listComments
AI agents call listComments to retrieve information from Todoist MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool follows the read pattern (list = retrieve data with no side effects). No modification, deletion, or execution of external operations occurs. The empty description is uninformative but does not contradict the safe read classification suggested by the tool name.
From the tool's definition Tool name 'listComments' indicates a list/query operation that retrieves comments without modifying data. The empty description is consistent with a read-only operation to enumerate or fetch existing comments.
