Caveat verdict

drain-mcp

45
🟠 Risky
Significant risk patterns flagged — automated deep scan, not behavioral proof.

Reads local files AND makes external network calls

The skill requires the user's Polygon wallet private key in DRAIN_PRIVATE_KEY to sign real on-chain USDC payment transactions, creating genuine financial risk; while this is disclosed and a dedicated wallet is recommended, the private-key requirement and real financial transactions exceed normal API usage.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.

What it does

These are capability combinations: each listed behavior occurs in the skill, but Caveat detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.

Capability combination critical

Reads local files AND makes external network calls — the capabilities for data exfiltration co-occur (data-flow not verified)
