WHY IT NEEDS A POLICY

Why process_person needs a policy

With an empty description, the tool's behavior cannot be determined. The name 'process_person' is ambiguous — it could mean reading, writing, or processing person-related data. Given the server context (a learning/demo weather MCP server), it is likely benign, but confidence is very low. Defaulting to 'Other' with low severity until more information is available.

From the tool's definition Tool name is 'process_person' but description is empty/uninformative; no description provided to determine actual behavior.
