What the code does

We read the source, 57 min ago · rules 995398eba69f

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 run.stdin → tools/parity_probe.py:28
        r = subprocess.run(cmd + [str(p)], input=stdin, capture_output=True, text=True, timeout=120, cwd=d)
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 bin = path.join(dir, `brevi-${target}`, exe);
        out = subprocess.run(['ldd', path], capture_output=True, text=True).stdout
        entries.append((ord(eval('"\\N{%s}"' % n)), 0, n))
Builds a database query by concatenation src/dynpy/py/polars.py:2438
        drop = (list(columns) if isinstance(columns, (list, tuple)) else [columns]) + list(more_columns)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

Brevi — questions

Answers built from our own checks of this server.

Why is there no uptime for Brevi?
Brevi 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 brevi was installed 775 times last week.
How do I connect Brevi?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls brevi straight from npm; nothing to host, nothing to sign up for.
How many people use Brevi?
The npm package brevi was installed 775 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 Brevi open source?
Yes — it is published under the Apache-2.0 licence, written in Rust, 0 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.
