The hub asks YouTube for view and manage access. Uploading video files is
the one thing it does not do, because of their size. See
What it can do.
Add the account
1
Open Accounts and press Add account
In the admin screen, open Accounts and press Add account at the top
right.

2
Choose YouTube and press Add account
Under Signs in with, press the circle next to YouTube. The account
name fills in as 
youtube, and OAuth client already has the one your
Google accounts use. Leave both as they are in most cases.Press Add account at the bottom.
3
Press Connect now
When the screen says the account was added, press Connect now. Google’s
sign-in page opens.

4
Choose your Google account
Choose the Google account that owns your YouTube channel.

5
Choose the account that has the channel
If your Google account has a brand account under it, Google asks once more
which one to continue as. Choose the one that holds the YouTube channel you
want analysed. If the channel lives on a brand account, choose the brand
account, or your channel’s analytics will look at the wrong one. If this
screen does not appear, skip it.

6
Continue past the unverified-app warning
Google warns that it has not verified this app. The app is the OAuth client
you made yourself, so this is expected. Press Advanced, then the link at
the bottom that starts with Go to.

7
Press Continue
On the screen saying you are signing back in, press Continue.

8
Check the access and press Continue
This screen shows what the hub will be allowed to do: see, edit and delete
your YouTube videos, ratings, comments and captions. That is what the hub
manages your channel with. Press Continue and you are back in the hub.

9
Check that it says connected
You are done when the 
youtube account shows as connected on the
Accounts screen.

Refresh Claude's tool list
Claude keeps its own copy of the tool list and does not notice a new
account by itself. Refresh Claude’s tool list, then
ask in a new conversation.
What it can do
Ask Claude in plain words. Apart from uploading video files, it can do nearly everything a channel owner does.
Deleting cannot be undone, so it keeps to a few rules. A public video, or one
scheduled to go public, is never deleted: ask Claude to make it private first,
then ask again. A list is deleted one video at a time, a second apart, and
stops as soon as YouTube asks it to slow down. A list too large to leave 2,000
of the day’s 10,000 quota units spare does not start. The hub tells Claude to
ask you which videos before it deletes anything.
To keep the managing tools out of reach, connect through a read-only
connection profile. Those tools do not appear there at
all.
Your channel and other channels
YouTube keeps some figures for everyone and some for the channel’s owner only.
For other channels, Claude compares what is public: whether a video is doing
better than usual for that channel, and how often it posts.
YouTube sets a daily allowance (quota). Searching and managing use more of it
than looking, so check what is left on the
youtube account in the admin
screen.
Daily allowance
YouTube allows 10,000 units a day. The count is per Google Cloud project, the one you used when connecting, soyoutube accounts connected through the same OAuth
client share it. It refills every day at midnight Pacific time.
Staying within it costs nothing. When it runs out you are not charged: YouTube
requests just stop until the refill, and Claude tells you when that is.
Roughly what one request uses:
A day mixed like any of these still fits in 10,000.
A day running the channel (about 5,700, 4,300 left)

Accounts connected earlier
Ayoutube account connected before v0.35.0 keeps working, but managing and
reading comments need one reconnect. When Claude asks you to reconnect, open the
youtube account in the admin screen, press Reconnect, and go through the
Google screens above again.

When it says the YouTube API is turned off
The YouTube API is normally turned on for you when the hub is installed or upgraded. If you are still told it is off, open the link Claude passes along and press Enable. Ask again after a few minutes. It costs nothing. The link opens this page in the Google Cloud console. If the message names the YouTube Analytics API instead, the page title differs but the button is the same. The picture shows the Korean console, where the button reads 사용.
