Agent Risk Score (v2)

Agent risk 52% (partial, 4 of 7 inputs) If an agent using this tool is wrong, hacked or prompt-injected, how much money can it lose? Higher is safer. Each input links to the vendor's own docs; affiliate links never affect it. How it's calculated · Incidents

Missing: Human approval, Sending funds to new addresses, Transaction preview or simulation. Missing inputs lower the maximum instead of counting as zero.

Who holds the keys	The default setup keeps the keys on a separate signer machine; the agent machine runs a watch-only node source	10 / 20
Spending limits enforced outside the agent	Client-side only: the lnget client takes a --max-cost cap per request source	5 / 20
Human approval	Missing: no official source found yet	missing / 15
Sending funds to new addresses	Missing: no official source found yet	missing / 15
Transaction preview or simulation	Missing: no official source found yet	missing / 10
