Once connected, Slack exposes the following actions. The AI can call them with #-mentions in chat, an agent can be granted a subset as tools, and a workflow can run them in an integration-action node.
| Action | Type | What it does | Proxy |
|---|---|---|---|
List Channelslist-channels | Read | List public and private channels in the workspace. | Yes |
Search Messagessearch-messages | Read | Search Slack messages. | — |
Send Messagesend-message | Write | Post a message to a Slack channel. | Yes |
Create Channelcreate-channel | Write | Create a new public or private Slack channel. | Yes |
Add Reactionadd-reaction | Write | Add an emoji reaction to a message. | Yes |
Actions tagged Write create, update, or delete data. In chat and agent paths they pause for your confirmation before running; workflows treat their deterministic wiring as implicit consent. Agent tools covers how to scope which actions an agent may use.
Slack is governed per organization: an admin sets a monetary spend cap and a monthly call quota. A quota of 0 disables the integration — it never means unlimited. See the Integrations overview for the full governance model.
