WHAT IT DOES

What fork-repository does on GitHub Enterprise MCP Server

AI agents use fork-repository to create or update resources in GitHub Enterprise MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GitHub Enterprise MCP Server environment.

WHY IT NEEDS A POLICY

Why fork-repository needs a policy

Forking creates a new repository copy under the user's account or organization. This is a reversible write operation (the fork can be deleted later) that does not destroy or overwrite existing data. It creates a new resource, placing it in the Write category.

fork-repository Rate-limited

fork-repository 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.
