Security Report
Obol MCP is a well-architected payment/API marketplace server with thoughtful security features (signed receipts, runtime response scanning, spending limits, idempotency). However, it has two medium-severity issues: (1) the agent's private key is read from an environment variable without validation that it's actually been set before use in some code paths, and (2) the spending limit enforcement can fail open on network errors, allowing unlimited spending if the facilitator is unreachable. The codebase is clean, dependencies are legitimate, and permissions appropriately match its purpose as a financial/payment tool. Supply chain analysis found 4 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue (1 critical, 0 high severity).
