About this plugin
The plugin connects Claude to Slack's hosted MCP server, letting you search messages, files, users and channels, inspect threaded conversations, send messages, manage canvases and retrieve user profiles. You can interact with these capabilities through natural language or the included workflow commands.
Use it for finding discussions, preparing announcements, generating stand-up updates and summarising channels. It requires access to a Slack workspace, OAuth authentication and approval from the workspace administrator for MCP integration.
