Link Slack to Claude

Once connected, Claude can interact with your Slack workspace directly from the conversation window. You can ask Claude to send messages to channels or DMs, search for past conversations, list recent messages, summarise threads, and look up channel members — all without leaving Claude. This makes it easy to communicate with your team, share AI-generated content, and keep track of what's happening in Slack alongside your other work.

The Customize option is found in the left-hand sidebar of the Claude interface at claude.ai. Click it to open the customisation panel, then select Connect your tools to browse and manage all available integrations including Slack.

Yes. Once authorised, Claude can send messages to channels and direct message other members of your Slack workspace. You can simply tell Claude what you want to say and where to send it — for example, "Send a message to the #marketing channel saying the report is ready" — and Claude will post it for you using your Slack account.

During the connection flow, you'll be prompted to select which Slack workspace to link. If you're a member of multiple workspaces, make sure to choose the correct one before clicking Connect. You can disconnect and reconnect at any time to switch workspaces.

Go back to Customize → Connect your tools in Claude and find Slack in your connected integrations. Click the disconnect or remove option to revoke access. You can also remove Claude's access from your Slack workspace under Administration → Installed Apps, where all third-party app permissions are managed.

Tool availability in Claude depends on your plan and region. If Slack appears in your Customize → Connect your tools list, it is available for your account. Claude Pro subscribers generally have access to more tools and higher usage limits for integrated tools. Check the Connect your tools section in your account to see what is currently available.
