A local MCP server that runs PowerShell through a Node.js program. PowerShell is a command-line and scripting tool commonly used for automating tasks on Windows.

Use it to connect an MCP client to the specified PowerShell server for Windows-related command-line or automation work.

It gives an MCP client access to the configured PowerShell server so an agent can work with that environment. The input does not describe which commands or operations the server exposes.

Security

Grade A, and why

powershell scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
