Obtiene las materias activas del semestre actual.
AI agents call courses to retrieve information from Canvas MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a list of active courses for the current semester from Canvas LMS. It queries existing data without side effects, altering data, or executing operations. This is a standard Read operation with low blast radius—misuse would only expose course information already visible to the authenticated user within their LMS account.
From the tool's definition Tool name 'courses' and description 'Obtiene las materias activas del semestre actual' (Gets the active subjects of the current semester) indicate a read-only retrieval operation. No data modification, deletion, or execution occurs.
