Slack
List channels, search messages, post messages, create channels, and add reactions across your Slack workspace.
Slack is mapped and documented, but one-click connection isn't live yet — the app shows it as Coming soon. Only Google Calendar, Drive, Mail, and Tasks are connectable today; see the Standard integrations catalogue for what's live now.

Actions
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.

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.
Spend & quota
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.
