WHAT IT DOES

What unstar_repo does on Forgejo

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

RISK

Why unstar_repo is rated Medium

Unstarring a repository modifies the user's starred repositories list. This is a reversible action (the user can re-star the repository), so it falls under Write rather than Destructive. The blast radius is low as it only affects the authenticated user's star list with no impact on the repository itself or other users.

RECOMMENDED RULE

The rule that runs unstar_repo safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Forgejo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unstar_repo, this is the rule to start with:

unstar_repo Rate-limited

unstar_repo stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
