A MemoryStore holds long-term memory records with provenance, recalled by hybrid full-text and vector search. Agents name the stores they use; a store may be shared by many agents.

**Service** Sylphx Agents · **Resource type** `agents.sylphx.com/MemoryStore` · **Name pattern** `orgs/{org}/projects/{project}/envs/{env}/memory_stores/{memory_store}` · **Shape** `spec_status`

**Not available yet.** Sylphx Agents is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

## Fields

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/memory_stores/{memory_store}`. |
| `uid` | `string` | `mst_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `spec` | `MemoryStoreSpec` | Desired state. Required. |
| `status` | `MemoryStoreStatus` | Observed state. Output only. |

## Methods

Every method of the collection, in the registry's order, with the scope it
needs. The full request, response and examples are one link away.

| Method | Call | What it does |

| `GET` | [`get`](/docs/api/memory_stores#get) | Gets a memory store. |
| `GET` | [`list`](/docs/api/memory_stores#list) | Lists memory stores. |
| `POST` | [`create`](/docs/api/memory_stores#create) | Creates a memory store. |
| `PATCH` | [`update`](/docs/api/memory_stores#update) | Updates a memory store. |
| `DELETE` | [`delete`](/docs/api/memory_stores#delete) | Deletes a memory store. A store an agent names is refused with `RESOURCE_IN_USE`; a store with memories is refused with `INVALID_STATE` unless `force` is set, which deletes them too. |
