AI agents call discussion_entries 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 discussion forum entries from the Canvas LMS without modifying, deleting, or executing any operations. It is a straightforward read operation on academic discussion data. The low severity reflects that unauthorized access to discussion entries, while a privacy concern, does not directly enable financial harm, data destruction, or code execution.
