What the code does

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.

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.

MCP Benchmark Hygiene — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Benchmark Hygiene?
MCP Benchmark Hygiene 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 mcp-benchmark-hygiene was installed 827 times last week.
How do I connect MCP Benchmark Hygiene?
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 mcp-benchmark-hygiene straight from pypi; nothing to host, nothing to sign up for.
How many people use MCP Benchmark Hygiene?
The pypi package mcp-benchmark-hygiene was installed 827 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Benchmark Hygiene open source?
Yes — it is published under the MIT licence, written in Python and 0 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.
