$client->beta->memoryStores->create(string name, ?string description, ?array<string,string> metadata, ?list<AnthropicBeta> betas, ?string workspaceID): BetaManagedAgentsMemoryStore
POST/v1/memory_stores

Create a memory store

Parameters
name: string

Human-readable name for the store. Required; 1–255 characters; no control characters. The mount-path slug under /mnt/memory/ is derived from this name (lowercased, non-alphanumeric runs collapsed to a hyphen). Names need not be unique within a workspace.

description?:optional 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.

metadata?:optional array<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. Not visible to the agent.

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 updatedAt

A timestamp in RFC 3339 format

?\Datetime archivedAt

A timestamp in RFC 3339 format

?string description

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.
