Claude Code

claude mcp add pulsemcp-mcp-servers-experimental-s3 -- npx -y s3-aws-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "pulsemcp-mcp-servers-experimental-s3": {
      "command": "npx",
      "args": [
        "-y",
        "s3-aws-mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
