# list_topic_categories

> List the category channels available for filtering

The categories usable as `category_id` on [`list_topics`](/mcp/tools/list-topics).
Category channels only — the home navigation's sort channels (Latest,
Following, …) are rankings, not filterable content, and are not returned here.

**Scope**: `read` · **Annotations**: `readOnlyHint`
**REST equivalent**: `GET /open/v1/topic-categories`

## Parameters

| Name       | Type                                     | Required | Default | Notes                                |
| ---------- | ---------------------------------------- | -------- | ------- | ------------------------------------ |
| `language` | see [languages](/mcp/overview#languages) |          | `en`    | Names and descriptions are localized |

## Returns

Not paginated — `next_cursor` is always `null`. Captured live:
