Post to Twitch from ChatGPT

ChatGPT drafts it. You approve it. PostDelegate posts it.Twitch: Chat messages and announcements in your channel.

How to post to Twitch from ChatGPT

Add PostDelegate to ChatGPT. In ChatGPT open Settings, then Connectors, then Create. If you cannot create one, look for a developer mode switch under advanced settings, or ask your workspace admin. Name it PostDelegate, paste the server URL below and choose OAuth. Choose Create, then Connect, sign in to PostDelegate and click Authorize.
Server URL
```
https://app.postdelegate.com/mcp-oauth-dynamic
```
Custom connectors depend on your ChatGPT plan and workspace settings, which OpenAI controls.
Connect Twitch in PostDelegate. On the calendar page choose Add Channel, then Twitch. Sign in with Twitch and approve the permissions. PostDelegate asks to read and write chat messages and to manage announcements in your chat.
Ask ChatGPT for a draft. Describe the post in plain words. ChatGPT checks your Twitch channel's rules, creates the post and sends back a preview link.

Teach ChatGPT the posting rules

Paste the PostDelegate instructions into a custom GPT or a Project, with the connector enabled there, so ChatGPT follows the posting rules in every chat. Agent files has the steps.

What to ask ChatGPT

Mention any Twitch setting in plain words and ChatGPT fills it in. Start with something harmless, like asking which channels you have.

Schedule a Twitch announcement in purple for Friday at 19:55: “Stream starts in five minutes.”
Draft three chat messages for tonight’s stream, each under 500 characters, one every half hour from 20:00.

What ChatGPT can do on your Twitch channel

Check the rules first. Before writing, it reads your Twitch channel's length limit (500 characters) and required settings.
Draft, schedule or post. It creates a draft, a scheduled post or an immediate post, and runs the same checks as the app.
Use your media. It attaches files from your media library or adds one from a public link.
Review and fix. It lists what is scheduled, changes the Twitch settings of a post that has not gone out, and deletes posts you no longer want.

Twitch is a live-streaming platform, and a scheduled message is a way to put a reminder, a schedule or a link in chat at a set time. Each post is sent to your channel's chat from your own Twitch account, up to 500 characters of text.

Twitch settings ChatGPT can fill in

Setting	Notes
Message Type	Chat Message (the default) or Announcement. An announcement is highlighted in chat.

Before you start

Messages are text only. Images and video are not sent.
If Twitch stops accepting the saved sign-in, the channel asks you to reconnect and scheduled messages will not send until you do.

The Twitch channel guide has every field, and MCP tools lists exactly what an assistant can and cannot do.

Questions

Will ChatGPT publish to Twitch without asking me?

Not unless you ask it to. Ask for a draft and the post waits on your calendar until you schedule it, and your workspace's approvals apply as usual. Tools that change data are marked as such, so ChatGPT can ask you before it schedules or deletes anything.

Do I need an API key to connect ChatGPT?

No. ChatGPT signs in with your PostDelegate account through your browser. An API key is only for clients that cannot sign in, as described in MCP clients.

Does it cost extra to use ChatGPT with PostDelegate?

No. The MCP server is on every plan, and ChatGPT runs on your own ChatGPT account, so PostDelegate never charges for AI. Every plan starts with a 7-day free trial with no card.

Can ChatGPT attach images or video to a Twitch post?

It can use files already in your media library, or add one from a public link. It cannot fetch files from your computer, so upload those in the app first, or through the upload widget where ChatGPT shows it. See MCP tools.

Can I schedule Twitch announcements as well as chat messages?

Yes. Set Message Type to Announcement and choose a colour: Primary, Blue, Green, Orange or Purple. Announcements are highlighted in chat.

Does the message come from my own Twitch account?

Yes. Each post is sent to your channel's chat from your own Twitch account, as text of up to 500 characters.
