link_github_issue · Scrumdo MCP: Risk & Policy

WHAT IT DOES

What link_github_issue does on Scrumdo

AI agents use link_github_issue 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 link_github_issue needs a policy

Attaching a GitHub issue URL to a ScrumDo card creates or updates a relationship/reference on the card. This is a write operation (creates new data/state on the card) rather than read-only. It is reversible (the link can be removed or changed), so it does not qualify as Destructive.

From the tool's definition Tool description states 'Attach a GitHub Issue URL to a card' — this modifies card metadata by adding a link, a reversible write operation.
