Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Checks whether it runs in a sandbox flutter_test_app/windows/runner/main.cpp:12

  if (!::AttachConsole(ATTACH_PARENT_PROCESS) && ::IsDebuggerPresent()) {

Runs an external command mcp_server_dart/lib/src/capabilities/dart/dart_lsp_client.dart:74, mcp_server_dart/lib/src/capabilities/visual_capture/desktop_window_screenshot.dart:345, mcp_server_dart/lib/src/capabilities/visual_capture/web_cdp_discovery.dart:51 и ещё 4

      _serverProcess = await Process.start(dartExecutable, ['language-server']);

Builds a file path from a variable mcp_server_dart/lib/src/capabilities/visual_capture/core_image_file_saver.dart:22

    return path.join(baseDir, temporalFolderName);

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
