安装

选择你的客户端

~/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"
      ]
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

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

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

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

格式与 Claude Desktop 相同。重启 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 使用服务器对象数组，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 保存后热重载。

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 验证，claude mcp remove 卸载。

使用场景

实战用法： slack-mcp-server

How to catch up on unread Slack messages with AI assistance

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

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

前置条件

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

步骤

Get unread summary

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

→ 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.✓ 已复制

→ Thread content with action items extracted
Mark as read

Mark #random and #general as read — I'll skip those.✓ 已复制

→ Channels marked as read

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

注意事项

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

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

前置条件

Slack token configured — Set SLACK_TOKEN environment variable

步骤

Search messages

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

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

Show me the full thread where the final decision was made.✓ 已复制

→ Complete thread with all replies

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

注意事项

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

组合

与其他 MCP 搭配，撬动十倍杠杆

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.✓ 已复制

slack-mcp-server-2 + filesystem

Export Slack conversations to files for documentation

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

工具

此 MCP 暴露的能力

工具	输入参数	何时调用	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

成本与限制

运行它的成本

API 配额: Slack API rate limits: varies by method, typically 50+ req/min for most endpoints
每次调用 Token 数: 300–2000 tokens per tool call
费用: 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

权限、密钥、影响范围

凭据存储： Slack tokens in SLACK_TOKEN environment variable. For stealth mode, extract xoxc + xoxd from browser.

数据出站： 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

常见错误与修复

401 Invalid auth

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

验证： 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.

验证： channels_list

Rate limited

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

验证： Check server logs for retry messages
