  • Text reversal functionality that takes an input string and returns its reversed version. - Supports both stdio and SSE modes for server communication.
  1. Reversing text strings for data processing tasks.
  2. Integrating with other applications that require text manipulation.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "mcp-server-demo-capybara-sfw": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-server-demo-capybara-sfw"
      ]
    }
  }
}

      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
