get_me · CATS MCP Server MCP: Risk & Policy

WHAT IT DOES

What get_me does on CATS MCP Server

AI agents call get_me to retrieve information from CATS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why get_me needs a policy

This appears to be a read-only operation that retrieves information about the authenticated user (likely current session/profile data). The 'get_' prefix and 'me' parameter are typical of read operations. Without side effects or data modification capability, this falls into the Read category. Severity is low because it only accesses user-level data already accessible to the authenticated session.

From the tool's definition Tool name 'get_me' suggests retrieval of current user information without modification. No description provided, but naming convention implies a standard 'get current user' operation common in API design.
