How do I connect Slack to Operator?

You authorize Slack for your workspace once from the Operator dashboard. Operator holds the connection and refreshes it, so the agent can read and post in the channels you allow without you reauthorizing each time.

Can my agent post and reply in Slack for me?

Yes. It can post messages, reply in threads, react, send direct messages, and read channel history. People have it run a daily standup post, summarize a busy channel on request, or drop an alert into a channel when something changes in another app they have connected.

Can it watch a channel and act on what it sees?

It can read recent messages, pull out what matters, and either summarize them back to you or trigger an action somewhere else, like filing a flagged message as a task or pinging you when a keyword shows up. You tell it what to watch for and what to do.

Do I need to build a Slack bot or paste a token?

No. You authorize Slack through its normal app install flow and Operator manages the connection, so there is no bot to code, no token to paste, and nothing to host.

Connect Slack to OpenClaw on Operator.io

Slack is a channel-based messaging platform for teams and organizations. It helps people collaborate in real time, share files, and connect all their tools in one place.

Automate Slack with AI

Your OpenClaw agent lives on Operator and treats Slack as one more service it can drive. Send it an outcome in a Telegram or Discord message and it works out which of the 145 Slack actions to run, then runs them.

Your agent reaches Slack directly or through connectors like Composio MCP and Pipedream MCP, which handle the sign in and token refresh for you, so there is nothing to wire up and no API keys to paste.

What your agent can do with Slack

Your agent can call any of these Slack actions by name as part of a larger task. Ask for the outcome you want and it picks the right ones.

How to connect Slack

You authorize Slack once from your dashboard. Operator holds the connection and refreshes the access tokens on its own, so your agent keeps working with Slack without you signing in again. The same setup unlocks every other app your agent can reach, so you only do it once.

When you are ready, the get started guide walks through standing up your OpenClaw agent.
