Stockstar Fund Rating - 证券之星基金评级

Security checks across malware telemetry and agentic risk

Overview

This skill coherently provides public fund-rating lookups and uses only purpose-aligned network fetching and local caching.

Before installing, expect this skill to contact fund.stockstar.com and maintain a local cache of public fund-rating data. Use clearer fund-rating queries or fund codes to avoid accidental activation from broad finance wording.

MCP Least Privilege
Confidence
89% confidence
Finding
The skill invokes a Python script and explicitly relies on network access plus local caching, but it declares no permissions. This creates a transparency and policy-enforcement gap: a host system or reviewer may underestimate the skill's ability to read/write local data and access external resources, which can enable unintended data access or outbound requests without informed approval.

Vague Triggers

Medium
Confidence
84% confidence
Finding
The trigger phrases are very broad terms like '基金' and '评级', which can cause the skill to activate during ordinary financial conversations that were not intended to invoke external data retrieval. Over-broad activation increases the chance of unnecessary network access, confusing responses, or unintended tool use in contexts where the user did not ask for this specific skill.
