Setup guide

1

Connect Slack in Cowork settings

Open Cowork, go to Settings > Connectors > Slack. Click "Connect Slack" and authorize via Slack OAuth. Select your workspace and the channels you want Cowork to access.

2

Choose channels to grant access

You can grant access to specific channels only. Start with one or two channels to test before expanding access. Private channels require separate authorization.

3

Set posting permissions

By default, Cowork has read-only access to Slack — it cannot post messages. If you want Cowork to draft messages for your review, enable draft-only mode.

4

Test the connection

Ask Cowork: "List the last 5 messages in #general with author and timestamp." This confirms the connection is working.

Default permissions

  • Read messages from authorized channels
  • Search message history
