Use Slack with Claude, GPT, Gemini and more
Connect Slack once, then ask any model in llmwise to read from it and act in it: 159 actions, with every write shown to you before it runs.
Actions (toolkit version 20260915_00) checked against Composio's Slack toolkit page. Updated .
Short answer
Slack connects to llmwise in one click, and every model can then use its 159 actions: 70 that read and run on their own, and 89 that write and ask you first (33 of them every time). On paid plans, included in the message price.
Try it: Slack in one message
Send this with any model. The model finds Slack's actions for the job and runs them, and the reply shows each one.
Summarize what #product discussed about pricing this week and post the summary in #leadership once I approve it.
| Action | In llmwise |
|---|---|
| Search messages | Reads: runs without asking |
| Send message | Always asks first |
The reads run straight away; the write waits on an approval card with Allow and Deny, and shows what it will do first.

What asks first, and why
Reading needs no approval. Anything that writes asks first, and sending, deleting, payments and sharing always ask.
In Slack, that means delete slack canvas, delete multiple slack list items, delete slack list access, and delete slack list item always wait for your yes.
Always allow can switch off the question for one of Slack's 56 other writes, and a reply that has read outside content asks again anyway. One reply runs up to 10 actions, each result read up to 50,000 characters.
Where your Slack data goes
Each action runs through Composio and Slack's own service, which receive its inputs; the result is shown in your chat and saved with it. Composio holds the sign-in, encrypted. More in the Privacy Policy.
