createComment · Todoist MCP Server MCP: Risk & Policy

WHAT IT DOES

What createComment does on Todoist MCP Server

AI agents use createComment to create or update resources in Todoist MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Todoist MCP Server environment.

WHY IT NEEDS A POLICY

Why createComment needs a policy

Creating a comment adds new data to a task or project but is reversible (can be deleted via the 'deleteComment' sibling tool). This is a Write operation. Severity is low because comments are non-critical metadata with limited blast radius if created erroneously. Confidence is moderate (0.85) due to the missing description, but the tool name and context provide reasonable certainty.

From the tool's definition Tool named 'createComment' with no description provided. Sibling tools indicate this is a Todoist task management server; 'createComment' follows the naming pattern of reversible data creation operations like 'createTask', 'createLabel', and 'createProject'.
