WHAT IT DOES

What get_user_grants does on Linode MCP Server

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

RISK

Why get_user_grants is rated Low

This tool retrieves access control and permission information about users in the Linode infrastructure. While it is read-only (no data is modified), the sensitivity of the data returned (user grants/permissions) elevates severity from low to medium, as exposure of access control details could aid privilege escalation attacks or inform social engineering.

From the tool's definition Tool name 'get_user_grants' indicates retrieval of user permission/access data. Description states '[DEPRECATED] Get a user' suggesting it queries user grant information without modification.
