FAQ from PowerShell MCP Server

What are the prerequisites?

Windows 10/11 or Windows Server 2016+, Node.js 18.0.0+, PowerShell 5.1+ or PowerShell Core 7+, and the Claude Desktop application.

How does the server ensure security?

It uses -ExecutionPolicy Bypass and -NoProfile for safe PowerShell execution, validates all inputs with Zod schemas, disposes sessions after use, and logs operations to stderr without interfering with JSON-RPC.

Where is the Claude Desktop configuration stored?

The configuration file is located at %APPDATA%\Claude\claude_desktop_config.json. The setup script automatically applies the required settings and creates backups.

How can I troubleshoot if the server won't start?

Check Node.js version (must be 18+), run npm install to ensure dependencies, or test components with node test-server.js. For Claude integration issues, use setup.bat or manually verify the config file.

What's new in recent updates?

Recent versions (v1.1.2) introduced safe configuration management with automatic backups, a recovery tool, and merge capability for multiple MCP server configs. Previous fixes resolved JSON parsing errors and simplified setup.
