}Add this to your Claude Desktop config file. Find it at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS.
What this does
korotovsky/slack-mcp-server exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation. That makes it useful when you want Claude to reach into your team's communication channels without copy-pasting context every turn.
Requirements
This server needs the following environment variables to be set before it can run:
SLACK_MCP_XOXC_TOKEN SLACK_MCP_XOXD_TOKEN SLACK_MCP_XOXP_TOKEN SLACK_MCP_XOXB_TOKEN SLACK_MCP_API_KEY
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
Common use cases
- •Read recent threads, channels, or DMs to summarize team activity
- •Send messages, replies, or status updates as part of a workflow
- •Bring stakeholder context into a Claude conversation without copy-paste
