  • created_at: string

    A timestamp in RFC 3339 format

  • 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.

  • type: "memory_store"

    • "memory_store"

  • updated_at: string

    A timestamp in RFC 3339 format

  • archived_at: optional string

    A timestamp in RFC 3339 format

  • 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. Empty string when unset.

  • metadata: optional map[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.

• next_page: optional string

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