Skip the Slack Admin Queue: Access Your Workspace Data in Minutes

Tired of waiting weeks for admin approval to access your Slack workspace data? This MCP server gives you immediate access to conversations, channels, and threads without creating a single Slack App or bothering IT.

The Admin Approval Problem

You want to feed your team's Slack discussions into Claude or other AI tools for analysis, summarization, or context. But the traditional path requires:

• Creating a Slack App (admin approval required)
• Requesting OAuth scopes (admin approval required)
• Waiting for IT to review and approve (days to weeks)
• Managing bot installations across workspaces

This MCP server sidesteps all of that by using your existing browser session or a simple user token.

Immediate Workspace Access

Browser Token Method (2 minutes):

# Extract tokens from your browser's developer console
# XOXC token from localStorage
# XOXD token from cookies
npx -y slack-mcp-server@latest --transport stdio

User OAuth Method (5 minutes):

# Create a personal app at api.slack.com/apps
# Add basic read scopes, install to workspace
# Use the xoxp- token directly

Both methods give you full read access to channels, DMs, and threads you already have permission to see.

Real Productivity Gains

Meeting Follow-ups Made Automatic Ask Claude to pull the last 50 messages from #engineering-standup and generate action items. The server fetches full conversation history with context, including thread replies and user mentions.

Cross-Channel Context Discovery
"Show me all discussions about the new API from #backend-dev and #product-planning this week." The channels_list tool finds relevant channels, then conversations_history pulls the actual discussions.

Thread Analysis at Scale Point Claude at a long technical discussion thread and ask for a summary of the resolution. The conversations_replies tool pulls the entire thread structure, maintaining reply relationships.

Quick Integration Examples

Claude Desktop Setup (30 seconds):

{
  "mcpServers": {
    "slack": {
      "command": "npx",
      "args": ["-y", "slack-mcp-server@latest", "--transport", "stdio"],
      "env": {
        "SLACK_MCP_XOXP_TOKEN": "xoxp-your-token"
      }
    }
  }
}

Docker for Remote Access:

docker run -e SLACK_MCP_XOXP_TOKEN=xoxp-... \
  ghcr.io/korotovsky/slack-mcp-server \
  mcp-server --transport sse

Smart Features That Save Time

Pagination Handled Automatically: Request 200 messages, get proper cursor-based pagination without manual token management.

Channel Name Resolution: Use #general instead of cryptic channel IDs like C1234567890.

Activity Filtering: Toggle whether you want join/leave notifications included or just actual conversations.

Thread Context: Get complete thread hierarchies, not just individual messages.

Beyond Basic Message Fetching

The server supports both public channels and private DMs/group chats you're already part of. You can:

• Pull conversation history from any timeframe
• Access group DMs and private channels
• Get threaded replies with full context
• Filter by message types and activity

Perfect for AI-powered analysis of team communications, project retrospectives, or finding specific technical discussions buried in chat history.

Production-Ready Architecture

Built in Go with minimal dependencies. Supports both Stdio (perfect for Claude Desktop) and SSE transports (great for web applications). The 2,000+ developers already using it in their workflows have stress-tested the reliability.

Docker support, proxy configuration, and TLS handling mean you can deploy it anywhere from local development to production environments.

The security model is straightforward: you're using your own Slack permissions. No escalated access, no bot management, no token rotation headaches.
