   2. Click the Open config.toml link on the right.
      The configuration file opens for edit.
   3. At the end of the config.toml file, add the TOML configuration text you copied from the MCP Connect dialog. For example,

      [mcp_servers.fdi-mcp]
      command = "cmd.exe"
      args = ["/d", "/c", 'C:\path\to\mcp\run.bat']
      default_tools_approval_mode = "approve"
      [mcp_servers.fdi-mcp.env]
      

   4. In the args = ["/d", "/c", 'C:\path\to\mcp\run.bat'] line, replace C:\path\to\mcp\run.bat with the actual path where you extracted the MCP Connect tool zip file.
   5. Save the configuration file.
