Koskamo

pwsh-exec MCP

A minimal, transparent PowerShell 7 MCP server for Windows that exposes a single tool, run_command, to execute commands in a fresh pwsh process and return raw exit code, stdout, and stderr. It is stateless, bounded by a 1-300 second timeout, and Windows-hardened for UTF-8 output and fresh PATH reading.
