What the code does

We read the source, 18 h ago · rules 3dff92dd89df

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.

  const candidate = path.join(root, encoded);
      child = spawn(cmd, args, { stdio: ['pipe', 'ignore', 'ignore'], shell: process.platform === 'win32' });
  - "**/id_rsa"      # SSH private keys by filename, anywhere (not just ~/.ssh)

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Occasio and you get told the day something new turns up.

Occasio — questions

Answers built from our own checks of this server.

Why is there no uptime for Occasio?
Occasio 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 @occasiolabs/occasio was installed 77 times last week.
How do I connect Occasio?
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 @occasiolabs/occasio straight from npm; nothing to host, nothing to sign up for.
How many people use Occasio?
The npm package @occasiolabs/occasio was installed 77 times in the last week. Week over week that is +137%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Occasio open source?
Yes — it is published under the Apache-2.0 licence, written in JavaScript, 9 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.
