get_user · OCI MCP Server MCP: Risk & Policy

WHAT IT DOES

What get_user does on OCI MCP Server

AI agents call get_user to retrieve information from OCI 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_user needs a policy

The 'get_user' tool retrieves user information from Oracle Cloud Infrastructure. As a 'get' operation on an OCI server, it queries and returns data without modifying or executing operations. This is a Read operation.

From the tool's definition Tool name 'get_user' combined with server description stating it enables interaction with OCI resources; sibling tools like 'get_alarm', 'get_autonomous_database', 'get_boot_volume' confirm this retrieves resource information.
