What the code does

We read the source, 3 d 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 dangerous call launch_waveform.trace_file → silica/tools/waveform.py:184, read_waveform.trace_file → silica/tools/waveform.py:110
        subprocess.Popen([binary, trace_file])
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

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.

Silica — questions

Answers built from our own checks of this server.

Why is there no uptime for Silica?
Silica 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 silica-eda was installed 128 times last week.
How do I connect Silica?
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 silica-eda straight from pypi; nothing to host, nothing to sign up for.
How many people use Silica?
The pypi package silica-eda was installed 128 times in the last week. Week over week that is -12%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Silica open source?
Yes — it is published under the AGPL-3.0 licence, written in Python and 13 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.
