## If you uninstall the app

 
 Pick a channel that belongs to just your workspace. Claude can decline to reply in [guest and shared channels](/docs/claude-tag/admins/troubleshooting#guest-and-shared-channels).
 
+## If you uninstall the app
+
+Uninstalling the Claude app from your workspace removes it from Slack and deletes the workspace's Claude data on Anthropic's side, the same way [disconnecting the workspace](/docs/claude-tag/admins/workspaces#revoke-a-pairing) from the Claude console does. What Claude posted in Slack, such as messages, canvases, and files, stays in Slack under your workspace's own retention settings.
+
+On Enterprise Grid, this applies when the app was installed on an individual workspace and you uninstall it there. Removing an org-wide installation, from the whole grid or from one of its workspaces, doesn't delete data on its own; to delete it, ask the Claude organization Owner to disconnect the grid in their Claude settings.

 ## Where Claude reads and posts
 
-Claude reads and posts only in channels a workspace member has added it to, and in direct messages. Any workspace member who opens a direct message with Claude receives its welcome message, whether or not they've linked a Claude account. Installing the app does not add it to any channel.
+Claude reads and posts only in channels it has been added to, and in direct messages. Any workspace member who opens a direct message with Claude receives its welcome message, whether or not they've linked a Claude account. Installing the app does not add it to any channel.
 
 A member can add Claude to a channel in one of two ways:
 

 * Invite it with `/invite @Claude` in the channel
 * Select **Add to channel** on a channel Claude suggests in a direct message. Claude's welcome message, the introduction it posts when a member first opens a direct message with it, suggests public channels this way.
 
-When a member selects **Add to channel**, Claude adds itself to that channel using its `channels:join` scope. Slack's audit log records the join as the Claude app, with no inviter shown; the member's selection is not visible in Slack's log. If you see a join in the audit log that no one can explain, a member selected one of these buttons. Claude does not join channels on its own.
+A Claude organization admin can also set [auto-join channel patterns](/docs/claude-tag/admins/restrict-access#block-or-auto-join-channels-by-name), so Claude joins a public channel whose name matches when the channel is created or renamed.
 
+When a member selects **Add to channel** or an auto-join pattern matches, Claude adds itself to that channel using its `channels:join` scope. Slack's audit log records the join as the Claude app, with no inviter shown; neither the member's selection nor the matched pattern is visible in Slack's log. If you see a join in the audit log that no one can explain, a member selected one of these buttons or an auto-join pattern matched. Outside those two paths, Claude does not join channels on its own.

 Reading a channel's full history requires being added there. Workspace search can surface public-channel content, the same as any app with the search scope.
 
 Slack Connect channels (shared with another company) are always excluded, regardless of configuration.

# What the Claude Slack app can access

> What the Claude app reads and posts in Slack, the OAuth scopes it requests, and what installing it does not grant. Written for the Slack admin approving the install.

<BetaNote />

You're approving the Claude app install for someone who's setting up Claude Tag. This page covers what the app can do in your Slack workspace. The rest of setup happens on their side, in the Claude console; you don't need a Claude account.

## Where Claude reads and posts

Claude reads and posts only in channels a workspace member has added it to, and in direct messages. Any workspace member who opens a direct message with Claude receives its welcome message, whether or not they've linked a Claude account. Installing the app does not add it to any channel.

A member can add Claude to a channel in one of two ways:

* Invite it with `/invite @Claude` in the channel
* Select **Add to channel** on a channel Claude suggests in a direct message. Claude's welcome message, the introduction it posts when a member first opens a direct message with it, suggests public channels this way.

When a member selects **Add to channel**, Claude adds itself to that channel using its `channels:join` scope. Slack's audit log records the join as the Claude app, with no inviter shown; the member's selection is not visible in Slack's log. If you see a join in the audit log that no one can explain, a member selected one of these buttons. Claude does not join channels on its own.

Reading a channel's full history requires being added there. Workspace search can surface public-channel content, the same as any app with the search scope.

Slack Connect channels (shared with another company) are always excluded, regardless of configuration.

## Requested scopes

The app requests bot scopes for reading and posting in channels it's a member of, reactions, files, canvases, user lookup, and public-channel search. Slack's install consent screen shows the full current list; treat that as the canonical reference, since the set can change between releases.

Two scopes a Slack admin commonly asks about:

* `channels:join` lets Claude add itself to a public channel when a member selects one of its suggested-channel buttons. It cannot join private channels this way.
* `users:read.email` lets Claude match a Slack member to their Claude account by email, so a person who DMs Claude is recognized without a separate linking step.

## What installing does not grant

Credentials for GitHub, Google Drive, a data warehouse, or anything else are provisioned separately by a Claude organization Owner and live on Anthropic's side rather than in Slack.

It responds when @-mentioned, and may respond to other messages it judges warrant a reply.

## After you install

Post `@Claude connect` in any channel with no other text, or send `connect` on its own in a direct message with Claude, and give the code it returns to whoever asked you to install. That code is what pairs your workspace to their Claude organization; it expires after 15 minutes.

Pick a channel that belongs to just your workspace. Claude can decline to reply in [guest and shared channels](/docs/claude-tag/admins/troubleshooting#guest-and-shared-channels).
