PinRAG runs on your own machine — the client starts it, so there is no endpoint to ping. 290 installs a week from pypi. Last commit 10 Apr 2026.
MCP RAG: index PDFs, repos, YouTube, Discord, text; optional YouTube vision; query with citations.
What the code does
We read the source, 5 d ago · rules 995398eba69f
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.
result = subprocess.run(cmd, check=False, capture_output=True, text=True)
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
