About this plugin
The plugin connects your coding agent to a Slack workspace through Slack's hosted MCP server. It can search messages, files, users and channels, read threads, send or schedule messages, manage reactions, work with canvases, and list channel members.
It also provides guidance for Slack API calls, Slack CLI workflows, app development with Bolt, message composition, search, and Block Kit layouts. Use it for retrieving team context while coding or creating and testing Slack apps. OAuth authentication is requested on first use.
