get-user · Paragraph MCP: Risk & Policy

WHAT IT DOES

What get-user does on Paragraph MCP

WHY IT NEEDS A POLICY

Why get-user needs a policy

This tool retrieves user profile information without side effects. It is purely a read operation that queries existing data. The severity is low as retrieving a user profile does not expose sensitive financial data (unlike tools like 'get-coin' which accesses token balances) and cannot cause harm if misused by an AI agent.

From the tool's definition Tool name 'get-user' and description 'Get user profile by ID or Ethereum wallet address' indicate a retrieval operation with no modification, creation, or deletion of data.
