### Description (declared)

# Slack MCP Server

<!-- mcp-name: io.github.workos/slack-mcp-server -->

A production-ready [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server for Slack workspace operations. Connect any AI agent to Slack — send messages, manage channels, search conversations, react to messages, upload files, and look up user profiles.

**This is an independent, generalized MCP server.** It is not tied to any specific project and can be connected to any AI agent that supports MCP (Claude Desktop, Cursor, WorkOS, or custom agents).

## Features

- 📨 **Messaging**: Send messages, read channels, reply to threads, send DMs
- 📁 **Channels**: List, create, archive channels, set topics
- 🔍 **Search**: Full-text search across workspace messages
- 😀 **Reactions**: Add/remove emoji reactions, pin/unpin messages
- 👤 **Users**: Look up user profiles (name, email, title, status)
- 📎 **Files**: Upload text files to channels
