Set up Slack in Cursor

officialstdiobroken

Bring Slack into your agent: read channels and threads, post messages and replies, react, and look up users — the team communication layer for agents.

01Configuration

{
  "mcpServers": {
    "slack": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-slack"
      ]
    }
  }
}

Add this to .cursor/mcp.json. Generated from the captured install method (npx); the mcpServers shape is shared across Claude Desktop, Cursor, Windsurf, Cline, and VS Code.

02Steps

Make sure Cursor is installed and up to date.
Open .cursor/mcp.json and add the block above (merge into any existing mcpServers).
Provide any required API keys/credentials as environment variables.
Restart Cursor and confirm Slack’s tools appear.
