How to Connect Claude to Slack (and Is It Safe?)

Claude connects to Slack as an app you message and as a connector that searches your workspace. A Slack admin must approve the app first.

Picks: 3; ranked

Claude works with Slack in two ways. The Claude in Slack app lets you message Claude inside Slack, and the Slack connector lets Claude in claude.ai search your channels, direct messages and files.

A Slack admin has to approve the app first. The connector also needs a Claude Team or Enterprise plan, and the app has to be installed before you turn it on.

Anthropic's newer Slack product is Claude Tag, which gives a team one Claude set up by an admin.

Good for

Team members who want to ask Claude about a thread without leaving Slack
People who need to find past decisions across channels, DMs and files

Permissions

Medium risk

The connector can search your channels, direct messages and files, and the Claude app can reply in the channels you add it to. Ask your Slack admin where the app is added, and turn on the connector only if searching direct messages is acceptable.

What it can do

Read your data
Create and change things
Delete things
Read-only mode

Watch out for

The connector searches DMs and files too
It reads channels, direct messages and files in your workspace to answer, so use it only where your team agrees to that. claude.com
The earlier app answers when you message it
Anthropic says you reach the earlier Claude in Slack app in direct messages, the AI assistant panel and threads where you mention @Claude. It documents no scopes for this earlier app, so ask your Slack admin to read the install consent screen. claude.com
Claude Tag's Slack app can join public channels
Anthropic describes this for the Claude app installed for Claude Tag, not the earlier app. Through its channels:join scope it can join a public channel after a member selects a suggestion or an auto-join pattern matches, and Slack's audit log shows the join with no inviter. It also requests users:read.email, and answers when mentioned or on other messages it judges to need a reply, only in channels it was added to and in DMs. claude.com
Slack admins approve, Slack retention applies
A Slack admin approves the app, and your workspace's Slack retention rules still apply to messages. Slack chats with Claude stay out of your claude.ai history. claude.com
Owners control the connector
On Team and Enterprise, an Owner enables Slack once under Organization settings > Connectors, and each member connects their own account. claude.com
Claude Tag's Slack app is a separate approval
Anthropic's Slack admin page for Claude Tag describes what that app reads and posts. Anthropic does not say it is the same install as the earlier per-user app, so check which one you are approving. claude.com
