slack-mcp-server

제작: korotovsky · korotovsky/slack-mcp-server

The most powerful Slack MCP server — stealth mode, DMs, group DMs, unread messages, search, and Enterprise/GovSlack support.

slack-mcp-server is a Go-based MCP server providing 15 tools for Slack workspace interaction. Supports three auth modes: stealth (no permissions needed, uses xoxc/xoxd tokens), OAuth (xoxp), and bot (xoxb). Features include channel history with smart pagination, unread message fetching with @mention filtering, message search, DM/group DM support, reactions, user group management, and Enterprise/GovSlack compatibility.

}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

}

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

How to catch up on unread Slack messages with AI assistance

👤 Busy professionals drowning in Slack notifications ⏱ ~10 min beginner

언제 쓸까: Monday morning or after PTO — you have hundreds of unread messages across channels.

사전 조건
  • Slack token (xoxc/xoxd for stealth, xoxp for OAuth) — Extract from browser cookies or create via Slack app settings
흐름
  1. Get unread summary
    Show me all my unread Slack messages, prioritized by @mentions first, then channels with most activity.✓ 복사됨
    → Prioritized list of unread channels with message counts and highlights
  2. Read key threads
    Show me the full thread for the @mention in #engineering. Summarize what they need from me.✓ 복사됨
    → Thread content with action items extracted
  3. Mark as read
    Mark #random and #general as read — I'll skip those.✓ 복사됨
    → Channels marked as read

결과: Inbox zero on Slack in 10 minutes instead of 30.

함정
  • Stealth mode tokens expire periodically — Re-extract xoxc/xoxd tokens from your browser when they expire

Search Slack history for decisions and context

👤 Anyone who needs to find a specific conversation or decision from the past ⏱ ~5 min beginner

언제 쓸까: You need to find that one Slack message where a decision was made weeks ago.

사전 조건
  • Slack token configured — Set SLACK_TOKEN environment variable
흐름
  1. Search messages
    Search Slack for messages about 'API redesign' from the last month in engineering channels.✓ 복사됨
    → Matching messages with timestamps, authors, and context
  2. Get the full thread
    Show me the full thread where the final decision was made.✓ 복사됨
    → Complete thread with all replies

결과: Found the specific conversation with the context you needed.

함정
  • Search only works within channels you have access to — If a message was in a private channel, you need to be a member

문제 해결

자주 발생하는 오류와 해결

401 Invalid auth

Your Slack token expired or is invalid. Re-extract browser tokens (stealth) or regenerate the OAuth/bot token.

확인: curl -H 'Authorization: Bearer $SLACK_TOKEN' https://slack.com/api/auth.test
Channel not found

Use the channel name with # (e.g., #general) or the channel ID. Run channels_list to find the correct identifier.

확인: channels_list
Rate limited

Slack has per-method rate limits. The server handles backoff automatically, but reduce concurrent requests.

확인: Check server logs for retry messages
