Sol Inbound Watcher Pub

Security checks for vulnerabilities and agentic risk

Overview

The skill is a transparent local Solana watcher, but it claims USDC/token payment support that the included script does not implement.

Review before installing if you need USDC or SPL-token payment confirmation. As written, use it only for native SOL inbound balance increases unless the documentation is narrowed or token-transfer detection is implemented. Configure webhooks only to endpoints you trust because they receive payment event details.

MCP Tool Poisoning
Confidence
95% confidence
Finding
The skill claims to detect inbound SOL and USDC transfers, but the analyzed behavior only detects native SOL balance increases and not USDC or other SPL token transfers. In a payment-confirmation workflow, this can cause agents to miss valid customer payments or make incorrect business decisions based on incomplete monitoring, which is especially dangerous because the skill is marketed for confirming on-chain payment receipt.

Description-Behavior Mismatch

Medium
Confidence
93% confidence
Finding
The skill metadata claims it watches inbound SOL/USDC transfers, but the implementation only checks lamport balance increases on the watched address. As a result, USDC payments will be silently missed, which can cause an agent or downstream business workflow to incorrectly conclude no payment was made or fail to credit a customer after payment.
