Windows CLI MCP Server

# serverCwdInitialization - **launch outside allowed paths leaves cwd undefined** – starting the server in a disallowed directory results in no active working directory. - **execute_command fails when cwd undefined** – commands without a workingDir return an error when no active directory is set. - **set_current_directory sets active cwd** – using the tool successfully changes the active directory and calls `process.chdir`. - **get_current_directory reports unset state** – retrieving the current directory before one is set returns a helpful message. - **initialDir sets active cwd when valid** – a valid `initialDir` is used at startup and becomes the active directory. - **initialDir chdir failure falls back to process.cwd()** – if changing to `initialDir` fails the server falls back to the process directory. - **initialDir not in allowedPaths leaves active cwd undefined** – when restrictions prevent using the configured `initialDir`, the active directory remains unset.
