What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
execSync(info.upgradeCommand, { stdio: "inherit" });
const stagingDir = path.join(repoRoot, STAGING_DIR_NAME, runId);
return subprocess.run(cmd).returncode
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Catch bad animations before they ship. Deterministic motion audit + vision-LLM design review.
Deterministic MCP for statistical classifications and survey codelists with provenance.
Local-first static repository security and configuration drift auditor (CLI, GitHub Action & MCP).
Local GitHub Actions/CI maintenance check (action pinning, token perms). Not a full security audit.
A deterministic A-F grade for a repo without running it, plus a verify loop: plan, fix, diff.
Independent static verification for exact immutable public GitHub commits.
