What Castr (BYOK) is for

Castr (BYOK) lets an AI assistant read your own Castr data through the Castr API with a key you supply (Castr API access token). Read-only: 6 tools (list_live_streams, get_live_stream, get_live_stream_stats, list_sub_second_streams, list_video_folders, list_folder_contents). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.castr.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Castr. Castr and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which Castr live streams do I have?"
• "What are the playback settings of my Castr stream 620e0d57427ff4ddd764515f?"
• "Is my Castr stream online and what bitrate is it sending?"
• "Which of my Castr sub-second streams are online?"
• "What video folders do I have in Castr?"
• "What videos are in my Castr folder 6401?"

What it does

• list_live_streams: List live streams with name, enabled flag, HLS and embed playback URLs and main settings (adaptive bitrate, cloud recording, chat, low latency, rewind). Ingest and restream keys are not returned.
• get_live_stream: Get one live stream's name, enabled flag, playback URLs and settings. Ingest and restream keys are not returned.
• get_live_stream_stats: Get real-time health of a live stream: running status, whether it is alive, current bitrate, retry count and when it opened.
• list_sub_second_streams: List sub-second (ultra low latency) streams with name, enabled flag, online status, creation time, embed URL and thumbnail. Ingest keys are not returned.
• list_video_folders: List video-on-demand folders with name and enabled flag. Page with page and limit.
• list_folder_contents: List the videos in a video folder (root videos only unless include_subfolders is true). Page with page and limit.

BYOK key

You bring your own Castr Castr API access token (https://castr.com/app/manage/api). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.castr.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

• https://developers.castr.com/reference/get_v2-live-streams (the API this connector calls, with a BYOK key)

Live from the Castr API (api.castr.com) with a BYOK key; documentation: https://developers.castr.com/reference/get_v2-live-streams. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Castr. Castr and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Castr account.

Built for: Worldwide. Languages: English.

Castr (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Castr (BYOK) is. Castr (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Castr data: Read your Castr live streams, stream health stats, sub-second streams and video folders with your own API access token and secret. You bring your own Castr Castr API access token; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Castr call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.castr.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Castr rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Castr receives. The request we make on your behalf, including the key and the arguments, under Castr's own terms and privacy policy. Castr acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Castr gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Castr data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Castr (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Castr at any time to end all access.

Children. Castr (BYOK) is a general-audience service operated by the adult using the assistant, under Castr's own age rules.

Changes. We will post changes here with a new effective date.
