slack-cli
Invoke the slack-cli binary to read and act on a Slack workspace from the command line — list channels, read/search conversation history and threads, fetch unread messages, search users, manage user groups, post messages, add reactions, mark channels read, and manage saved items. Use whenever a task needs Slack data or actions, such as "what are the unread messages in #incidents", "search Slack for the deploy thread", "who is @alice", "post a message to #general", "list channels matching X", "react with :rocket: to that message", "what did the team say about Y", or "show replies in this thread". slack-cli is the no-daemon CLI alternative to the slack-mcp-server; it reads a shared on-disk cache so it is cheap to call repeatedly. Output is JSON by default, so results pipe cleanly into jq.
