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.
const instructionsPath = path.join(projectRoot, 'templates', 'install', filename);
const proc = Bun.spawn(['git', ...args], {
`Cannot update snapshot note "${existing.title}" [${existing.id}]. Snapshots are immutable — create a new dated snapshot instead.`
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.
