Slack MCP server
Search messages, post to channels, and read threads from your AI agents.
About
Connect Tracecat to Slack to search messages, post to channels, and read threads for SOC analysts and SRE on-call responders running incident response in Slack. You can post triage findings to the on-call channel the moment a SIEM alert correlates. From there, pull context from war room threads, DM the right user when a phishing alert mentions them, and create canvas documents that keep the audit trail in one place.
