Slack

Slack's official remote MCP server. An admin has to approve the app; a pasted bot token is not the setup.

Connect to https://mcp.slack.com/mcp. Slack requires OAuth via a registered app, and a workspace admin has to allow it. Only directory-published apps or internal apps can use it. Partner clients include Cursor, Claude, and a short list Slack publishes in the docs.

The reference Slack server in modelcontextprotocol/servers-archived is not this product. Do not install a random slack-mcp package in its place.

Setup snippet

{
  "mcpServers": {
    "slack": {
      "url": "https://mcp.slack.com/mcp"
    }
  }
}

Client config shape varies. Cursor and Claude Desktop use mcpServers. VS Code often uses servers. The values above are the part that matters.
