What the code does

Capabilities

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 child = spawn(process.execPath, [memoirBin, 'push'], {
    return path.join(appData, appName, 'User');
Executes code built at runtime test-work-view-ui.mjs:45
 vm.runInNewContext(source,context);
          const entries = await fs.readdir(dir, { withFileTypes: true });
const sensitive = /(^|\/)(\.env(?:\..*)?|\.npmrc|\.pypirc|credentials[^/]*|secrets?[^/]*|id_rsa|id_ed25519)$|\.(pem|key|p12|pfx)$/i;

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

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.

Memoir — questions

Answers built from our own checks of this server.

Why is there no uptime for Memoir?
Memoir runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package memoir-cli was installed 226 times last week.
How do I connect Memoir?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls memoir-cli straight from npm; nothing to host, nothing to sign up for.
How many people use Memoir?
The npm package memoir-cli was installed 226 times in the last week. Week over week that is -70%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Memoir open source?
Yes — it is published under the MIT licence, written in JavaScript, 14 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
