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.

    execFileSync(bin, args, { cwd, stdio: 'ignore', timeout: 4000, windowsHide: true });
Builds a file path from a variable src/unwire.ts:145, src/init.ts:189
  const filePath = path.join(cwd, relFile);
Page executes code built at runtime site-astro/src/notebook-page.html:381
  mb.innerHTML = morder.filter(([k])=>fr[k]).map(([k,v])=>
In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

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.

coldstart — questions

Answers built from our own checks of this server.

Why is there no uptime for coldstart?
coldstart 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 @cstart/coldstart was installed 238 times last week.
How do I connect coldstart?
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 @cstart/coldstart straight from npm; nothing to host, nothing to sign up for.
How many people use coldstart?
The npm package @cstart/coldstart was installed 238 times in the last week. Week over week that is -29%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is coldstart open source?
Yes — it is published under the MIT licence, written in TypeScript, 10 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
