Install this only if you are comfortable providing a Caiyun Weather API token and sending queried coordinates to Caiyun. Use a token intended for this service, and avoid querying locations you consider sensitive.

Medium

• Category: MCP Least Privilege
• Confidence: 92% confidence
• Finding: The skill declares tool access that enables reading environment variables and making network requests via Python, but it does not explicitly declare corresponding permissions. This creates a transparency and policy gap: users or platform controls may not realize the skill can access a secret token and transmit data off-host to an external API, which increases the risk of unintended secret exposure or overbroad capability use.
