安裝

選擇你的客戶端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "slack-mcp-server-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/korotovsky/slack-mcp-server"
      ]
    }
  }
}

開啟 Claude Desktop → Settings → Developer → Edit Config。儲存後重啟應用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "slack-mcp-server-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/korotovsky/slack-mcp-server"
      ]
    }
  }
}

Cursor 使用與 Claude Desktop 相同的 mcpServers 格式。專案級設定優先於全域。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "slack-mcp-server-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/korotovsky/slack-mcp-server"
      ]
    }
  }
}

點擊 Cline 側欄中的 MCP Servers 圖示，然後選 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "slack-mcp-server-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/korotovsky/slack-mcp-server"
      ]
    }
  }
}

格式與 Claude Desktop 相同。重啟 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "slack-mcp-server-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/korotovsky/slack-mcp-server"
      ]
    }
  ]
}

Continue 使用伺服器物件陣列，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "slack-mcp-server-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/korotovsky/slack-mcp-server"
        ]
      }
    }
  }
}

加入 context_servers。Zed 儲存後熱重載。

claude mcp add slack-mcp-server-2 -- TODO 'See README: https://github.com/korotovsky/slack-mcp-server'

一行命令搞定。用 claude mcp list 驗證，claude mcp remove 移除。

使用場景

實戰用法： slack-mcp-server

How to catch up on unread Slack messages with AI assistance

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

何時使用： Monday morning or after PTO — you have hundreds of unread messages across channels.

前置條件

Slack token (xoxc/xoxd for stealth, xoxp for OAuth) — Extract from browser cookies or create via Slack app settings

步驟

Get unread summary

Show me all my unread Slack messages, prioritized by @mentions first, then channels with most activity.✓ 已複製

→ Prioritized list of unread channels with message counts and highlights
Read key threads

Show me the full thread for the @mention in #engineering. Summarize what they need from me.✓ 已複製

→ Thread content with action items extracted
Mark as read

Mark #random and #general as read — I'll skip those.✓ 已複製

→ Channels marked as read

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

注意事項

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

何時使用： You need to find that one Slack message where a decision was made weeks ago.

前置條件

Slack token configured — Set SLACK_TOKEN environment variable

步驟

Search messages

Search Slack for messages about 'API redesign' from the last month in engineering channels.✓ 已複製

→ Matching messages with timestamps, authors, and context
Get the full thread

Show me the full thread where the final decision was made.✓ 已複製

→ Complete thread with all replies

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

注意事項

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

組合

與其他 MCP 搭配，撬動十倍槓桿

slack-mcp-server-2 + github

Cross-reference Slack discussions with GitHub PRs and issues

Search Slack for mentions of PR #142, then get the PR details from GitHub and summarize the full context.✓ 已複製

slack-mcp-server-2 + filesystem

Export Slack conversations to files for documentation

Export the full #architecture-decisions channel history to ~/docs/architecture-decisions.md.✓ 已複製

工具

此 MCP 暴露的能力

工具	輸入參數	何時呼叫	成本
conversations_history	channel: str, limit?: int	Fetch messages from a channel or DM	1 Slack API call
conversations_unreads	none	Get all unread messages across channels	Multiple Slack API calls
conversations_search_messages	query: str, filters?	Search messages across workspace	1 Slack API call
conversations_replies	channel: str, ts: str	Get thread replies	1 Slack API call
channels_list	none	List workspace channels	1 Slack API call
users_search	query: str	Find users by name or email	1 Slack API call
conversations_mark	channel: str, ts: str	Mark a channel as read (disabled by default)	1 Slack API call

成本與限制

運行它的成本

API 配額: Slack API rate limits: varies by method, typically 50+ req/min for most endpoints
每次呼叫 Token 數: 300–2000 tokens per tool call
費用: Free — Slack API is free. Enterprise features require Slack Enterprise Grid.
提示: Use conversations_unreads for efficient catch-up instead of reading every channel individually.

安全

權限、密鑰、影響範圍

憑證儲存： Slack tokens in SLACK_TOKEN environment variable. For stealth mode, extract xoxc + xoxd from browser.

資料出站： All calls to Slack API (api.slack.com). Supports proxy configuration.

Stealth mode uses browser session tokens which may violate Slack's ToS in enterprise environments.
Write operations (add_message, reactions) are disabled by default. Enable explicitly via env vars.
Messages may contain sensitive company data. Ensure your AI processing is appropriately scoped.

故障排查

常見錯誤與修復

401 Invalid auth

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

驗證： 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.

驗證： channels_list

Rate limited

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

驗證： Check server logs for retry messages
