Send Messages and Notifications to Slack
Post messages, updates, and notifications to any Slack channel or user from your AI agent.
Quick answer: Use the Slack tool through ToolRouter to send messages and notifications to slack directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolSending a status update, a notification, or an alert to Slack sounds simple — but doing it from an automated workflow or an AI agent requires either a custom Slack app, a webhook setup, or a manual copy-paste step that defeats the purpose of automation. Each option adds setup friction that slows down what should be a trivial output step.
The send_message skill posts text messages to any Slack channel or direct message your workspace allows. No webhook configuration required — your agent can send updates, summaries, or alerts directly as part of any workflow that produces output worth sharing.
Teams routing AI-generated reports to a shared channel, developers pushing automated status updates to an ops channel, and managers sending summaries from a research session to a team channel all use this to close the loop between agent output and team communication.

Claude composes and sends Slack messages based on your conversation — summarise a research session and post it to a channel, send an update after completing a task, or draft and deliver a status message without you having to switch to Slack to type it manually.
How to send messages and notifications to slack
Once connected (see setup above), use the Slack tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- Ask: "Send a message to #updates with this summary: [describe what to send]"
- Claude composes the message and posts it to the specified channel
- Ask: "Also send it to [specific user] as a direct message"
- Confirm the message was sent successfully

Summarise the key findings from our conversation about the competitor analysis and send it to the #strategy channel with a header and three bullet points.
Tips
- Ask Claude to format the message with Slack markdown — bold headings, bullet points, and code blocks
- Specify the channel name exactly as it appears in Slack, including the # symbol
- Ask Claude to write the message for a specific audience — the whole company vs a technical team
