What the code does

We read the source, 22 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 bitatlas_get_file.file_path → mcp-server/index.js:586
      const fileBuffer = fs.readFileSync(filePath);
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.

This one needs environment variables set before it will start: BITATLAS_API_KEY (Your BitAtlas API key (starts with ba_). Generate one at https://bitatlas.com/vault/settings), BITATLAS_MASTER_KEY (Your hex-encoded 256-bit master key (64 hex chars). Required for file upload and download. Derived from your password client-side — never sent to BitAtlas servers.), BITATLAS_API_URL (BitAtlas API base URL (default: https://api.bitatlas.com)), BITATLAS_WEB_URL (Web origin used to build share links (default: https://www.bitatlas.com)). The author declared them in the registry entry; get the values from the project itself.

Bitatlas — questions

Answers built from our own checks of this server.

Why is there no uptime for Bitatlas?
Bitatlas 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 @bitatlas/mcp-server was installed 28 times last week.
How do I connect Bitatlas?
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 @bitatlas/mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use Bitatlas?
The npm package @bitatlas/mcp-server was installed 28 times in the last week. Week over week that is +20%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Bitatlas open source?
Yes — it is published under the MIT licence, written in MDX and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
