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.

File ships in the package but is absent from the source [пакет] cli.js:1
этот файл ставится пользователю, но в репозитории его нет
    var files = all.filter(function (x) { try { return fs.statSync(path.join(dir, x)).isFile(); } catch (e) { return false; } });
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.

Touches key and credential files firebase-deploy-leak-audit/rules.json:6
…S Firebase's defaults, and this list has no **/.* entry. Every dotfile under the public root — .env, .env.production, .npmrc, .git — is uploaded and served.","fix":"Add \"**/.*\" back to the ignore array."},

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.

Hmrc Fraud Prevention Header Lint — questions

Answers built from our own checks of this server.

Why is there no uptime for Hmrc Fraud Prevention Header Lint?
Hmrc Fraud Prevention Header Lint 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 @readystack/hmrc-fraud-prevention-header-lint was installed 57 times last week.
How do I connect Hmrc Fraud Prevention Header Lint?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @readystack/hmrc-fraud-prevention-header-lint straight from npm; nothing to host, nothing to sign up for.
How many people use Hmrc Fraud Prevention Header Lint?
The npm package @readystack/hmrc-fraud-prevention-header-lint was installed 57 times in the last week. Week over week that is +235%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Hmrc Fraud Prevention Header Lint open source?
No, and the distinction matters: it ships its own licence file rather than a standard open-source licence. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
