Slack MCP server
The team comms layer for agents.
The Slack MCP server lets your agent read channels and threads, post messages and replies, add reactions, and look up users — so it can participate in the team's conversations, not just observe them.
Who it’s for: Teams who want an agent that can report, notify, and respond directly in Slack.
