Slack API에 접근하기 위한 MCP(모델 컨텍스트 프로토콜) 서버입니다. 이 서버는 AI 비서가 표준화된 인터페이스를 통해 Slack API와 상호작용할 수 있도록 합니다.

교통 지원

이 서버는 전통적 및 현대적 MCP 전송 방식을 모두 지원합니다:

• Stdio Transport (기본): 로컬 통합을 위한 프로세스 기반 통신
• 스트리밍 가능한 HTTP 전송: 웹 애플리케이션 및 원격 클라이언트를 위한 HTTP 기반 통신

특징

사용 가능한 도구:

• slack_list_channels - 페이지네이션을 포함한 작업 공간 내 공개 채널 목록
• slack_post_message - 슬랙 채널에 새 메시지를 게시하세요
• slack_reply_to_thread - 슬랙에서 특정 메시지 스레드에 답장
• slack_add_reaction - 메시지에 반응 이모지를 추가하세요
• slack_get_channel_history - 채널에서 최근 메시지 받기
• slack_get_thread_replies - 메시지 스레드에서 모든 응답을 받아요
• slack_get_users - 작업 공간 내 모든 사용자의 기본 프로필 정보를 조회합니다
• slack_get_user_profiles - 여러 사용자의 프로필 정보를 대량으로 수집하기 (배치 작업에 효율적)
• slack_search_messages - 강력한 필터로 작업 공간 내 메시지를 검색합니다:
• 기본 쿼리 검색

slack-mcp-server

A MCP(Model Context Protocol) server for accessing Slack API. This server allows AI assistants to interact with the Slack API through a standardized interface.

Transport Support

This server supports both traditional and modern MCP transport methods:

• Stdio Transport (default): Process-based communication for local integration
• Streamable HTTP Transport: HTTP-based communication for web applications and remote clients

Features

Available tools:

• slack_list_channels - List public channels in the workspace with pagination
• slack_post_message - Post a new message to a Slack channel
• slack_reply_to_thread - Reply to a specific message thread in Slack
• slack_add_reaction - Add a reaction emoji to a message
• slack_get_channel_history - Get recent messages from a channel
• slack_get_thread_replies - Get all replies in a message thread
• slack_get_users - Retrieve basic profile information of all users in the workspace
• slack_get_user_profiles - Get multiple users’ profile information in bulk (efficient for batch operations)
• slack_search_messages - Search for messages in the workspace with powerful filters:
  • Basic query search
  • Location filters: in_channel
  • User filters: from_user, with
  • Date filters: before (YYYY-MM-DD), after (YYYY-MM-DD), on (YYYY-MM-DD), during (e.g., “July”, “2023”)
  • Content filters: has (emoji reactions), is (saved/thread)
  • Sorting options by relevance score or timestamp

Quick Start

Installation

npm install @ubie-oss/slack-mcp-server

NOTE: Its now hosted in GitHub Registry so you need your PAT.

Configuration

You need to set the following environment variables:

• SLACK_BOT_TOKEN: Slack Bot User OAuth Token
• SLACK_USER_TOKEN: Slack User OAuth Token (required for some features like message search)
• SLACK_SAFE_SEARCH (optional): When set to true, automatically excludes private channels, DMs, and group DMs from search results. This is enforced server-side and cannot be overridden by clients.

You can also create a .env file to set these environment variables:

SLACK_BOT_TOKEN=xoxb-your-bot-token
SLACK_USER_TOKEN=xoxp-your-user-token
SLACK_SAFE_SEARCH=true  # Optional: Enable safe search mode

Usage

Start the MCP server

Stdio Transport (default):

npx @ubie-oss/slack-mcp-server

Streamable HTTP Transport:

npx @ubie-oss/slack-mcp-server -port 3000

You can also run the installed module with node:

# Stdio transport
node node_modules/.bin/slack-mcp-server

# HTTP transport  
node node_modules/.bin/slack-mcp-server -port 3000

Command Line Options:

• -port : Start with Streamable HTTP transport on specified port
• -h, --help: Show help message

Client Configuration

For Stdio Transport (Claude Desktop, etc.):

{
  "slack": {
    "command": "npx",
