What the code does

We read the source, 4 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.

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.

Pdf4vllm — questions

Answers built from our own checks of this server.

Why is there no uptime for Pdf4vllm?
Pdf4vllm 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 pdf4vllm-mcp was installed 141 times last week.
How do I connect Pdf4vllm?
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 pdf4vllm-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use Pdf4vllm?
The pypi package pdf4vllm-mcp was installed 141 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 Pdf4vllm open source?
We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
