Security audit

Hyperliquid US Stock Perps (Maneki via Finch)

Security checks for vulnerabilities and agentic risk

Overview

The skill provides market analysis through disclosed external services and requires explicit approval for paid runs.

Your ticker and question will be sent to Finch and Maneki AI. Avoid including private account details or confidential trading information. Paid runs require your explicit approval. Review the connection instructions before adding the MCP server; that external guide was unavailable during this review.
