WHAT IT DOES

What vikunja_task_comments does on Vikunja MCP Server

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

RISK

Why vikunja_task_comments is rated Medium

Adding comments creates new data within tasks but is fully reversible (comments can be removed or edited later). This fits the Write category definition: 'creates or modifies data reversibly'. The severity is low because comment operations have minimal blast radius—they affect task metadata in a bounded way with no financial impact, cascading effects, or data destruction.

From the tool's definition Tool description states 'add comments to tasks', which is a create operation that modifies task data reversibly. Comments can be edited or deleted, making this a Write operation rather than Destructive.
