The hosted VideoDB MCP server at `https://mcp.videodb.io/mcp` exposes 89 tools, grouped into toolsets by what they operate on. Every tool is annotated with a kind, which is how a client knows whether the call changes your account and whether to ask you first. | Kind | Meaning | | - | - | | read | No change to your account. Lists, lookups, search and ask. | | create | Makes something new: assets, indexes, streams, jobs. | | update | Changes something that exists: renames, status toggles, visibility. | | destructive | Deletes. | ## IDs and conventions | Prefix | Object | | - | - | | `m-` | Video | | `a-` | Audio | | `img-` | Image | | `rts-` | Real-time stream | | `c-` | Collection | Every ID input takes one of those prefixed forms: `video_id` is an `m-` ID, `audio_id` an `a-` ID, `image_id` an `img-` ID, `rtstream_id` an `rts-` ID, `collection_id` a `c-` ID. `media_id` accepts a video or an audio ID. Every account has a collection named `default`, so leaving `collection_id` out sends the call there. Reading the Inputs column: a plain name is required, a trailing `?` means optional, and `?=value` is the default the server applies when you omit it. Tools with more than eight inputs show the first six, and a full table of every field follows the toolset table. * Inputs and outputs are snake\_case. * A write that runs long returns `{"status": "processing", ...}` with a `retry_with` field naming the read tool that shows the finished result. * Large lists are capped. A capped result carries `truncated: true` and `total`. ## collections Collections hold your media. Account usage and invoices live here too. | Tool | Kind | Inputs | What it does | | - | - | - | - | | `list_collections` | read | none | List all collections in the account with IDs, names, descriptions and visibility. | | `get_collection` | read | `collection_id?=default` | Get one collection's ID, name, description and public/private visibility. | | `create_collection` | create | `name`, `description?=""`, `is_public?=false` | Create a new collection to organize videos. | | `update_collection` | update | `collection_id?=default`, `name?`, `description?`, `is_public?` | Rename a collection, change its description, or switch it between public and private. | | `delete_collection` | destructive | `collection_id` | Permanently delete a collection and everything in it. | | `get_account_usage` | read | none | Get the account's current usage and billing summary. | | `list_invoices` | read | none | List the account's invoices (first 200; `truncated` is set when more exist). | ## media List, fetch, upload, rename and delete videos, audio and images, plus thumbnails, signed download URLs and transcoding. | Tool | Kind | Inputs | What it does | | - | - | - | - | | `list_assets` | read | `collection_id?`, `asset_type?`, `name_pattern?`, `min_duration?`, `max_duration?`, `min_size?`, +5 more (see below) | List videos, audio and images together in one paginated result, filtered by type, name pattern, duration or file size, and sorted by name, duration or size. | | `list_videos` | read | `collection_id?=default` | List videos in a collection: IDs, names, durations, and playable stream/player URLs. | | `list_audios` | read | `collection_id?=default` | List audio files in a collection: IDs, names, durations and sizes. | | `list_images` | read | `collection_id?=default` | List images in a collection: IDs, names and URLs. | | `get_video` | read | `video_id`, `collection_id?=default` | Get metadata for one video: name, duration, thumbnail, stream URL, and a player URL for watching it in a browser. | | `get_audio` | read | `audio_id`, `collection_id?=default` | Get metadata for one audio file: name, duration and size. | | `get_image` | read | `image_id`, `collection_id?=default` | Get metadata for one image: name and URL. | | `upload_media` | create | `url`, `collection_id?=default`, `name?`, `description?`, `media_type?`, `callback_url?` | Upload a video, audio file or image from a public URL (direct file links and YouTube URLs both work). | | `search_youtube` | read | `query`, `result_threshold?=10`, `duration?=medium` | Search YouTube and return titles, URLs and metadata, useful for finding URLs to pass to `upload_media`. | | `search_videos_by_title` | read | `collection_id?=default`, `query` | Find videos in a collection whose title matches a natural-language query. | | `update_video` | update | `video_id`, `collection_id?=default`, `name` | Update a video's display name. | | `generate_thumbnail` | create | `video_id`, `collection_id?=default`, `time_seconds?` | Get the default thumbnail of a video, or generate one from a specific timestamp (in seconds). | | `list_thumbnails` | read | `video_id`, `collection_id?=default` | List every thumbnail image generated for a video, with image IDs and URLs. | | `get_media_download_url` | read | `media_id`, `collection_id?=default` | Get a signed, time-limited download URL for an audio file (`a-`) or image (`img-`). | | `transcode_media` | create | `source`, `callback_url`, `mode?=economy`, `resolution?`, `quality?`, `framerate?`, +3 more (see below) | Start a transcode job for a video at a public URL: change resolution, quality, framerate or aspect ratio, or mute audio. | | `get_transcode_status` | read | `job_id` | Get the status and output of a transcode job started by `transcode_media`. | | `delete_video` | destructive | `video_id`, `collection_id?=default` | Permanently delete a video from a collection. | | `delete_audio` | destructive | `audio_id`, `collection_id?=default` | Permanently delete an audio file from a collection. | | `delete_image` | destructive | `image_id`, `collection_id?=default` | Permanently delete an image from a collection. | | `remove_video_storage` | destructive | `video_id`, `collection_id?=default` | Delete the stored media bytes of a video while keeping its record, indexes and transcripts. | #### `list_assets` inputs | Field | Type | Required | What it is | | - | - | - | - | | `collection_id` | `string` | no | Scope to one collection.

starts with `connect_rtstream`. Indexes, understandings and alerts attach to a stream that is already connected and ingesting. * `get_rtstream_transcript` needs transcription running, started either by `connect_rtstream` with `enable_transcript` or by `set_rtstream_transcript_status`. * `search_rtstream` needs a scene index or an understanding-backed index on the stream. * `create_rtstream_index` needs an `understand_rtstream` job started with `store=true`. * `create_rtstream_alert` needs an event from `create_event` and an index to attach it to. Alerts cannot be deleted, only disabled with `set_rtstream_alert_status`. * `list_rtstreams` is account-scoped, not per collection. Each row carries its own `collection_id`. * Alert tools take `index_kind` to say which index the `index_id` belongs to: `scene_index` for one built by `index_rtstream_scenes` or `index_rtstream_audio`, `index` for one built by `create_rtstream_index`. * A write that runs long comes back as `status: "processing"` with a `retry_with`: `connect_rtstream` names `list_rtstreams`, `export_rtstream_recording` names `get_video`, `index_rtstream_scenes` and `index_rtstream_audio` name `list_rtstream_scene_indexes`, `understand_rtstream` names `list_rtstream_understandings`, `create_rtstream_index` names `list_rtstream_indexes`, `create_event` names `list_events`, `create_rtstream_alert` names `list_rtstream_alerts`. ## meetings Send a recorder bot into a meeting and collect the recording. | Tool | Kind | Inputs | What it does | | - | - | - | - | | `record_meeting` | create | `meeting_url`, `collection_id?=default`, `bot_name?`, `bot_image_url?`, `meeting_title?`, `time_zone?=UTC`, `callback_url?` | Send a VideoDB recorder bot to a Zoom, Google Meet or Microsoft Teams meeting URL. | | `get_meeting` | read | `meeting_id`, `collection_id?=default` | Get the state of a recorder bot: status (initializing, joined, processing, done), the recorded `video_id` once done, and the speaker timeline when available. | **Prerequisites** * `record_meeting` comes back as soon as the bot is dispatched, with `status: "processing"` and `retry_with: get_meeting`. Poll `get_meeting` until `status` is `done`. Only then does `video_id` have a value. ## Not exposed | Feature | Why not | | - | - | | AI generation: image, music, sound effect, voice and video generation, dubbing, voice clones | Excluded by connector policy. Use the SDKs. | | Text generation | The client is already a language model. | | Local-path uploads and `play()` | These need your filesystem or a browser on your machine. | | Desktop capture, capture sessions and their client tokens | Capture runs through a native binary on your machine over a long-lived connection. A remote server cannot drive it. | For generation, use the [generative media guides](/pages/act/generative-media/index).
