What it reached
Network
No connections.

Credentials
None of the planted fake keys were touched.

Files written
Nothing outside its own folder.

We planted fake AWS, SSH, npm and GitHub keys and a .env file before every run. Red means something left or was planted to run later.

Findings

No findings. Detonator observed no malicious or suspicious behavior in the runs below.

run mcp:baseline

Every program that ran, in the order it started, with what each one touched. Red marks the path to a leak or a planted file.

Note

Observed behavior only. A clean result does not prove a package is safe. Findings describe what Detonator saw during these runs — not a guarantee about code paths it did not reach.
