link_github_commit · Scrumdo MCP: Risk & Policy

WHAT IT DOES

What link_github_commit does on Scrumdo

AI agents use link_github_commit 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_commit needs a policy

This tool creates a new association between a ScrumDo card and a GitHub commit, modifying card metadata. While it doesn't delete or execute external code, it does perform a persistent write operation that links external version control data to the card. The action is reversible (the link could be removed), placing it in the Write category rather than Execute.

From the tool's definition The tool 'link_github_commit' performs an 'Attach' operation, which creates or modifies metadata on a ScrumDo card by associating it with a GitHub commit SHA.
