Tool: get_course_roster

Retrieves the teachers and students enrolled in a course, with their user IDs, names, and email addresses. Use student IDs as assigneeIds when creating coursework or announcements, and as studentIds in list_course_work_submissions or get_guardian_info.

To link the user to the People page of a course in the Classroom web app, use https://classroom.google.com/r/{course_id}/sort-name. Use IDs exactly as returned; never guess or modify them.

Tool Annotations

Tool annotations are sent to MCP clients to describe the basic risk of a given tool. Most clients treat these hints as untrusted, but they can be used to decide when a confirmation prompt might be sent to a user.

Along with the title string, the following boolean hints are defined as follows:

  • readOnlyHint: If true, the tool doesn't modify its environment. Default: false.
  • destructiveHint: If true, then the tool can perform destructive actions. If false, then the tool can only perform additive actions. Default: true.
  • idempotentHint: If true, then calling the tool repeatedly with the same arguments will have no additional effect on its environment. Default: false.
  • openWorldHint: If true, then the tool can interact with an 'open world' of external entities. If false, then the tool can only interact with internal entities. For example, a web search tool would be open world, while a memory tool would not be open world.

Destructive Hint: ❌ | Idempotent Hint: ✅ | Read Only Hint: ✅ | Open World Hint: ❌
