What the code does

We read the source, 2 d ago · rules ccca72095570

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

A tool parameter reaches a file or shell call audit.path → lingnao-mcp.js:371
    j = JSON.parse(fs.readFileSync(fp, 'utf8'));
Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Decodes a string and executes it module/lingnao-access-engine.js:555

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.

  child = spawn(process.execPath, [KERNEL], { cwd: ROOT, stdio: ['pipe', 'pipe', 'inherit'] });
      box.innerHTML = html;

A tool parameter here reaches a dangerous call

That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

LingNao — questions

Answers built from our own checks of this server.

Why is there no uptime for LingNao?
LingNao 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 lingnao-mcp was installed 438 times last week.
How do I connect LingNao?
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 lingnao-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use LingNao?
The npm package lingnao-mcp was installed 438 times in the last week. Week over week that is +4767%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is LingNao 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.
