Fetch all lessons for a given chapter within a course
AI agents call get_lessons to retrieve information from Aspire MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves lesson data from the database without creating, modifying, deleting, or executing operations. It is a straightforward read operation that navigates the educational content hierarchy as described in the server's purpose. No data is changed, and the blast radius of misuse is minimal—an agent could at worst retrieve unintended lesson content, which is low-severity information disclosure.
From the tool's definition Tool name 'get_lessons' and description 'Fetch all lessons for a given chapter within a course' indicate a retrieval operation with no side effects.
