WHAT IT DOES

What fork_repo does on Forgejo

AI agents use fork_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 fork_repo is rated Medium

Forking a repository creates a new copy of an existing repository under a different account or organization. This is a reversible write operation (the fork can be deleted), not destructive or financial. It creates new data in the system.

RECOMMENDED RULE

The rule that runs fork_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 fork_repo, this is the rule to start with:

fork_repo Rate-limited

fork_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.

The button opens the PolicyLayer dashboard: create your workspace, connect Forgejo, apply this rule, and every fork_repo call is checked against it from then on.
