Slack MCP Server: Keep Your AI Agent in Sync with Team Conversations

What It Does

Slack MCP Server bridges your AI agent and your Slack workspace. Instead of manually copying messages or context into Claude or Cursor, your agent can now read channels, search conversations, post updates, and manage threads directly from your IDE or chat interface.

This unlocks practical workflows: ask Claude to summarize a thread, have it search for past decisions on a topic, or post automated status updates to #engineering without leaving your editor. The server handles channel history, thread replies, DMs, file attachments, and workspace metadata—all with automatic rate limiting and pagination built in.

The 1,500+ stars on GitHub reflect real adoption by engineering teams who treat Slack as a knowledge source, not just a chat app. If your team lives in Slack, this server closes the gap between your conversations and your AI tools.

How to Install

npx -y @korotovsky/slack-mcp-server

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "slack-mcp-server": {
      "command": "npx -y @korotovsky/slack-mcp-server",
      "env": {
        "SLACK_BOT_TOKEN": "xoxb-your-token-here",
        "SLACK_TEAM_ID": "your-team-id"
      }
    }
  }
}

You'll need a Slack Bot Token with channels:history, channels:read, chat:write, and users:read scopes. Create one here.

Real-World Use Cases

• Thread summaries at standup: Ask Claude to summarize the last 24 hours of #incidents and pull key decisions into your morning standup notes.
• Context-aware debugging: Search your Slack workspace from Cursor for past discussions about a flaky test, without switching windows.
• Automated notifications: Have Claude monitor a channel, detect important patterns, and post alerts to #ops-urgent when thresholds are hit.
