Kash - Agentic Payment Provider

Security checks across malware telemetry and agentic risk

Overview

This payment skill does what it says: it lets an agent spend from a Kash wallet with disclosed budget and confirmation controls.

Install only if you intentionally want your agent to spend from a Kash wallet. Use a dedicated low-budget Kash agent, set KASH_BUDGET and KASH_SPEND_CONFIRMATION_THRESHOLD according to your risk tolerance, keep KASH_KEY out of chat/logs, and leave KASH_API_URL unset except for local development.

Medium

Category: MCP Least Privilege
Confidence: 91% confidence
Finding: The skill clearly relies on environment variables and outbound network access to perform wallet-funded payments, but it does not explicitly declare those permissions. This creates a transparency and policy-enforcement gap: users or platforms may enable the skill without understanding that it can access secrets and contact external services, increasing the risk of unintended spending or secret exposure if the skill behavior changes or validation is bypassed.
