set_card_fields · Scrumdo MCP: Risk & Policy

WHAT IT DOES

What set_card_fields does on Scrumdo

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

WHY IT NEEDS A POLICY

Why set_card_fields needs a policy

The tool operates on ScrumDo boards and the name 'set_card_fields' strongly suggests updating card properties (fields). This is a Write operation—data is created or modified reversibly. Severity is medium because careless field modifications could disrupt task tracking, but the changes are typically reversible (undo/re-edit).

From the tool's definition Tool name 'set_card_fields' indicates it modifies card data. The empty description prevents full assessment, but sibling tools like 'add_card_label', 'assign_card', and 'add_comment' on this ScrumDo MCP server perform reversible data modifications.
