What the code does

We read the source, 19 h ago · rules 3dff92dd89df

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 tapp_health.projectDir → vscode-extension/extension.js:281, tapp_health.projectDir → vscode-extension/extension.js:288, tapp_health.projectDir → vscode-extension/extension.js:302 и ещё 1
        fs.writeFileSync(p, r.image.data);
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.

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.

    fs.createReadStream(path.join(root, file)).pipe(response);
  const child = spawn(invocation[0], invocation[1], { detached: true, stdio: "ignore", shell: false });
    .readdirSync(capturesDir, { withFileTypes: true })

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

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.

Tapp — questions

Answers built from our own checks of this server.

Why is there no uptime for Tapp?
Tapp 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 tapp-mcp was installed 1 225 times last week.
How do I connect Tapp?
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 tapp-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Tapp?
The npm package tapp-mcp was installed 1 225 times in the last week. Week over week that is -79%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Tapp open source?
Yes — it is published under the MIT licence, written in JavaScript, 2 stars on GitHub and 15 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
