Security Profiles
We recommend different configurations based on your security needs:
Default (Balanced)
By default, the server runs in ConstrainedLanguage mode with a curated blocklist of dangerous commands and restricted system directories. This provides "good enough" defaults for general use, preventing common dangerous operations while allowing most read-only and safe actions.
uvx mcp-server-for-powershell
Safe Mode (Strict)
For environments requiring stricter controls, use NoLanguage mode (--language-mode 0). Only built-in commands and cmdlets can be executed.
uvx mcp-server-for-powershell --language-mode 0
Nuclear Mode (Allow-List Only)
For the highest security "nuclear" option, explicitly whitelist ONLY the commands you need (e.g., allow get-items only). This blocks everything else by default.
uvx mcp-server-for-powershell --allowed-commands Get-Item Get-ChildItem Get-Content
