MisAnthropic is a local command line tool that scans your own computer for configuration traces that could theoretically be used to guess whether the machine belongs to someone in China. It checks things like your system timezone, language settings, leftover Chinese software, package manager mirror settings, and configuration files pointing to Chinese AI service providers. The tool is explicit that it does not make any network requests and does not upload any of its results anywhere. Every check reads local files or environment variables on your own machine, such as timezone files, shell history, package manager configuration files, and settings for tools like Claude Code or CC Switch. Nothing is sent out, and the author states the tool does not claim that any specific product or service actually performs this kind of detection, only that these traces could theoretically be read by something that wanted to. There are twelve separate checks in total, and each is graded by severity from most serious to weakest. Some checks use a graduated scale, so finding a small number of Chinese software traces is treated as a weaker signal than finding many of them at once, which helps avoid a false alarm from a single unrelated file. The tool runs on Windows, inside Windows Subsystem for Linux, and on plain Linux, though the amount it can check varies depending on which of those it detects it is running on. Usage is through a simple command line interface with options for colored output, JSON output, a short summary only, a fix suggestions mode, and a debug mode that shows checks that did not find anything. Installing it requires Node.js version 14 or newer, and it can be run directly or installed globally. The project is released under the AGPL 3.0 license.
