What the code does

We read the source, 5 d ago · rules ccca72095570

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.

Runs a command on install [пакет] package.json:1
setup.py: выполняет код при установке пакета
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.

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.

Chaos Cypher — questions

Answers built from our own checks of this server.

Why is there no uptime for Chaos Cypher?
Chaos Cypher 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 pypi package chaoscypher-cli was installed 218 times last week.
How do I connect Chaos Cypher?
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 chaoscypher-cli straight from pypi; nothing to host, nothing to sign up for.
How many people use Chaos Cypher?
The pypi package chaoscypher-cli was installed 218 times in the last week. Week over week that is -29%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Chaos Cypher open source?
Yes — it is published under the AGPL-3.0 licence, written in Python, 3 stars on GitHub and 4 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
