Blast Scope runs on your own machine — the client starts it, so there is no endpoint to ping. 232 installs a week from pypi. Last commit 8 Aug 2026.
Contextual blast-radius scoring for shell commands an AI agent is about to run
What the code does
We read the source, 20 min ago · rules 3dff92dd89df
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(
"id_rsa", "id_dsa", "id_ecdsa", "id_ed25519", "credentials", "credentials.json",

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.
