Slack

latest · 2025.4.25

Archived reference: Slack channels and messaging.

Install

Needs env vars: SLACK_BOT_TOKEN, SLACK_TEAM_ID — replace the <placeholders> with your values.

Optional SLACK_CHANNEL_IDS limits the channels. Archived upstream; the npm package still works.

claude mcp add slack --env SLACK_BOT_TOKEN=<SLACK_BOT_TOKEN> --env SLACK_TEAM_ID=<SLACK_TEAM_ID> -- npx -y @modelcontextprotocol/server-slack

/mcp confirms it's connected.

Install

Or add it manually in ~/.cursor/mcp.json:

{
  "mcpServers": {
    "slack": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-slack"
      ],
      "env": {
        "SLACK_BOT_TOKEN": "<SLACK_BOT_TOKEN>",
        "SLACK_TEAM_ID": "<SLACK_TEAM_ID>"
      }
    }
  }
}

In claude_desktop_config.json (Settings → Developer → Edit Config), then restart:

{
  "mcpServers": {
    "slack": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-slack"
      ],
      "env": {
        "SLACK_BOT_TOKEN": "<SLACK_BOT_TOKEN>",
        "SLACK_TEAM_ID": "<SLACK_TEAM_ID>"
      }
    }
  }
}

Config entry, any MCP client:

{
  "command": "npx",
  "args": [
    "-y",
    "@modelcontextprotocol/server-slack"
  ],
  "env": {
    "SLACK_BOT_TOKEN": "<SLACK_BOT_TOKEN>",
    "SLACK_TEAM_ID": "<SLACK_TEAM_ID>"
  }
}
