Connect ChatGPT with your LiveReacting account, or Claude Code, Codex, Cursor and other MCP clients with an API key. The agent builds a stream from a playlist, starts it, schedules it and reads the broadcast history afterwards.

Streamable HTTP, POST only, no session. An API key goes in the Authorization header as a Bearer token. ChatGPT signs in with OAuth instead.
One URL and one Authorization header for every client below. The key is the lr_ key the REST API takes, so a key you already have works here.
If you have no key yet, create one in the Developer section of the LiveReacting Studio. Set it as the LIVEREACTING_API_KEY environment variable and restart your client. VS Code asks for the key instead.
In .mcp.json at the root of your project. The key stays out of the file, so it is safe to commit.

}Any client that supports Streamable HTTP and a Bearer header takes the same URL and the same header.
Add ?read_only=1 to the URL and the client is offered only the tools that read. Nothing the agent calls can change a project or a broadcast.
Every name starts with livereacting_, so one search finds the whole server in a client that loads tools on demand.

Each tool's input schema comes from tools/list once you connect, and its description says what to call next and how long to wait between polls. Read them there; do not infer them from the names above.
Add ?toolsets= with any of account, editor, streams, media and analytics, comma-separated, and the client is offered only those groups. The server does the filtering, so any client can use it, and it refuses a name it does not recognize.
Say what the stream should do, in plain words. The agent picks the tools from the table above and calls them in the order the job needs.
"Here are three Google Drive video links. Build a 24/7 live stream on my YouTube channel from them and start it."
It imports the three files, waits until they can be streamed, fills a looping playlist and goes live.
"Schedule last week's webinar recording to go out live on Friday at 3pm."
It finds the recording in your library, builds a project that plays it once, and schedules that one start time.
"We are live. Switch to the interval scene."
It activates the interval scene and pushes the change to the running broadcast. The stream stays live.
"How did last week's broadcasts do?"
It goes through your projects, lists the broadcasts each one ran with their peak viewers, then reads YouTube's numbers for them.
The Free plan and a paused subscription do not include API access. With an API key, every request is refused with 403 API_ACCESS_REQUIRES_PAID_PLAN. Through ChatGPT the account can connect, and each tool call returns that error until the plan includes API access.
Anything the key can reach, the agent can reach. Create it in the Developer section of the Studio, and revoke it there the moment you want the agent to stop.
Add ?read_only=1 for the tools that read, or ?toolsets=streams,media for the groups you name. The server refuses an unrecognized value rather than ignoring it.
It cannot import a YouTube playlist, or build a text, image or interactive overlay. You build those in the Studio, and the agent can still run a stream that has them.
Yes. It can delete a scene, replace a whole playlist, stop a broadcast and cancel a schedule, and the table above marks each of those tools Destructive. With ?read_only=1 on the URL the server offers none of them.
Yes. In ChatGPT, open Plugins, choose Add and then Create MCP App, and enter the server URL above. ChatGPT then asks you to sign in to your LiveReacting account. Claude Code, Codex CLI, Cursor, VS Code and Gemini CLI connect with an API key, and each has a configuration on this page.
Yes, when the agent can run commands on your computer. It asks LiveReacting for upload links, sends the file with curl, and the file joins your library. Each file can be as large as your plan allows. An agent without a terminal can import one file at a time from a direct public link, or from Google Drive, Dropbox or YouTube.
Every tool, every input, every response field and every error code is in the MCP reference. The REST API it sits on is documented beside it.
Build your stream in the studio on the Free plan, which does not expire. Move to any paid plan when you are ready to hand it to an agent, and the API key comes with it.
