional path prefix filter. Must end with / (segment-aligned), e.g., /notes/. This value appears in request URLs. Do not include secrets or personally identifiable information.

view: optional BetaManagedAgentsMemoryView

Which projection of each memory to return. Defaults to basic (content omitted). full populates content on each item and caps limit at 20; use this as the bulk-read path for export and sync.

One of the following:
"basic"
"full"
Headers
"anthropic-beta": optional array of AnthropicBeta

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

One of the following:

Returns
data: optional array of BetaManagedAgentsMemoryListItem

One page of results. Each item is either a memory object or, when depth was set, a memory_prefix rollup marker. Items are returned in a stable, server-defined order.

One of the following:
BetaManagedAgentsMemory object{ id, content_sha256, content_size_bytes, 7 more }

A memory object: a single text document at a hierarchical path inside a memory store. The content field is populated when view=full and null when view=basic; the content_size_bytes and content_sha256 fields are always populated so sync clients can diff without fetching content. Memories are addressed by their mem_... ID; the path is the create key and can be changed via update.

BetaManagedAgentsMemoryPrefix object{ path, type }

A rolled-up directory marker returned by List memories when depth is set. Indicates that one or more memories exist deeper than the requested depth under this prefix. This is a list-time rollup, not a stored resource; it has no ID and no lifecycle. Each prefix counts toward the page limit and interleaves with memory items in path order.

path: string

The rolled-up path prefix, including a trailing / (e.g. /projects/foo/). Pass this value as path_prefix on a subsequent list call to drill into the directory.

type: "memory_prefix"
next_page: optional string or null

Opaque cursor for the next page (a page_... value), or null if there are no more results. Pass as page on the next request.
