List the courses you are enrolled in.
AI agents call list_courses to retrieve information from Moodle Student MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves enrolled course information without modifying any data. It is a straightforward query operation with minimal risk. Even if misused, it only exposes the user's own enrollment data, limiting blast radius. The 'read-only' constraint on the server and the passive 'list' operation confirm Read category classification with low severity.
From the tool's definition Tool description states 'List the courses you are enrolled in' and server is explicitly described as 'read-only querying'; the tool name 'list_courses' and function perform data retrieval with no modifications or side effects.
