+## Media Server Settings (via API)

+Configured through CRUD at `/api/v1/media-servers`:
+
+| Setting | Description |
+|---------|-------------|
+| `name` | Display name for the server |
+| `type` | `plex` or `jellyfin` |
+| `url` | Server base URL (e.g., `http://192.168.1.100:32400`) |
+| `token` | Authentication token (redacted in API responses) |
+| `librarySection` | Library section ID for targeted scans (Plex section ID or Jellyfin library ID) |
+| `enabled` | Enable/disable auto-scan triggers |
+
+Action endpoints:
+- `POST /api/v1/media-servers/:id/test` — Test connection to the media server
+- `GET /api/v1/media-servers/:id/sections` — List available library sections (Plex only)
+
+## Keyword Filters (via API)
+
+Configured per-channel through `PUT /api/v1/channel/:id`:
+
+| Field | Description |
+|-------|-------------|
+| `includeKeywords` | Pipe-separated patterns — only matching titles are kept |
+| `excludeKeywords` | Pipe-separated patterns — matching titles are filtered out |
+
+Three pattern types are supported:
+- **Plain text** — case-insensitive substring match (e.g., `shorts`)
+- **Glob** — `*` wildcards, anchored to full title (e.g., `*tutorial*`)
+- **Regex** — `/pattern/` syntax, always case-insensitive (e.g., `/shorts|#shorts/`)
+
+Filters are applied during scheduled scans after dedup but before DB insertion.
